What is an atmospheric fixed bed gas generator?

Atmospheric fixed-bed gas generator is a kind of equipment that provides mixed generator gas for thermal processing workshops in machinery, metallurgy, building materials, light industry, chemical industry, refractory and other industries. Atmospheric fixed-bed gas generators are divided into: single-stage gas generators and two-stage gas generators.

The atmospheric fixed-bed gas generator is equipped with a single-bucket lifting coal loader, which adopts double sealed bell cover coal box for automatic coal filling, and uses wet ash tray for automatic slag removal. The grate transmission machinery is all designed outside the furnace body, which is reliable in operation and easy to install and maintain. The gasification of the atmospheric fixed-bed gas generator is carried out under two specific conditions, the gasification process is carried out under atmospheric pressure, and the working pressure is between 3-8kpa, so it is close to atmospheric pressure, so it is called atmospheric pressure.

The material layer accident is stacked on the grate, and the material layer must be maintained at a certain height during the gasification process, which is the so-called fixed layer, and the fixed bed is only relatively fixed.

In fact, the fixed thickness of the material layer is maintained by dynamic coaling and ash production, that is, in the gasification process, while the ash is produced, the material is added at the same time to maintain the relative fixation of the material layer. From a dynamic point of view, the material layer moves from top to bottom, so fixed-bed gasification is also called moving-bed gasification. According to the requirements of the coal quality standard for fixed bed gas generator, there are ten main contents, of course, the minimum quality standard for us to choose coal for gasification is to meet the ten requirements in the standard, if one of the ten requirements is not reached, it is not that it can not be gasified in the furnace, but the furnace condition will deteriorate after entering the furnace, and at the same time it will cause the quality of coal to decline, the coal consumption is large, and it can also cause furnace equipment accidents, and may extend to the purification equipment accidents.

Atmospheric fixed-bed gas generator is a kind of special equipment that uses coal or coke as raw material, air and water vapor as gasifier, and carries out redox reaction in atmospheric fixed-bed to produce mixed gas, which can be widely used in metallurgy, machinery, chemical, ceramic and other industries of various types of gas-fired industrial kilns, such as continuous heating furnaces, annealing furnaces, drying furnaces, tunnel kilns, etc. The atmospheric fixed-bed gas generator has the characteristics of wide application range, fast start-up, high heat conversion efficiency, remarkable environmental protection and energy saving effect, easy operation, etc., the steam generated can be used for the primary air at the bottom of the furnace, and the hot gas produced can be directly supplied to the burner for combustion, which has the advantages of high calorific value, high heat utilization rate, stable heating supply, can improve the heating quality of the workpiece, and improve the operating environment of workers.

Atmospheric fixed-bed gas generator is a patented product gas generator designed in line with the adaptation of industrial kilns in combination with the actual situation of domestic raw coal. Its full name is atmospheric fixed-bed gas generator, which is composed of mechanical feeding system, gas generation system, steam generation system, and slag breaking and slag discharge system. Its structure is simple, the safety is strong, the operation is convenient, the gas produced is mixed semi-water gas, and the calorific value is high; It is integrated with various industrial kilns, making full use of the waste heat of gas, saving energy and reducing consumption.

No smoke, no dust and no noise in the production process; The rotary tower type has strong slag discharge, slag discharge and slag breaking ability, the slag is discharged into the water seal pool, no dust flying, and the raw coal has strong versatility, as long as the raw coal slag nodulation is low, in principle, all coal can be used.

Atmospheric fixed-bed gas generator is a kind of special equipment that uses coal or coke as raw material, air collapse gas and water vapor as gasifier, and prepares for the redox reaction to produce mixed gas in the atmospheric fixed-bed operation, which can be widely used in metallurgy, machinery, chemical, ceramic and other industries of various types of gas-fired industrial kilns, such as continuous heating furnaces, annealing furnaces, drying furnaces, tunnel kilns, etc. The atmospheric fixed-bed gas generator has the characteristics of wide application range, fast start-up, high heat conversion efficiency, remarkable environmental protection and energy saving effect, easy operation, etc., the steam generated can be used for the primary air at the bottom of the furnace, and the hot gas produced can be directly supplied to the burner for combustion, which has the advantages of high calorific value, high heat utilization rate, stable heating supply, can improve the heating quality of the workpiece, and improve the operating environment of workers.
