Description

Technical Field

[0001] This utility model relates to the field of protection technology for gas-fired boiler heat exchange equipment, and specifically to a gas-fired boiler heat exchange equipment with protection function. Background Technology

[0002] Gas-fired boilers include gas-fired hot water boilers, gas-fired hot water boilers, and gas-fired steam boilers. Among them, gas-fired hot water boilers are also called gas-fired heating boilers and gas-fired bathing boilers. As the name suggests, gas-fired boilers refer to boilers that use gas as fuel. Compared with oil-fired boilers and electric boilers, gas-fired boilers are the most economical, so most people choose gas-fired boilers as boiler equipment for steam, heating, and bathing.

[0003] A gas-fired boiler heat exchanger is a heat energy conversion device that uses the heat generated by the combustion of gas to transfer heat to water or other working media through a heat exchange process, thereby heating water or generating steam for purposes such as heating, hot water supply, or industrial heating.

[0004] Currently, existing gas-fired boilers cannot clean the furnace before ignition and cannot promptly remove residual gases from the combustion chamber, leading to deflagration during ignition. Therefore, gas-fired boilers include gas-fired hot water boilers, gas-fired hot water boilers, and gas-fired steam boilers.
