If the impurities in the boiler feedwater are not dealt with properly, carryover of boiler water into the steam system can occur.
Carryover can be caused by two factors:
Three-pass steam boilers are so-called because the combustion gases that are produced inside them in the burner go round a circuit that has three parts before leaving it:
The packaged boiler is so called because it comes as a complete package with burner, level controls, feedpump and all necessary boiler fittings and mountings. Once delivered to site it requires only the steam, water, and blowdown pipework, fuel supply and electrical connections to be made for it to become operational.
Textile is one of the industries that cannot be separated from steam boilers. Whether it is dyeing or drying, boilers can speed up production smoothly. The oil-fired steam boiler is very suitable for textile mills. The oil-fired steam boilers produced by ZOZEN for textile mills mainly include SZS oil-fired steam boilers and WNS oil-fired steam boilers.
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.
Not inspecting it often enough can lead to minor issues being missed, which can lead to major issues later and possibly injury.
Not checking a boiler system could have catastrophic results in the form of a boiler explosion. Fuel may explode due to unfound problems. The high temperatures generated by the boiler can also cause problems if the water level drops too low and the trip switch fails.
If the following three conditions occur during the burning and flame out process of a gas-fired boiler, the furnace is likely to blow up.
1.The residual gas content in the furnace reaches the ignition limit at the start-up phase of the furnace.
2.The fuel content in the furnace reaches the ignition limit after several times failure of ignition.
3.The fuel is sprayed out because of the halfway extinction of the flame. And, the temperature of the furnace can not meet the spontaneous combustion condition of the sprayed fuel. However, the content of the sprayed fuel reaches the ignition limit.
The inlet gas pressure is different for different capacity boiler, for example, the pressure for 2 ton steam capacity boiler is about 8~10KPa, while for 4 ton steam capacity boiler is about 12~25KPa. You can tell us the boiler capacity you want, we will help you to get the gas inlet pressure.
