wood burning steam boiler

Energy saving chain grate SZL 10bar/13bar/16bar/25bar pressure biomass renewable steam boiler


Boiler design features:
1. The high temperature zone can be quickly formed to stably maintain the combustion state of the biomass fuel. The flue gas stays in the high temperature furnace for a long time. After multiple times of filling, the combustion is sufficient, the fuel utilization rate is high, and no black smoke is emitted.
2. Environmental indicators such as soot, carbon dioxide and sulfur dioxide are superior to national emission standards and comply with current international emission reduction policies. The environmental protection department approves such boilers to be used in environmentally friendly areas such as cities.
3. The boiler is continuously burned, the working condition is stable, and it is not affected by the added fuel, which can ensure the combustion efficiency.
4. The mechanical grate adopts uniform air distribution, which is stable in combustion and easy to clean.
5. Biomass boilers are simple, convenient, and require no complicated operating procedures. The boiler starts fast and burns well. After three minutes of starting, there is no smoke in the chimney outlet.
6. The use of new energy is conducive to alleviating energy tensions; fuel adaptability is wide.
7. The combustion equipment produced by the company can be widely used in the transformation of coal-fired boilers and the production of newly-built biomass boilers, which has an excellent market prospect.



Boiler normal operation operation process:

1. Boiler normal working operation

- When the boiler is running stably, the high pressure water supply valve is opened and the water supply starts.
- The air preheater and the flue gas cooler start to work, the feed water is cooled in the air preheater, and then heated by the flue gas cooler to enter the economizer.
- The boiler is operated at no more than the design flow rate and temperature. The turbine outlet pressure of the boiler is not more than 9.2Mpa, and the minimum operating load of the boiler is 40% of the design.


2. Monitoring of biomass fuel combustion

- Grate combustion must be monitored regularly so that the combustion of the fuel in the grate and ash outlet area is fully understood.
- If the fuel on the grate is too small, the ignition will be unstable and the combustion of the fuel will be further hindered.
- If the fuel on the grate is too much, the combustion is not complete, and the furnace is turbulently burned during the vibration of the grate. At this point, low excess air or furnace over pressure can increase the risk of boiler operation.
- When the vibration amplitude of the grate is too large, some fuel will not be burned and will be discharged into the slag discharge port, which reduces the overall thermal efficiency of the boiler.
- If the amount of air in the upper and upper parts of the grate is too large, the flame front on the grate will be too high. This way the flame is mainly concentrated between the middle and the lower part of the grate, and there is very little flame in the upper part of the grate.
- If the oxygen content in the flue gas is too high, it indicates that the fuel supply is too small or the vibration of the grate is too large.
