8tons Biomass-fired Boiler in Nigeria

The thermal efficiency of 8tons biomass-fired boiler and hot water is more than 88%, and the thermal efficiency of biomass thermal oil boiler is more than 85%. The performance of biomass boiler in thermal efficiency is similar to that of coal-fired boiler, but the pollutants contained in biomass are less, and the fly ash after fuel combustion can also be applied to agricultural fertilizer, and the slag after coal combustion has no use value. At present, with the strict implementation of environmental protection policies, different areas of the boiler pollutant discharge standards are different.

Biomass boiler can burn many kinds of fuel, but belong to the biomass energy class, such as corn stalk, wheat grass, straw, peanut shell, corn cob, cotton stalk, soybean stalk, weeds, branches, leaves, sawdust, bark and other solid waste as raw materials and wood or furniture factory waste materials. Different fuels have certain differences in calorific value. There are two common types of biomass fuels, lumpy and granular. The specific choice of fuel and shape should be determined according to their own production needs.

SZL assembled water tube boiler adopts double drum longitudinal arrangement and chain grate combustion mode. Rated evaporation 4~20t/h. The boiler burns biomass molded solid fuel.
The water wall on both sides of the furnace adopts membrane water wall structure; The water wall pipe of the front and back wall of the furnace extends down to the upper part of the grate to form the front and back arch, which not only increases the sealing performance of the boiler, but also increases the volume of the furnace and the heating surface, and strengthens the strength of the back arch. After the furnace for burning chamber, convection tube bundle, tail economizer. The flue gas enters the tail flue through the furnace, embers chamber, convection tube bundle and economizer, and is discharged into the atmosphere through the dust collector, induced draft fan and chimney. The front wall is arranged with secondary air, controlled by the valve, which is put into use when burning biomass fuel to strengthen combustion, so that the fuel is fully burned out and the combustion efficiency is improved. Higher feed inlet is used to meet the demand of biomass fuel.

Advantages of 8tons Biomass-fired Boiler

1. Fuel advantage, biomass boiler fuel is green, environmental protection, renewable energy, easy to obtain, simple processing technology, the key is inexhaustible and low pollutant emissions.
2. The thermal efficiency of the boiler, the thermal efficiency of the biomass boiler is similar to that of the coal-fired boiler, but from the perspective of pollutant emission and renewable resources, it has an optional place.
3. Low operating cost. The operating cost of biomass boiler is the lowest among the boiler products at present.
4. High degree of automation, the use of digital integrated controller, users can be set in accordance with the program to control the combustion conditions, the operation is very convenient, and you can realize automatic ignition, automatic dust cleaning, and automatic feeding.
5. Ash utilization. Ash after biomass combustion can be recovered and used as potash fertilizer.

The evaporation capacity of 4 tons biomass steam boiler is 4 tons in an hour, and the fuel consumption is 756.89kg. This is for the chain grate boiler, the hand-fired 4 tons of biomass steam boiler is 782.89kg per hour. Due to the process and technology of boiler manufacturers, fuel consumption will be slightly different. If you don’t know how to calculate boiler running costs, please contact us.
