Different steam pressures correspond to different steam temperatures.
1. The steam temperature of low-pressure boiler is mostly saturation temperature or not higher than 400℃.
2. The outlet pressure of medium-pressure boiler is 3.8 ~ 5.4 MPa, and the commonly used steam temperature is 450℃.
3. The outlet pressure of sub-high pressure boiler is 5.4 ~ 9.8 MPa, and the common steam temperature is 540℃.
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.
The horizontal hot water boiler burner refers to the burner used in the horizontal hot water boiler, which is the most important equipment in the auxiliary equipment of the horizontal hot water boiler.
Make-up water rate refers to the proportion of treated water added to the boilers, steam turbine equipment and its thermal systems and participating in the circulation of steam-water systems in the boiler steam volume in the calculation period.
A hot water boiler should be thoroughly inspected at first, including the accessory pipeline. Close the drain valve and open the gauge cock to discharge the air in the boiler.
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...
Boiler feedwater treatment system includes two parts: pre-desalination system and ion exchange desalination system.
The pre-desalination system includes ultrafiltration system, reverse osmosis system, dosing system, chemical cleaning system, compressed air system, etc.
The ion exchange desalination system includes ion exchange system, acid-base regeneration system, compressed air system, wastewater neutralization treatment system, etc.
The boiler feedwater treatment methods ar...
Generally, small gas-fired hot water boilers are between 0.7 MW and 14 MW, and the output of boilers is different, so the prices are different. Different pressures require different techniques, materials and pressures. The higher the pressure, the higher the price.
