Can gas hot water boiler be used in the field of heating?

Time : 2021-06-02

Take 10 tons gas hot water boiler as an example, it can output a lot of high temperature hot water every hour, and then through the pipeline to each household, in order to complete heating and hot water supply, it can be said that 10 tons gas hot water boiler is a common heating equipment, used in the field of heating is not suitable.

 

10 tons of gas-fired hot water boiler can meet the heating area of 100,000 square meters, which is a very high number in the whole boiler market.

 

When the gas hot water boiler is started in the hot state, the following matters need to be paid attention to:

(l) The unit is started in the hot state. If the boiler is in the cold state, the boiler's starting operation procedure should be carried out in the cold state slip parameter starting mode.

(2) hot start, steam turbine flushing parameters require that the main steam temperature is 50℃ greater than the inner wall temperature of the high-pressure inner cylinder, and there is 50℃ overheat, but considering the safety of boiler equipment, the main steam temperature should be lower than the rated steam temperature value of 50 ~ 60℃.

(3) when the unit starts, if the boiler has pressure, it should be opened after the ignition of the first and second bypass or to the air exhaust valve.

(4) the reheat steam inlet steam temperature should not be greater than 400℃ : if the primary bypass desuperheater water can not be put into use, the main steam temperature is not higher than 450℃.

(5) Due to the high parameters of hot start, the steam flow should be increased as far as possible to avoid the overtemperature of the tube wall and adjust the combustion.
