Cleaning of Gas Boilers

Boilers, after prolonged operation, inevitably develop scale and rust issues. The primary cause of scale formation in boilers is the presence of hardness components in the feed water. As it undergoes continuous evaporation and concentration under high temperature and pressure, a series of physical and chemical reactions occur inside the boiler, ultimately forming a hard, dense scale on the heating surface. This reduces heat exchange efficiency and, due to under-scale corrosion, can lead to a decrease in heat absorption by the boiler's water wall, an increase in the outlet temperature of the boiler's furnace, and an increase in boiler losses. Additionally, scaling inside the water wall reduces heat transfer efficiency and may cause the wall temperature to rise, potentially leading to pipe bursts in the water wall, affecting the safe operation of the boiler. Scale is the "root of all evil" in boilers and is a major cause of boiler accidents. Its main危害 is the waste of a large amount of fuel. Since the thermal conductivity of scale is only a fraction of that of steel, the formation of scale on the heating surface hinders heat transfer. To maintain the boiler's output, the fire side temperature must be increased, leading to heat loss through radiation and exhaust. Now, high-efficiency, environmentally friendly, and non-corrosive cleaning agents can be used to clean gas boilers, revealing the metal color of the equipment's tubes, reducing the impact of scaling and biological algae sludge. Additionally, these agents have a stripping effect on iron oxide and sub-oxide, extending the lifespan of gas boilers, reducing energy consumption, and improving productivity. [2]
