Description

Technical Field

[0001] The present invention relates to the technical field of boilers, and specifically relates to an oil-gas atmospheric pressure boiler. Background Technique

[0002] A boiler is an energy conversion device. The energy input into the boiler includes the chemical energy in fuel and electric energy. The boiler outputs steam, high-temperature water or organic heat carriers with a certain amount of heat energy. Nowadays, for traditional boilers that burn fuels such as coal, they have gradually been replaced by gas and oil-fired boilers. Because oil and gas boilers have higher combustion efficiency and the flue gas emitted causes less environmental pollution, they are thus advocated and widely used by the government and the public.

[0003] The patent application with the application number CN201811462823.0 discloses a gas-oil boiler. This gas-oil boiler can ensure the dynamic mixing of fuel oil and gas, so as to ensure the heating efficiency. At the same time, it can heat in a centralized manner in different regions, enabling water to form a dynamic cycle and ensuring the output capacity of the boiler.

[0004] When the above equipment is in use, if the combustion stability is too high, resulting in the temperature of the generated water vapor being higher than the temperature tolerance critical value of the next equipment, it will cause damage to the parts of the next equipment, which is not conducive to industrial production. And if the boiler is heated for a long time without controlling the internal pressure of the furnace, resulting in too high internal pressure, there will be a risk of explosion.

The heating pipe penetrates through the box body and extends to the outside of the box body. The purpose of such a setting is to heat the water in the box body by igniting the fuel through the burner to heat the air through the heating chamber and the heating pipe.

[0008] According to the above technical solution, the blowing component includes a blower. One end of the second connecting column away from the support column is fixedly connected with the blower. The air outlet of the blower is fixedly connected with a first air guide chamber. One end of the first air guide chamber away from the blower is fixedly connected with a first air guide pipe. One end of the first air guide pipe away from the first air guide chamber is fixedly connected with the cooling pipe. The bottom of the first air guide chamber is fixedly connected with a second air guide chamber. One end of the second air guide chamber away from the first air guide chamber is fixedly connected with a heat circulation component. The purpose of such a setting is that when the combustion temperature of the device is too high, the temperature inside the first housing will also become high, resulting in a higher air pressure in the heat circulation component than in the air guide pipe, making it easier for the air flow to enter the heat dissipation component, resulting in a slower rate of air discharged from the air outlet pipe, less oxygen in the combustion chamber, and a lower combustion flame, thereby achieving temperature control.

An air outlet pipe is fixedly connected to the bottom of the second cavity. A smoke pipe is fixedly connected to one side of the first cavity.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. By setting the heat circulation assembly, the high-temperature gas generated by combustion in the combustion chamber is used to heat the gas in the second cavity through the heat conduction column, so that the temperature of the gas blown into the combustion chamber is higher than the external temperature, reducing the heat required to heat the gas and improving the utilization efficiency of heat.

[0014] 2. By setting the heat dissipation assembly, when the steam temperature in the air outlet pipe is too high, the baffle will lift, and the gas in the cooling pipe will enter the air outlet pipe to reduce the temperature of the steam in the pipe, so as to realize the temperature control of the exported steam.

[0015] 3. By setting the air blowing assembly, when the combustion temperature of the device is too high, the temperature inside the first housing will also increase, resulting in a higher air pressure in the heat circulation assembly than in the air guide pipe, making it easier for the air flow to enter the heat dissipation assembly, resulting in a slower rate of air discharged from the air outlet pipe, less oxygen in the combustion chamber, and a lower combustion flame, thereby realizing the temperature control.

[0016] 4. By setting the constant pressure head, it is possible to prevent the explosion event caused by excessive pressure in the boiler body during the operation of the boiler. Description of the Drawings
