How to improve the thermal efficiency of gas steam boiler?Find the right key points!

When the gas steam boiler is running, a series of chemical and physical reactions will occur in the furnace. In the process of use, hard and dense scale will be formed on the heating surface, which will directly lead to the reduction of the heat exchange efficiency of the boiler.And because of the corrosion under the scale, the water wall furnace heat absorption of the gas steam boiler will be reduced, thus reducing the thermal efficiency and wasting the input cost.

 

Therefore, it is imperative to improve the boiler thermal efficiency and clean up the boiler scale!

 

There is a need to clean up scale, that is to let the boiler run for a long time.

 

The thermal conductivity coefficient of scale is only one percent of steel. Once the heating surface is scaled, the heat transfer effect will be hindered. In the process of use, in order to maintain a certain output of the boiler, the temperature of the fire side must be increased.In the process of increasing the outlet temperature of the furnace of the gas steam boiler, it will increase the loss of the gas steam boiler. After scaling in the water-cooled wall of the equipment, it will effectively reduce the heat transfer effect. It is very likely to lead to an increase in the temperature of the water-cooled wall tube leading to the water-cooled wall tube explosion.

 

Cleaning the boiler becomes particularly important.In the process of cleaning, efficient, environmentally friendly and non-corrosive cleaning agents can be selected, which will expose the original metal color of the equipment tube and reduce the influence of scaling.

 

Secondly, the gas steam boiler in the ignition, need to pay attention to observe the furnace smoke temperature and the main steam temperature change;When the main steam pressure is in the state of rise, if the boiler ignition, smoke temperature rise speed will be significantly slower or not rise, to immediately check the oil gun fire situation.
