It is necessary to confirm whether the boiler pressure is correspondingly higher when steam is not used and lower when steam is used. This is mainly due to the different water pressure and volume under different pressures.
According to the characteristics of biomass fuel, the biomass boiler produced by ZOZEN Boiler has been specially designed in structure, which has taken the lead in solving the problems such as furnace arch collapse, furnace door burn-out, hopper fire and stopper coking.
There are many kinds of industrial boilers, for example, according to the boiler pressure, it can be divided into negative pressure boiler and micro positive pressure boiler.
The economizer of condensing gas-fired boiler can be installed in the flue of the current CFB boiler, to recovery the energy from the high-temperature flue gas, in order to reduce the fuel consumption. Also, the economizer helps to absorb the air pollutants such as the NOx and sulfur dioxide.
Water quality is of the utmost importance in proper and safe boiler operations. An improperly treated feedwater system can result in the scaling of the boiler internals, safety equipment and auxiliary piping.
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:
To prevent scale formation from low remaining levels of hardness which may have escaped treatment. Sodium phosphate is normally used for this, and causes the hardness to precipitate to the bottom of the boiler where it can be blown down.
