As a kind of equipment that needs to be used continuously for a long time, it is quite common for the boiler to malfunction due to operation errors or environmental quality problems. Today, Let’s discuss the causes, analysis and solutions of common faults of steam boilers.
1) The entire plant may be purchased as a complete package, only needing securing to basic foundations, and connecting to water, electricity, fuel and steam systems before commissioning. This means that installation costs are minimised.
2) This package arrangement also means that it is simple to relocate a packaged shell boiler.
3) A shell boiler contains a substantial amount of water at saturation temperature, and hence has a substantial amount of stored energy which can be called upon to cope with short term, rapidly applied loads.
*This can also be a disadvantage in that when the energy in the stored water is used, it may take some time before the reserve is built up again.
4)The construction of a shell boiler is generally straight forward, which means that maintenance is simple.
5)Shell boilers often have one furnace tube and burner. This means that control systems are fairly simple.
Although shell boilers may be designed and built to operate up to 27 bar, the majority operat
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.
Normally a boiler is provided with two independent sensors for emergency low water level burner cut-outs. So this would never happen. However, if it does, don't take any chances! Shut off the burners immediately!
Before you start raising the level in the boiler you have to find out if any part of the furnace walls has been overheated. If you raise the level over a glowing steel-wall then the boiler might produce more steam than the safety valves can handle and a nasty explosion would be the result.
The boiler gas consumption calculation need the following parameters: gas calorific value and boiler thermal efficiency.
Theoretically, the gas consumption of boiler = boiler thermal capacity ÷ (calorific value of gas x boiler thermal efficiency )
Take the 1 tph steam boiler as an example:
= 600,000 cal / (8500Kcal * 0.98) =72m3/h, the 1 tph boiler's gas consumption per hour is about 72 cubic meters.
