BFB Solid Fuel Boiler with Front Furnace

The use of solid fuels in boilers for heat and steam production is much more economical than petroleum product liquid fuels. The use of domestically produced coal as fuel or other solid fuels as a by-product from the enterprises will provide an additional income for the enterprise and foreign currency savings for our country.

When it comes to burning solid fuels, boilers designed and manufactured to burn liquid or gaseous fuels are primarily insufficient in terms of combustion volumes.

Front-furnace boilers are used in the production of steam or heat with solid fuels such as coal, chips, wood, sunflower husks, pomace, hazelnut shells, etc.

The front furnace consists of a section of water walls formed by water pipes with pipe-bar-pipe construction. At the bottom of the furnace, there is a grate or combustion system that allows the fuel to burn, and an ashtray or ash removal system under the grate. The furnace is designed and manufactured in such a way that it houses the combustion volume and the grate surface that will ensure the most efficient combustion of the fuel. A large part of the radiation heat generated by the combustion of the fuel is efficiently absorbed by the water walls. Thus, fuel burning becomes efficient and an additional heat transfer and capacity increase to the boiler are provided.

Front furnace’s water pipes are made from high quality steel drawn pipes and are bent and shaped in automatic machines without any deformation.

The outer parts of the furnace are insulated with glass or rock wool to suitable extent and covered with galvanized steel or aluminum sheets of appropriate thickness. The parts that are not insulated are painted with heat and corrosion resistant paint.

In boilers with front furnace, a blind flange burner connection is added in order to connect the appropriate burner which may operate with liquid fuels such as fuel oil, diesel or gaseous fuels such as natural gas and LPG when necessary.
