Boiler after a long period of operation, the inevitable emergence of scale, rust problem, the main reason for the formation of scale boiler water hardness with ingredients, after high temperature, high pressure evaporation and concentration in the furnace after a series of physical and chemical Reaction, and eventually form a hard and dense scale on the heated surface, resulting in reduced heat transfer and corrosion due to scale, which will lead to a decrease of endothermic heat of boiler waterwall furnace, an increase of boiler outlet temperature, and an increase of boiler loss. At the same time, the fouling in the water-cooled wall reduces the heat transfer effect, which may lead to the increase of the temperature of the water-wall wall, which may lead to the explosion of the water-cooled wall and affect the safe operation of the boiler. Scale is the boiler's "Hundreds of first" is the main cause of the boiler accident, its harmfulness mainly manifested in: waste a lot of fuel: Because the scale of the thermal conductivity of only a few one-tenth of the steel, so when the heating surface scaling Will block the heat transfer, in order to maintain a certain boiler output, we must increase the temperature of the fire side, so that the outward radiation and exhaust heat caused by heat loss. Now you can use environmentally friendly non-corrosive cleaning agent to clean the gas boiler, so that the equipment out of the metal tube exposed, reducing the scale and the impact of biological algae sludge. At the same time iron oxide and iron oxide stripping role, can extend the life of gas boilers, reduce energy consumption and increase productivity.
