Corner Tube Biomass Fired Boiler Available fuel include biomass fuel such as bulk straw or stalks, shaped biomass fuel.
Fuel requirements: The size of the fuel should be less than 50 x 30 x 10 mm or Φ30 x 50mm for clavate fuel with allowing little of those whose length is in the range of 50-100mm. The total moisture of the fuel is no greater than 25%, but the max total moisture must be less than 30%. For the pressing shaped fuel, the size of it should be no greater than 30 x 30 x 10mm, while the total moisture should be no greater than 15% within the general requirement.
1.The body adopts corner tube pattern, self-supporting structure, the problem relating to the expansion and the supporting of the boiler is tackled smartly. The supporting structure is stable and compact.
2.The furnace and the descending fuel gas duct adopts total welding membrane water wall structure, which has the features of good sealing, less heat lost and little pollution.
3.Both the air pre-heater and the economizer adopt case pattern structure, which can ensure them be transported in package, so the installation time can be saved and seal ability of the fuel gas duct is strengthened.
4.There is flag pattern heating surface before the high temperature super heater, so the high temperature ability of the super heater can be ensured, meanwhile, the super heater van be operated in the serious fuel gas environment stably.
5.The cross girder grate is adopted, so it has the features of less operation resistance, better grate cooling effects, lower breakdown rate, less fuel leak. And the grates are made by the first-class professional manufacturer.
6.The fuel is sprayed to the furnace, which can ensure the straticulating combustion and suspending combustion, thus the combustion efficiency is enhanced.
7.It adopts sectional boiler setting so that the total weight of the boiler is lighter.
8.The fuel of this boiler is only straw or other kinds of biomass material, so the slag of the boiler can be used as fertilizer to agriculture. And it is a high efficiency, energy-saving and environmental-friendly product.
