Naturally Circulated Biomass Fired Boiler For Power Plant Or Industry

• Biomass boilers can be classified in horizontal biomass boilers, vertical biomass boilers, biomass gas heat conducting oil furnace, biomass steam boiler, biomass hot water boiler, biomass heat conducting oil furnace.
• Biomass boilers are a kind of boilers. The boilers which use biomass energy as fuel are called biomass boilers. They are divided into biomass steam boilers, biomass hot water boilers, biomass hot air stoves, biomass heat conducting oil boilers, vertical biomass boilers, horizontal biomass boilers and so on.

The boiler adopts the most suitable combustion equipment for biomass fuel combustion -- reciprocating grate.
In the structural design of the boiler, compared with the traditional boiler, the furnace space is larger, and the arrangement of the secondary air is very reasonable, which is conducive to the full combustion of a large amount of volatiles precipitated instantly when the biomass fuel burns.
Boiler can be equipped with fuel (gas) ignition burner, ignition automation.
Boiler feeding, combustion, slag removal, water supply, ignition can use automatic control, very convenient operation.
The boiler is equipped with automatic ash removal device, which can remove the ash on the heating surface of the boiler in time and ensure the efficient and stable operation of the boiler.
The boiler tail is equipped with economizer and air preheater according to user's requirement.
Compared with traditional boilers, boilers have higher efficiency and lower exhaust temperature.
Using efficient insulation materials, boiler surface temperature is low, heat loss can be ignored.
Strictly in accordance with China's national norms and standards of production, all compressed parts are made of high quality boiler steel.
Each boiler is strictly inspected and tested before it leaves the factory, including water pressure test and X-ray inspection.
Manhole, inspection door and fire hole are set for convenient maintenance.
The biggest characteristic of biomass boiler is: energy saving, environmental protection, and easy to install and use.
Fuel supply
The fuel of the boiler is BMF fuel, which is fed into the top hopper by the feeder and then into the furnace by the screw feeder and evenly distributed on the grate.
The combustion process
The fuel is fed into the furnace by a spiral feeder, where it is gradually preheated, dried, on fire, and burned due to the action of high-temperature flue gas and primary wind. In this process, a large amount of volatiles are separated out and the combustion is intense.
After the generated high temperature flue gas scours the main heating surface of the boiler, it enters the coal economizer and air preheater on the heating surface of the boiler tail, enters the dust collector, and finally is discharged into the atmosphere through the chimney.
The ungasified fuel moves towards the back of the grate until it is burnt out, and finally a small amount of ash falls into the slag removal port behind the grate.
Environmental emissions
The ash produced by BMF combustion accounts for about 1.5% of the fuel. To facilitate ash removal, a screw slag extracter is arranged at the back of the boiler to realize continuous ash removal.
The boiler tail flue is arranged with dust remover to ensure that the smoke emission meets the requirements of environmental protection.
Boiler efficiency
Biomass boiler efficiency is generally more than 80%, the boiler model, combustion more fully, the boiler efficiency is higher.
The highest rate reached 88.3 percent, 15 percent higher than the average efficiency of coal-fired boilers
