The main purpose of boiler acid washing is to remove iron oxide, copper scale, iron scale and other impurities in the evaporation heating surface of the boiler, and also to eliminate silicon dioxide and scale.
Coking and dust accumulation on heating surface. Whether it is slagging and ash deposition on the water wall of the furnace or ash deposition on the superheater, convection tube bundle, economizer and preheater, the measured thermal resistance of flue gas will increase, and the deterioration of heat transfer will worsen the cooling effect of flue gas, resulting in an increase in the temperature of boiler waste gas.
Boiler safety accessories are indispensable parts of boiler operation, mainly refer to accessories such as pressure gauge, water level gauge, safety valve, steam-water valve, sewage valve, etc. These accessories are extremely important to the safe operation of boilers, especially pressure gauges, water level gauges and safety valves, which are the basic accessories for ensuring the safe operation of boilers. Therefore, they are often referred to as three safety accessories of industrial boilers.
Boiler antifreeze, as its name implies, is a kind of regulator that can prevent the water in the boiler or boiler circulation pipe from freezing and inhibit the formation of scale. Boiler antifreeze contains a special corrosion inhibitor, which can be used and stored for a long time, keeping its characteristics unchanged, and will not damage the metal parts of the boiler.
There are many kinds of industrial boilers, for example, according to the boiler pressure, it can be divided into negative pressure boiler and micro positive pressure boiler.
Different boiler parameters have different requirements on the PH value of boiler water. Generally speaking, the PH value of boiler water is basically between 10 and 12, in some cases, the PH value is between 9 and 11.
