With the deepening of environmental protection, the use of energy-saving and environmentally-friendly gas-fired hot water boilers for central heating has become the norm. According to different user needs and actual working conditions, the configuration of the boiler system is also different, mainly composed of four major systems: combustion system, steam and water system, control system and air and smoke system. Among them, the combustion system includes the furnace, burner, ignition device, etc., and the soda system includes water treatment, feed water pump, sub-cylinder, deaerator, etc. The control system is matched with the boiler control box, and the air and smoke system refers to the flue gas generated by combustion. The system composed of air mainly includes blowers, chimneys and other equipment.

Operating principle of gas hot water boiler

　　Gas boiler room--(high temperature hot water)--heat exchange station--(low temperature hot water)--user--(low temperature hot water)--heat exchange station--(low temperature hot water)--gas boiler room

　　The operating principle of the gas hot water boiler is that the gas and the air delivered by the ventilation system to the furnace are mixed and burned to release heat, which is transferred to the boiler water through each heating surface. After the water temperature rises and completes the heating, the high temperature hot water that meets the heating standard passes through The circulating water pump is sent to the heat exchange station, and the low-temperature hot water after the heat exchange is sent to the residential users through the pipe network at all levels to supply heat through radiation and convection heat exchange. The water flowing through the radiator returns to the boiler for heating, and then flows into the radiator, and so on.

　　The gas boiler system adopts an intelligent control system, which can be fully automatic and safe to operate, easy to maintain, and realize unattended operation.
