Gas fired steam boiler How can I clean it

clean Gas fired steam boiler After a long period of operation, the boiler will inevitably have scale and corrosion problems. The main reason for the formation of boiler scale is that there is hardness in the feed water. After continuous evaporation and concentration at high temperature and high pressure, a series of physical and chemical reactions will take place in the furnace, and finally hard and dense scale will be formed on the heating surface, resulting in reduced heat transfer effect Because of the corrosion under the scale, the heat absorption in the water-cooled fireplace of the boiler will be reduced, and the furnace outlet temperature of the gas-fired steam boiler will increase, which will increase the boiler loss. At the same time, the fouling in the water wall will reduce the heat transfer effect, which may lead to the increase of water wall wall wall temperature and the water wall tube explosion, which will affect the safe operation of gas-fired steam boiler.

Gas steam boiler cleaning steps:
 
The first step: descaling and cleaning: add the prepared descaling and cleaning agent into the circulating water of the cleaning tank according to the proportion to carry out the cleaning and descaling of the gas-fired steam boiler. According to the scale amount, determine the cleaning cycle time and the amount of chemicals added. After confirming that all the scale has been cleaned, the next cleaning procedure will be carried out.
The second step: clean water cleaning. After connecting the cleaning equipment and the gas-fired steam boiler, clean it with clean water circulation for 10 minutes, check the system status, whe
