Small-volume gas steam generator

Abstract

The utility model discloses a small-volume gas steam generator which comprises a shell, and a heat exchanger is fixed in the middle of the interior of the shell. The steam generator has the advantages that when the steam generator is used, softened water is directly introduced into the heat exchanger to be heated so as to quickly generate steam, and due to the fact that the water introduced into the shell is directly heated in the heating mode, a boiler barrel does not need to be arranged in the steam generator in advance, so that the steam generator is energy-saving and environment-friendly. Therefore, the gas steam generator is smaller in size and more convenient to install and use during use, meanwhile, due to the fact that no boiler barrel is arranged in the gas steam generator of the structure, a large amount of heat cannot be gathered, the risk of explosion of the gas steam generator of the structure during use is avoided, and in addition, the gas steam generator is more energy-saving and environment-friendly. By means of the direct heating mode, the duration of water heating temperature rise, pressure rise and steam output can be effectively shortened while the fuel gas heat is utilized to the maximum extent, and the fuel gas steam generator saves more energy when used.

Description

Technical Field

[0001] The utility model relates to the technical field of steam generators, in particular to a small-volume gas steam generator. Background Art

[0002] Steam generator, also called steam heat source machine (commonly known as boiler), is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. Boiler consists of two parts: pot and furnace. Among the many types of steam generators, fire tube boiler gas steam generator is the most widely used.

[0003] Although the current fire tube boiler type gas steam generator can generate steam by heating water when in use, due to the fact that the fire tube boiler type gas steam generator has a boiler drum inside when in use, the fire tube boiler type gas steam generator is not only large in size when in use, but also not convenient to install and use. In addition, it takes a long time to heat up, increase the pressure, and produce steam during use, and the gas loss cost is high during the preheating process. At the same time, due to the large amount of heat accumulation inside the fire tube boiler type gas steam generator during the heating process, there is a risk of explosion when the fire tube boiler type steam generator is in use.

[0009] By adopting the above technical solution, a controller for realizing coordinated operation of the combustion chamber, the pump and the steam-water separator is integrated in the control box to ensure efficient operation of the gas steam generator.

[0010] Furthermore, the heat exchanger is connected to the shell by bolts, and the combustion chamber is connected to the shell by bolts.

[0011] By adopting the above technical solution, the combustion chamber can ignite the gas mixed with air to generate heat, so as to heat the softened water delivered by the pump by means of the heat exchanger.

[0012] Furthermore, the air inlet pipe and the gas inlet pipe are both connected to the combustion chamber via flanges.

[0013] By adopting the above technical solution, the air inlet pipe can ensure the convenient passage of air into the combustion chamber, and the gas inlet pipe can ensure the convenient passage of natural gas into the combustion chamber.

[0014] Furthermore, the heat conduction cavity of the combustion chamber is connected to the interior of the heat exchanger, and the water supply pipeline runs through the condenser.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In order to solve the problem that the existing fire tube boiler gas steam generator can generate steam by heating water when in use, but because the fire tube boiler gas steam generator has a drum inside when in use, the fire tube boiler gas steam generator is not only large in size when in use, but also not convenient to install and use, and the time for heating, increasing temperature, increasing pressure and producing steam is long during use, and the gas loss cost is large during the preheating and heating process. At the same time, due to the large amount of heat accumulated inside the fire tube boiler gas steam generator during the heating process, the fire tube boiler gas steam generator has the risk of explosion when in use. The utility model directly passes softened water into the heat exchanger when in use. The water introduced into the shell is heated in this heating method to quickly generate steam. Since the water introduced into the shell is directly heated in this heating method, there is no need to preset a drum in the steam generator, which makes the gas steam generator smaller in size when in use and more convenient to install and use. At the same time, since there is no drum in the gas steam generator of this structure, there will be no large amount of heat accumulation, thereby avoiding the risk of explosion of the gas steam generator of this structure when in use. In addition, the direct heating method can effectively shorten the time for heating, increasing the temperature, increasing the pressure and producing steam for water while realizing the maximum utilization of the gas heat, making the gas steam generator more energy-saving when in use.
