Description

[0001] “A HYDROGEN BURNER”

[0002] FIELD OF THE INVENTION

[0003] The present invention relates to the field of burner. More particularly, the present invention relates to a clean hydrogen burner that ensures clean combustion with minimal environmental impact and also addresses the issue of flashbacks.

[0004] BACKGROUND OF THE INVENTION

[0005] Around one-third of the global population cook using open fires or inefficient stoves fuelled by kerosene, biomass and coal. Such type of cooking practice causes harmful household air pollution. According to the world health organization, household air pollution caused the death of 3.2 million deaths in 2020, including over 2,37,000 deaths of children under the age of five. The combined ambient and household air pollution effects are associated with 6.7 million premature deaths annually. Household air pollution exposure leads to non-communicable diseases, including stroke, ischemic heart disease, chronic obstructive pulmonary disease (COPD) and lung cancer.

[0006] Women and children, typically responsible for household chores such as cooking and collecting firewood, bear the most significant health burden from using polluting fuels and technologies in homes. It is essential to expand the use of clean fuels and technologies to reduce household air pollution and protect health. Modern cooking fuels, such as biogas, liquefied petroleum gas, natural gas, alcohol fuels and biomass stoves are used, and however, they cause emissions causing indoor air pollution.

[0007] Around 91% of the urban Indian population has access to modem cooking fuel. On the other hand, only 53% of the rural Indian population has access to modem cooking fuel. More than 80% of people in Sub Saharan Africa use charcoal, kerosene or firewood for cooking whereas, there are also several people staying at extreme cold climate which are remotely located, and they use harmful fuel for space heating.

[0008] The conventional hydrogen burner available in the market used which uses hydrogen as a fuel are blended in different percentage with the other fossil fuels and burnt to convert it into thermal energy. The mixing of the fossil fuel with the hydrogen causes emission of harmful gases in the environment. Also, these conventional burner are incapable to maintain the proper ratio of fuel-air mixture effecting the flame stability and also these conventional burner are not equipped with gas leak detection sensor and the temperature detection sensor to detect the gas leak and to efficiently manage and manages the flame temperature.

[0009] US10760784B2 discloses a perforated flame holder and burner including a perforated flame holder provides reduced oxides of nitrogen (NOx) during operation. The perforated flame holder includes a pattern of elongated apertures extending between a proximal and a distal surface of the flame holder relative to a fuel nozzle. The perforated flame holder can provide a significantly reduced flame height while maintaining heat output from the burner. However, the drawback of this invention is it uses multiple fuel control valve and fuel nozzle which increase the manufacturing complexity and increases the malfunctioning of the burner.

[0010] US11747013B2 discloses a fuel gas burner apparatus designed to minimize NOX and CO emissions during combustion. It features a burner tile with a primary combustion chamber, flame holders, and primary tubes for optimal fuel-air mixture introduction. The apparatus ensures effective flame anchoring and enhanced combustion efficiency, achieving reduced emissions across varying operational conditions. However, the drawback of this invention is it uses multiple flame holder and primary tubes which leads to uneven fuel air mixing resulting in incomplete combustion of fuel gas affecting the flame stability.

[0011] Several types of burner are available in the market, however the existing burners fails to solve the issue of flashbacks. The flashback occurs when the flame moves to the direction of the fuel source or to the fuel mixing area or along the border to the upstream area. Further the issue of flashback is coupled with higher burner temperatures that cause strong thermal stresses in burners and hinder their performance.

[0012] Therefore, there is a need to develop a sustainable, user-friendly, renewable fuel based a hydrogen burner system that utilizes clean hydrogen as fuel, ensuring clean combustion with minimal environmental impact and provide better flame stability.

[0013] OBJECT OF THE INVENTION The main object of the present invention is to provide a hydrogen burner that uses clean hydrogen as fuel.

[0014] Another object of the present invention is to provide a hydrogen burner that uses clean hydrogen as a fuel ensuring clean combustion with minimal environmental impact.

[0015] Yet another object of the present invention is to provide a hydrogen burner that provides better flame stability.

[0016] Yet another object of the present invention is to provide a hydrogen burner that operates at a wide range of temperature.

[0017] Yet another object of the present invention is to provide a hydrogen burner that incorporates both manual control for users who prefer hands-on adjustments and automatic controls for automated precise temperature management.

[0018] Yet another object of the present invention is to provide a hydrogen burner which releases significantly less radiant heat compared to the LPG flame, resulting in a temperature reduction of 7°C at a distance of 1ft from the flame.

[0019] Yet another object of the present invention is to provide a hydrogen burner that restrict the flash back, due to reduction in pore size of the plate in the hydrogen burner.

[0020] Still another object of the present invention is to provide a hydrogen burner having sensors that activates the alarm and the ventilation system when the hydrogen concentration crosses a threshold limit and cuts the supply of the hydrogen gas to the burner.

This invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein. Rather, the embodiment is provided so that this disclosure will be thorough, and will fully convey the scope of the invention to those skilled in the art.

[0043] The present invention provides a hydrogen burner that utilizes clean hydrogen as fuel, ensuring clean combustion with minimal environmental impact and incorporates both manual control for users who prefer hands-on adjustments and automatic controls for automated precise temperature management. Additionally, the hydrogen burner also eliminates the chances of flashbacks by reducing the pore size of the plate.

[0044] In a main embodiment, the present invention provides a hydrogen burner, comprising a burner assembly, a housing, at least one non-retum valve, at least one flow controller, a set of sensors, a temperature sensor, a gas sensor, and an alarm module. The housing accommodates and supports said burner assembly.

The manifold channel is secured on said manifold plate and said manifold plate is configured to accurately control a flow of fuel gas within a specified area of said manifold plate. The distributor plate is placed above said manifold channel and said distributor plate is configured to equally distribute and diffuse the fuel gas around said burner assembly. The diffusor plate is placed above said distributor plate and said diffusor plate facilitates in mixing of the fuel gas with air and ensures flame stability.

[0045] Referring to Figure 1, a cross-sectional view of a burner assembly of the hydrogen burner according to an embodiment of the present invention is depicted. The burner assembly (130) comprises an insulator plate (131), a manifold plate (132), a distributor plate (133), a diffusor plate (134), a manifold channel (135), a radiator (136), an inlet pipe (137), a flame indicator (138) and an outlet pipe (139).

[0046] The insulator plate (131) is made from a non-metallic insulating material, such as cork or Teflon. The manifold plate (132), constructed from metal, facilitates the formation of the flow channel. The distributor plate (133) is composed of either metal or non-metal woven or non-woven porous material, with a gradient in pore size. The bed features coarser pores at the bottom, transitioning to finer pores at the top. The diffuser plate (134) consists of a microporous bed with pore diameters smaller than 0.6 mm thereby eliminating the chances of flashbacks by reducing the pore size.

[0047] The flame indicator is made of metal mesh, through which the hydrogen flame passes, creating a color change in the flame for easy detection, ensuring safety.

[0048] The radiator (136) is provided to facilitate the supply of hydrogen gas through an inlet pipe (137) connected to the fuel gas storage system. The radiator (136) also acts as a flame arrestor and apprehend the conduction heat towards the hydrogen storage system by keeping the temperature of said inlet pipe (137) low. The outlet pipe (139) of said radiator (136) is connected to said manifold channel (135) and said manifold channel (135) is configured to discharge the fuel gas. In other words, the outlet pipe which is connected to the radiator (136), is further connected to the manifold channel (135) and the manifold channel (135) discharges the fuel gas.

[0049] The manifold channel (135) includes a major manifold (140) and a minor manifold (141). The major manifold (140) is connected to said minor manifold (141) and said major manifold (140) is configured to distribute the fuel gas to said minor manifold (141) and said minor manifold (141) has a plurality of outlet pores configured to efficiently discharge the fuel gas. The manifold channel (135) is secured on said manifold plate (132) and said manifold plate (132) is configured to accurately control a flow of fuel gas within a specified area of said manifold plate (132). The insulator plate (131) is attached to the lower side of said manifold plate (132) and said insulator plate (131) facilitates in minimizing the heat loss from the bottom of the burner.

[0050] The distributor plate (133) is placed above said manifold channel (132) and said distributor plate (133) is configured to equally distribute and diffuse the fuel gas around said burner assembly (130).

[0051] The diffusor plate (134) is placed above said distributor plate (133) and said diffusor plate (134) facilitates in mixing of the fuel gas with air and ensures flame stability and temperature. The diffusor plate (134) placed above said distributor plate (133) promotes uniform mixing of the fuel with the oxygen in the air, resulting in efficient combustion of the hydrogen. The diffusor plate (134) is highly porous (pore diameter <0.6 mm) through which the hydrogen gas flows to top of said diffusor plate (134) and combines with oxygen in the air that helps in creating stable flame on the burner. The porous plate, with its uniformly distributed pores, automatically adjusts the diameter of the discharged gas in response to variations in the fuel gas flow rate, thereby eliminating the chances of flashbacks by reducing the pore size. This dynamic adjustment helps regulate the flame size, ensuring stability and consistency. As the flow rate of the fuel gas changes, the plate modifies the area of the gas release to maintain a steady and controlled flame, which is particularly useful for precise flame management in the burner.

[0052] The flame indicator (138) is placed above said diffusor plate (134) and said flame indicator (138) is configured to indicate the existence of invisible hydrogen flame in the daylight and ensures the safety.

[0053] When hydrogen is mixed in stoichiometric proportions, its flame reaches a temperature of around 2,045°C (or 2,318K) in air, which is regarded as the maximum flame temperature for hydrogen combustion under standard conditions. The current system eliminates the need for premixing fuel with air, instead allowing fuel and air to mix at the discharge point, specifically at the outlet of the diffuser plate, resulting in a lean fuel mixture. The fuel gas (hydrogen) discharge rate from the diffuser plate is dependent on the gas flow rate, which in turn determines the fuel-to-air ratio, ultimately influencing the flame temperature. The burner assembly (130) efficiently achieves a wide variation of flame temperature (200°C to 700 °C) by efficiently varying the fuel to air ratio that results in achieving wide variation in the operating flame temperature.
