Main combustion chamber and gasification combustion chamber

(1) Main furnace chamber dimensions: L2200 × W700 × H610 mm (±10%)

(2) The main combustion chamber primarily consists of: phosphate cast modules, refractory castables, high-temperature resistant structural sealant, and thermal insulation materials. The fixed hearth surface of the flat-bed furnace is paved with first-grade high-alumina flat bricks, which remain distortion-free and crack-free even under prolonged high-temperature use.

(3) The primary combustion chamber utilizes renowned R30-R40 main burners, which can automatically adjust their angle during operation. This allows for control over the size of the furnace flame, furnace temperature, and furnace pressure. The burner angle is freely adjustable, enabling fuel consumption control and achieving energy savings and reduced consumption.

(4) 1. A gasification device is installed at the main combustion chamber’s outlet to ensure that any unburned flue gas within the chamber is fully combusted.

2. During the gasification process, unburned flue gas enters the gasification combustion chamber from the main combustion chamber’s outlet. The gasification device processes this gas, ensuring that the resulting flue gas is smoke-free and odorless before discharge.
