After a long period of operation,
the boiler plate will inevitably have scale and rust problems. The main reason for the scale formation of the boiler is that it has hardness components in the water. After continuous evaporation and concentration of high temperature and high pressure, a series of physical and chemical reactions take place in the furnace. The reaction finally forms a hard, dense scale on the heated surface.
Sleeping enough damage to the boiler leads to a decrease in heat transfer effect and a decrease in the heat absorption of the boiler water-cooled fireplace due to corrosion factors under the scale. The boiler furnace outlet temperature increases and the boiler loss increases. The scaling effect in the water wall reduces the heat transfer effect, which may cause the water wall wall temperature to increase, causing the water wall to burst, which affects the safe operation of the boiler.
Scale is the main cause of boilers, which is the main cause of boiler accidents. Its hazard is mainly manifested in: wasting a lot of fuel: because the thermal conductivity of scale is only a few tenths of that of steel, so when the surface is fouled by the heated surface The heat transfer will be hindered. In order to maintain a certain output of the boiler, it is necessary to increase the temperature of the fire side, thereby causing heat loss to the external radiation and smoke exhaust.
For the method of boiler cleaning, the
gas boiler can be cleaned by a high-efficiency, environmentally-friendly and non-corrosive cleaning agent. The cleaning agent completely dissolves the scale of the cleaning, so that the equipment tube exposes the primary color of the metal, and reduces the influence of scale and biological algae sludge. At the same time, it has the effect of stripping iron oxide and iron oxide, which can prolong the service life of gas boilers and reduce energy consumption.
