(1)Ensure normal and stable steam pressure, steam temperature and evaporation.
(2)Avoid coking and burner damage; Ensure the safety of the operation of the superheater; Reduce pollution of combustion.
(3)Make the operation achieve the highest economy.
(Question details) specific performance:The gas boiler is powered on, press start, the motor does not turn. Answer: Fault reason:1. Insufficient pneumatic locking.2. The solenoid valve is not sealing, and there is air leakage at the joint. Check the lock.3. The thermal relay is open.4. At least one of the conditional circuits is not valid (water level, pressure, temperature and to check whether the program controller is energized to start). Troubleshooting:1. Adjust the air pressure to the requested value.2. Clean or repair solenoid valve pipe joint.3. Check whether the component is damaged and motor current by reset.4. Check whether the water level, pressure and temperature exceed the limit.ZOZEN gas-fired boiler adopts automatic control to control the operation, combustion, water level, temperature and steam pressure. In case of such problems, the system will automatically prompt the error code.
Proper shutdown procedures are crucial for ensuring the safe and efficient operation of a coal-fired steam boiler. The following steps should be followed when shutting down a coal-fired steam boiler:
1. Reduce the load: Before shutting down the boiler, the load should be reduced to its minimum level. This will help to prevent sudden drops in pressure and temperature, which could cause damage to the boiler and its components.
2. Shut off the fuel supply: The fuel supply to the boiler should be ...
Boiler efficiency refers to the percentage of boiler effective utilization heat to boiler input heat per unit time, that is, the percentage of effective utilization heat per standard cubic meter of gas fuel. ZOZEN gas-fired boilers all adopt large furnace design, with the efficiency as high as 98% and NOx emission as low as 30mg/Nm3.
Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
A boiler economizer (also known as an economizer) are mechanical devices intended to reduce energy consumption or perform a useful function such as preheating a fluid. A boiler economizer is essentially a heat exchanger that makes a system more energy efficient by taking enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler – hence recovering more useful enthalpy and improving the steam boiler’s efficiency.
On a steam raising boiler there are three clear applications for level monitoring devices:
1) Level control - To ensure that the right amount of water is added to the boiler at the right time.
The safety valve of the boiler refers to the valve on the top of the boiler near the boiler control room. The function of the safety valve is to be opened automatically to exhaust the steam and restore the pressure when the boiler pressure exceeds the specified valve, so as to ensure the safety of boiler pressure-bearing components and steam turbines.
