Biomass Steam Generator Advantages
1. Feeding system: There are double stage feeding system,
The first stage is keep the feeding quantity, which will guarantee the reasonable fuel feeding.
The second stage is to keep that there is no extra fuel inside the feeding rod, which will make the boiler work in safety condition. Meanwhile, it will lower down the load of the feeding systems and avoid any problems.
2. Safety of the boiler
On the second feeding stage, there is spray device which will avoid any back fire problems. During combustion of the boiler, once there is some reason cause the back fire problem, when the temperature of second feeding stage have exceed 95 degree C, the boiler water will be spray to extinguish the fire automatically. Once the temperature lower than 90 degree C, the spray will closed automatically.
3. Control system
We take use of the digital control system which has changed the formal feeding mode( based on motor speed and the time control). We used the air sensor system to control the feeding systems. Based on the concentration of the environment air to control the feeding speed and quantity, which will make the boiler work always in stable condition.
4. Ignition and keep fire.
The ignition system make the boiler start at any time. For some big boilers, there is also keep firing system, which will keep the boiler firing all the time.
5. Maintenance jobs"
You just open the boiler door to clean the dust once per week, that all. Because of the fully combustion, there will be very little dust left inside the furnace.
6. Duct of the boiler
Humanized design of the duct, you can connect very easily in different direction. Which has reduce the elbow of the duct, and increase the flow rate of the air. Through this way the boiler will work stably.
7. Exhaust temperature
There is temperature sensor in the chimney to test the temperature. On that basis, the temperature will be displayed and you will check the exhaust heat temperature will be lower than 120dgree C.
8. Combustion of the boiler
Take use of the higher temperature ceramics combined material burner and different air feeding system, which will the fuel fully burnt. The highest temperature can achieve 1300 degree C, which will make the dust and gas become gasifying in short time.
9. Dust collecting system
There equip with the wet scrubber dust collector for the boiler. The dust collecting efficiency can be more than 99%. Almost all dust will be collected by the scrubber.
Biomass fuels for the Biomass Steam Generator
The advantages of using biomass as fuel:
1.
High calorific value of fuel: Biomass particles have high calorific value, and the calorific value is about 3, 900-4800kcal /kg.
2.
High purity fuel: The biomass particle fuel has high purity and does not contain any other impurities that will consume heat instead of heating, which will directly reduce the cost for the enterprise.
3.
Long service life: Biomass particle fuel does not contain sulfur and phosphorus, does not corrode the boiler, can extend the service life of the boiler.
4.
Green energy clean environmental protection: The biomass particle fuel does not contain sulfur and phosphorus, does not produce sulfur dioxide and phosphorus pentoxide when burning, does not cause acid rain, does not pollute the environment.
