Although the boiler body is not affected by the pressure of the ring pump, the boiler is always affected by the static pressure of the hot water provided by the high storage tank. Gas-fired hot water boilers are environmentally friendly, energy-saving, safe, and fully automatic operation. They are very convenient to use. In addition, due to economic operation and government policy encouragement, 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 some exhaust pipes is only ≤20 mm. The steam generated in the furnace cannot be quickly discharged, which makes the furnace body bear a certain pressure, and there is a certain risk. During the inspection process, it was found that when the rated power of the atmospheric hot water boiler is 300,000 kcal and the exhaust pipe of the furnace body is ≤20 mm, the steam pressure generated in the furnace can reach 0.15 Mpa due to insufficient exhaust steam capacity.
The greater the rated heating power of the boiler, the greater the steam pressure generated in the furnace, and the greater the risk. The normal pressure hot water boiler is changed to a steam boiler, that is, the exhaust pipe connected to the atmosphere of the boiler body is directly installed on the steam consumer, and the control valve is installed on the exhaust pipe. There are also control valves installed on the exhaust pipe. Bathing with boiling water or hot water from the boiler is extremely unsafe. During the operation of the boiler, if the regulating valve is closed, the atmospheric 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 and pressure. Biomass boilers: horizontal biomass boilers, vertical biomass boilers. Biomass gas heat conduction oil furnace, biomass steam boiler, biomass hot water boiler, biomass heat conduction oil furnace. The function of the gas boiler ignition system is to ignite the mixture of air and fuel. Its main components are: ignition transformer, ignition electrode, and electric high-voltage cable. A safer ignition system is called electronic pulse igniter, which is widely used by gas boiler manufacturers such as Zhuoyi Energy Saving. It is convenient and time-saving. It only needs to be pressed with a finger, and has high safety. There will be no safety accidents due to accidental flameout. Once the flameout occurs, the control system can close the solenoid valve and shut off the gas passage in time. This kind of closed loop has two hazards: when the temperature of the boiler water is too high, the generated steam cannot be discharged, the pressure will continue to rise, and explosions and leakage accidents may occur at any time. The second is that even if the furnace water temperature is not high, a large amount of steam will not be produced, but due to the action of the circulating pump, the boiler body is very high under the hot water circulation pressure.
