Generally speaking, biomass fired steam boilers is a kind of biomass boiler, is a steam boiler that burns biomass fuel as raw material. This series of biomass boiler adopts the combustion equipment suitable for biomass fuel combustion – reciprocating grate. In terms of the boiler structure design, compared with the traditional boiler, the furnace space is larger, and the layout of a very reasonable secondary air, which is conducive to the instantaneous precipitation of a large number of volatiles in the combustion of biomass fuel full combustion.
There are many kinds of biomass fuels, such as straw boiler, sugar aldehyde slag boiler, palm shell boiler, etc. in the boiler market. The boiler types are basically the same, but the boiler parameters are different according to the different design fuels. The calculation of fuel consumption of biomass fired boiler is the same as that of gas boiler and coal-fired boiler, which is also determined by boiler efficiency and fuel calorific value.
Especially in terms of fuel calorific value, most of the fuel is used for combustion, and the temperature of various exhaust gases exceeds the condensation temperature of water vapor, so it is impossible to release the condensation heat of water vapor. Therefore, the low calorific value of fuel application is generally used as the calculation basis in energy utilization. Different countries have different choices. Japan and North America are accustomed to using high calorific value, while China, the former Soviet Union, Germany and the organization for economic cooperation and development convert them according to low calorific value, and some of them use both.
Biomass fired steam boilers operation environmental protection, save fuel. It can automatically feed and discharge slag, variable frequency regulation of blower induced draft fan, and automatic operation of boiler. The fuel quantity can be adjusted automatically according to the load change, and the steam output is stable. With pressure, water level, smoke exhaust temperature and other protection and alarm measures to ensure the safe operation of the boiler. The biomass steam boiler is the boiler that society advocates to use, advocate biomass boiler and boiler combustion technology.
The combustion system of this series steam boiler is composed of burners, fans, igniters and other components. The biomass fuel is first preheated in the burner and then transferred to the furnace by a fan for combustion. BMF fuels contain high volatiles, and when the temperature in the furnace reaches the volatiles’ precipitation temperature, the igniter fuel can be ignited and burned rapidly under the condition of air supply. The flue gas after combustion enters the convection flue for heat transfer through the furnace, and then enters the dust collector for purification treatment, followed by discharge to complete the entire combustion and heat transfer process.
The specific operation of biomass fired steam boilers should be carried out according to the product manual to ensure the safety of operators and equipment.
