The main products of our company are oil-fired (gas-fired) boilers, fluidized bed boilers (coal-fired, biomass-fired), pulverized-coal fired boilers, corner-tube boilers (coal-fired, biomass-fired), various types of waste heat utilization boilers for waste and hazardous waste incineration, large intelligent control autoclave and other products. The company has an annual production capacity of more than 10,000 steam tons of boilers and 800 sets of pressure vessels.
1. Different pressures
The atmospheric hot water boiler has no working pressure, and the pressure of hot water in the boiler is always consistent with the atmospheric pressure, and will not change with the change of water temperature; The pressure hot water boiler is equipped with working pressure, and the steam water system is composed of closed vessels and pipes. The pressure changes with the increase of water temperature.
2. Different temperatures
The water temperature of atmospheric hot water boiler generally does not exceed 100 ℃, while the water temperature of pressure hot water boiler can exceed 100 ℃ according to different working pressures.
3. Different structural parameters
The atmospheric hot water boiler has no such strict restriction on its structural parameters. It needs to arrange the heating surface reasonably to ensure reliable water circulation. It has few restrictions on the structure and is flexible and convenient; Pressure boiler has strict restrictions on boiler capacity, parameters, installation position, etc. in structure.
4. Different security
The pressurized hot water boiler has working pressure, which may cause explosion risk. The atmospheric hot water boiler has no pressure, while the atmospheric hot water boiler has no pressure, which is connected to the atmosphere, so there is no explosion risk.
5. Different procedures
The atmospheric hot water boiler does not need to be inspected and accepted by the local quality inspection department. Namely, the boiler can be put into operation after purchase, installation and commissioning. The hot water boiler shall be inspected and accepted by the local quality inspection department, and can only be operated after passing the acceptance.
6. Different water level control
Since the atmospheric hot water boiler is not under pressure during operation, in order to achieve normal pressure operation, the inlet of the circulating water pump is connected with the water outlet of the boiler, the hot water in the boiler is pumped to supply heat to users, the return pipe is connected with the water inlet of the boiler, and the water output of the gas boiler is equal to the water inflow of the system, so there will be water level control problems; There is no water level control problem in the pressurized hot water boiler.
7. Different heating systems
The heating system of the atmospheric hot water boiler is pumped from the boiler by the circulating pump. The water pump is a hot water pump, which is used to overcome the resistance of the system; The heat supply system of the pressure hot water boiler is to send the return water of the pumping system project to the boiler. Generally, the clean water pump is used.
