A single-stage gasifier is a device that uses coal or coke as raw material, air and water vapor as gasification agents, and performs oxidation and reduction reactions in a fixed bed to produce mixed gas. It can be used in gas-fired or coal-fired industrial kilns in metallurgy, machinery, chemical industry, building materials, refractory materials, ceramics and other industries. Such as heating, baking, annealing, drying, heat treatment, melting and tunnel, push plate, roller table, inverted flame and other kilns.

       Single stage gas generatorThe divisions of the inner fuel layer are: 1. Drying layer; 2. Retort layer; 3. Reduction layer; 4. Oxidation layer; 5. Ash layer.

The gasification reaction of solid fuel is divided into five layers according to the characteristics of the production process in the single-stage gasifier: drying layer - at the top of the fuel layer, the fuel contacts cold coal, and the water in the fuel is evaporated; retorting layer - below the drying layer, because the temperature conditions are similar to the retorting furnace, the fuel undergoes cold decomposition, releasing volatile matter and other retorting products into coke, and the coke is transferred from the retorting layer to the gasification layer for cold chemical reaction; Gasification layer - the gasification process in the gas furnace The main area where the carbon and gasification agent in the fuel undergo intense chemical reactions. In view of the different reaction conditions, the gasification layer can also be divided into an oxidation layer and a reduction layer.
