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.
1.Flamelifting caused by a sudden increase of gas pressure;
2.Gas supply disruptions caused by malfunction of solenoid valve;
3.Great gas constituent change and excessive moisture content.
Biomass fuel can be applied to a biomass-fired boiler by treatment and compression molding. Commonly used are straw particles, rice husk particles, wood particles, sawdust particles, peanut rod particles, sugar aldehyde residue particles, palm shell particles and so on.
If the final temperature of feed water doesn’t reach the saturated temperature after being heated by an economizer, (that is, the feed water has not reached the boiling state), we call the economizer as a nonsteaming economizer. Generally, the final temperature is 30-50℃ lower than the saturated temperature.
The dry bottom hopper is formed by bending the lower part of the water wall of the front and rear walls inward. The main function is to gather, cool and automatically discharge ash. It is also convenient for the connection and sealing of the lower header and the ash well.
1. The storage tank is used to store the heat medium oil of the heating system;
2. The storage tank is used to receive the overrunning heat medium oil；
3. The storage tank is used to supplement heat medium oil for the heating system;
4. The storage tank should be placed at the lowest position of the system;
5. A firewall should be placed between the storage tank and the thermal oil heater;
6. The storage tank should be operated at a low liquid level.
Maintenance of the burner: thoroughly clean the rotor plate, ignition device, filter, oil pump, motor and impeller system, and add lubricant to the connecting rod device of air valve. Retest the combustion condition.
Compared with the price of a traditional coal-fired boiler, the operation cost of a gas-fired boiler is relatively high. So, users need to consider the price and quality before purchasing a boiler. For a gas-fired boiler, the energy-saving performance is more important than the boiler price. One year is enough for a gas-fired boiler with good energy-saving performance to save the extra costs of the boiler proper. And, the gas consumption is an important indicator to measure the energy-saving performance of a boiler.
