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 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.
Fuel injection nozzle of combustion oil pump of gas boiler does not inject fuel. Possible causes include blockage and leakage of oil supply pipeline. The solution is to clean, repair or replace;
The environmental thermal oil heater has the characteristics of high temperature and low pressure, which can work under lower pressure and produce high temperature.
The environmental thermal oil heater refers to a boiler heated by heat transfer oil. Heat transfer oil, also known as organic heat carrier, has been used as an intermediate heat transfer medium in industrial heat exchange for more than 50 years.
As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm.
The installation contents of boiler body pipeline are as follows:
1) Connection between water supply console and economizer header;
2) Connection between economizer and inlet pipe from economizer outlet to drum;
3) Connection between the main pipe and branch pipe of the drum drop and each lower header of the water wall;
4) Connection of steam guide pipe between each water wall header and steam drum;
5) Connection of superheated steam pipe between outlet header of low-temperature superheater...
