Although the hot water boilers body is not affected by the pressure of the ring pump, the hot water boiler is always affected by the static pressure of the hot water provided by the high storage tank. The gas hot water boiler has the remarkable features of environmental protection, energy saving, safety and fully automatic operation. It is very convenient to use. In addition, due to the economic operation and government policies, gas-fired hot water boilers are more and more popular.
The higher the floor, the higher the static pressure of the hot water. The diameter of the exhaust pipe installed on the main body of the atmospheric hot water boiler is too small, and the diameter of the exhaust pipe is only ≤ 20 mm. The steam generated in the furnace cannot be quickly discharged, so that the furnace body is subjected to a certain pressure, and there is a certain risk. During the inspection process, when the rated power of the atmospheric pressure hot water boiler is 300,000 kcal and the exhaust pipe of the furnace body is ≤ 20 mm, the steam pressure generated by the furnace can reach 0.15 Mpa due to insufficient exhaust capacity.
The greater the rated thermal power of the boiler, the greater the steam pressure generated in the furnace and the greater the risk. The atmospheric pressure hot water boiler is changed to a steam boiler, and the exhaust pipe connected to the atmosphere of the boiler body is directly installed on the fuel consumption device, the control valve is installed on the exhaust pipe, and the control valve is installed on the exhaust pipe, directly from the exhaust pipe. It is extremely unsafe to let the boiler come out with boiling water or hot water. During the operation of the boiler, if the regulating valve is closed, the atmospheric pressure hot water boiler is prone to explosion under pressurized conditions, and the consequences are unimaginable.
The exhaust pipe connected to the atmosphere on the boiler body is used as a return pipe, so that the boiler body is always in a state of full water pressure. Biomass boilers: horizontal biomass boilers, vertical biomass boilers. Biomass gas heat transfer oil furnace, biomass steam boiler, biomass hot water boiler, biomass heat transfer oil furnace. The function of the gas boiler ignition system is to ignite the mixture of air and fuel. The main components are: ignition transformer, ignition electrode, electric high voltage cable.
A safer ignition system is called an electronic pulse igniter, which is widely used by gas boiler manufacturers such as Energy Saving. It is convenient and time-saving, just press with a finger, and the safety is high, there will be no safety accident due to accidental flameout. Once the flameout state occurs, the control system can close the solenoid valve in time and shut off the gas passage. This closed cycle has two hazards: when the temperature of the furnace water is too high, the generated steam cannot be discharged, the pressure will continue to rise, and explosions and leaks may occur at any time. Second, even if the water temperature of the furnace is not high, a large amount of steam will not be generated, but due to the function of the circulation pump, the boiler body is high under the hot water circulation pressure.
