For a boiler to operate stably and efficiently, all links must be properly coordinated without making mistakes. For gas-fired boilers, it is necessary not only to have softened water treatment facilities, but also to carry out regular sewage discharge, which cannot be ignored.
The automatic boiler water level controller is mainly composed of hardware and software parts to complete the functions of the control system. The hardware part is mainly composed of the water level detection circuit, drive circuit, water level indication circuit, pressure automatic control simulation, manual control, etc. The software part is mainly composed of the programs written in assembly language.
The chain grate is the combustion equipment of coal-fired steam boiler. There are three main types and structures: chain belt grate, scale grate and beam grate.
If the impurities in the boiler feedwater are not dealt with properly, carryover of boiler water into the steam system can occur. This may lead to problems elsewhere in the steam system, such as:
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.
According to the power of water or steam circulation, boilers can be divided into natural circulation boilers, forced circulation boilers, once-through boilers and combined circulation boilers.
In the operation of gas-fired steam/hot water boiler, it need continuous water supply to ensure the water volume in the drum. Once water shortage occurs, it will cause the boiler dry burning problem, which will further result in the boiler failure and other problems.
