How to adjust the temperature of the steam boiler

In the operation of the steam boiler, the temperature fluctuation will cause some serious problems.the high temperature will lead to the temperature raise of heater wall while the low temperature will result the increase of the gas consumption or even the equipment damage.so it is necessary to regulate the steam temperature.As follows, there are two ways to debug separately:

temperature combustion through combustion regulator

when the load changes, it mainly depends on the temperature adjustment to regulate the temperature.it can be divided into two cases:

1. When the outside load is unchangeable, the fireman can turn up the induced wind and adjust the second air to increase the smoke flue or to improve the furnace temperature to increase steam temperature of the steam boiler.

2.change the combustion intensity through regulating the coal feeder. For example, when the outside load reduced, the pressure and temperature will raise at the same time. At this moment, the pressure and the steam temperature will reduce.

regulate the temperature through temperature reducer

1.contact attemperator directly spray the steam into the feed water and condensate water. In this way, the heat from the heater will be used to heat the steam water and reduce the steam temperature.

2.The temperature reducer of the Coal Fired Boiler is to cool the overheat steam through feed water. When the feed water volume go through the reducer increased, then the steam temperature will reduce.vise versa.
