3.500.000 kcal/h Burner Type Rotary Grate Pre-Furnace for CP Yem

We produced a burner type rotary grate pre-furnace with a thermal power of 3,500,000 kcal/h for CP Yem in Manisa. A pre-furnace is a water-cooled combustion unit that is attached to the front of a liquid or gas-fired boiler, allowing the boiler to operate with solid fuel.

In feed production, heat and steam are mostly used in the conditioning phase of the pellet feed line. The steam supplied to the feed mixture heats and moistens the mixture, facilitating pressing, increasing pellet strength and contributing to hygiene through heat treatment. The economical production of this energy in continuously operating lines is a determining factor on operating costs.

The pre-furnace allows the addition of a rotary grate solid fuel system to existing steam boilers, regardless of its design, and is most commonly used with Scotch type boilers. The cylindrical combustion throat has a water-cooled structure built with curtain pipes; since the walls are constantly cooled, they withstand high temperatures and a significant part of the heat released is transferred directly to the boiler water. The rotary grate behind it provides complete combustion in fuels such as coal and biomass, offering high efficiency and low emissions.
