coal fired vacuum hot water boiler machine

In the process of cooperation with Lulu, the company has maintained a serious and responsible attitude and enthusiasm, any after-sales problems in a timely manner to communicate and resolve site or through the network. Lulu's relevant person in charge to give us feedback, we buy fast boiler is not only fast because of strong party strength, but also because of the powerful party fast service, any improper operation can get our phone to remind party fast remote monitoring, this allows us to use very reassuring. --customer feedback

Fast boiler manufacturers of coal fired vacuum hot water boiler machine, the heating section combustion Q235 high quality sheet and # 20 steel pipe material, the combustion chamber is sufficiently large, a large heating area, a small furnace heat load; boiler small size, compact structure, and small water capacity, heating speed, it has the following advantages:

Characteristics of hot water boiler described in Henan fast boiler gas hot water boiler with water in vacuo characteristics having different boiling points at different pressures working environment. At normal atmospheric pressure, the boiling point of water is 100 deg.] C, vacuum gas hot water boiler -0.07Mpa working in a pressure range of the water boiling temperature is lower than the corresponding 93 deg.] C, vacuum gas hot water boiler of the boiler to work under pressure. Combustion temperature of the water rises to the boiling temperature of the boiling water produced the same surface temperature steam, which absorb large amounts of heat volatilization. In this case, the water injected into the boiler heat exchanger, the cold water in the steam tube is an outer tube is heated into hot water then flows, steam is condensed out of the cold water cooled tube heat exchanger into water droplets. This completes the process water circulation in vacuo. 1. In the flue tube mounting closed fins increase the heat transfer effect, so that more concentrated arrangement. 2. Integral with a square configuration, personalized spraying, separation shape appearance. 3, large furnaces can techniques: effective to increase the heat radiation per unit area, to reduce NOX emissions. 4. Pure ensure high boiler water boiler water scaling, oxidation. Fives. All wet back shell using tricyclic structure, static heating, large heat balance. 6, all active control system, no staff on duty. Simple pulse level detection circuit unique structure, reliable performance. 8. Out of the water temperature display is doubled, easy to control operation of coal fired vacuum hot water boiler machine and crumb. 9. High quality multilayer centrifugal glass wool insulation, heat losses are small. Vacuum hot water boiler with three gas-pressure safety protection system: automatic safety explosion relief valve: When the pressure inside the boiler continues to rise, the explosion-proof valve due to excessive pressure and burst, releasing the pressure inside the boiler, to ensure the safe operation of the boiler; a digital pressure switch : imported from Japan digital pressure switches, ready disassembly. Detecting the degree of vacuum changes the boiler, when the pressure is too high, the end of fire; explosion-proof valve automatic safety alarm: In special cases, when the pressure in the boiler becomes slightly positive pressure explosion-proof safety valve controlled vibration alarm, turn off the power boiler.

Factors influencing the performance of the vacuum boiler which 1) the boiler body, the valve, the instrument no leaks. At present, including imported equipment, including valves and no guaranteed not to leak occur within three years. 2) Whether the control section has failed, and the negative pressure controller boiler controller will inevitably fail in operation, for example, the failure rate controller made even higher. 3) vacuum pumps, three-way solenoid valve, the device is working properly, because the vacuum pump, three-way solenoid valve does not run often, too easily imported stuck and run. 4) should not be a sudden change in load. Boiler load change is normal. Boilers generally such that 30% to 100% load regulation.
