natural circulation steam boiler

Prevention of low temperature hot water boiler condensate corrosion measures what?

1, reduced excess air ratio is reduced boiler flue gas dew point temperature, the main cryogenic preventing corrosion. When reduced from 1.15-1.2 to 1.01-1.02, the dew point temperature of flue gas can be reduced 50-60 ℃. Excess air as possible to reduce the proportion of fuel combusted in a reasonable amount of air, the minimization of SO3.

Electric boiler support a much electricity heating season: Recently, we received a lot of user's message: electric boiler heating season requires a much electricity use? Electricity and our personal interests are closely related, if the boiler into high electricity costs, even if the user bought, did not dare to use long. Fast boiler for everyone a simple calculation that the cost of electricity.

In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving natural circulation steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.

Overpressure caused by boiler, boiler explosion occurred, mostly blind to improve boiler operating pressure or fireman absent without leave, boiler is the result of neglect. Therefore, can not blindly increase the working pressure boilers. Such as the need to improve the working pressure of the boiler must undergo a rigorous technical appraisal departments. In addition, it can be seen from the case of a boiler explosion overpressure, fireman personnel training and the importance of personal responsibility strengthened.
