Boiler is a product of our life, and gas boiler is a product of energy saving and emission reduction, which is loved by many customers, but in the use of gas boiler, because of water quality problems, scale will be formed in the boiler. What is the impact of scale on the boiler? The formation of boiler scale
After a long period of operation of the boiler, scale and rust problems inevitably occur. The main reason for the formation of scale in the boiler is that the feed water has hardness components. After continuous evaporation and concentration at high temperature and high pressure, a series of physical and chemical reactions occur in the furnace. Finally, hard and dense scale is formed on the heated surface. Hazard to boilers
It leads to a decrease in the heat exchange effect and due to the corrosion factor under the scale. 2. The heat absorption of the boiler water-cooled wall furnace decreases, and the temperature of the boiler furnace outlet increases, which increases the loss of the boiler. 3. After the scaling in the water-cooled wall, the heat transfer effect decreases, which may lead to the increase in the temperature of the water-cooled wall. The increase in the wall temperature leads to the explosion of the water-cooled wall, which affects the safe operation of the boiler. Scale is the "number one hazard" of boilers and is the main cause of boiler accidents. Its hazards are mainly manifested in: wasting a lot of fuel: Because the thermal conductivity of scale is only one-tenth of that of steel, when the heating surface is scaled, heat transfer will be blocked. In order to maintain the output of the boiler, it is necessary to increase the temperature on the fire side, thereby causing heat loss due to outward radiation and smoke exhaust. Boiler cleaning
The gas boiler can now be cleaned with the most effective and environmentally friendly non-corrosive cleaning agent. The cleaning agent dissolves the cleaned scale, exposing the primary color of the metal in the equipment tube, reducing the impact of scaling and biological algae sludge. At the same time, it has a peeling effect on iron oxide and ferrous oxide, which can prolong the service life of the gas boiler and reduce energy consumption.
