Biomass fired corner tube boiler

Product introduction

Biomass fired corner tube boiler for sale is a natural circulation water-tube boiler which differentiates itself from other water tube boilers by its characteristic water-steam cycle and a pre-separation of heated steam from the steam-water mixture occurs outside the drum and the unheated down-comers. It often used as a biomass corner tube power station boiler.

The corner tube boiler is a kind of new-type chain grate boiler, it has characteristics of compact structure, steel saving, light weight and available to assembly. Biomass fired corner tube boiler for sale is a natural circulation water-tube biomass boiler which differentiates itself from other water tube boilers by its characteristic water-steam cycle and a pre-separation of heated steam from the steam-water mixture occurs outside the drum and the unheated down-comers. It often used as a biomass corner tube power station boiler.
Available fuel: biomass fuel such as bulk straw or stalks, shaped biomass fuel.

Fuel requirement: the size of the fuel should be less than 50*30*10 mm (length*width*thickness) or 30*50 (length*diameter) for clavate fuel with allowing little of those whose length is in the range of 50-100 mm. The total moisture to 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*30*10 mm, while the total moisture should be no greater than 15% within the general requirement.

The features of corner tube biomass boiler:

1.The boiler adopts corner tube pattern, self-supporting structure, problems relating to the expansion and the supporting of corner tube boiler is tackled smartly. Supporting structure is stable and compact.
2. The furnace and the down flow gas duct adopt total welding membrane water cooling wall structure, which has the features of good sealing, less heat losses, and clean.
3. Air pre-heater and economizer adopt case structure that can ensure them be transported in package, to shorten installation period and strengthen the seal ability of the fuel gas duct.
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 can 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 manufacture.
6. The fuel is sprayed to the furnace, which can ensure the layer 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 biomass boiler is only straw or other kinds of biomass material, so the slat of the boiler can be used as fertilizer to agriculture. And it is a high efficiency, energy saving and environmental friendly product.
