Two - stage gas generator, also known as double - stage gas generator, double - stage gas generator.Due to the addition of an appropriate height and structure of the dry distillation section, the coal in the dry distillation section is slowly heated, low temperature dry distillation, the tar produced will not crack, low tar viscosity, good fluidity.
What are the mandatory requirements for the installation of two-stage gas generator?
1. The main and secondary materials used for site installation must meet the technical requirements specified in the design drawings.Some materials such as welding rod, when the need to pay attention to a few aspects of welding wire, paint, lubricating oil to be strictly moistureproof.Necessary protective measures must be taken when working in damp and low temperature environments.
2. The main workshop of the gas generator, equipment foundation, various reservoirs and other civil engineering projects must be undertaken by the construction team with corresponding construction qualifications.Construction, inspection and acceptance shall be carried out in accordance with the relevant construction and acceptance specifications.
3. Installation of two-stage gas generator equipment and gas pipelines shall be undertaken by an installation team with corresponding installation qualifications.The installation team shall be composed of certified welders, heavy lifting, and a certain number of engineers and technicians and full-time inspectors who shall be responsible for the technical guidance of installation engineering and the inspection, acceptance and safety work during installation.
The gas generator shall install the bottom bearing, and the gas generator shall install the chassis, grate, grate, furnace body, ash basin and small ash knife successively, and finally install the coal machine, drum, oil-pressure thrust system and distribution pipeline.According to the gas generator foundation drawing provided by the manufacturer, draw the installation line to make the foundation and confirm that it has solidified.1. The horizontal tolerance of the bearing lower seat diagram is 0.025mm per meter, and the raceway is taken as the reference for measurement. 2.3. Inject proper lubricating oil into the bearing and rotate freely.
Equipment manufacturing for gas stations:
1. The water jacket of the gas producer (including single-stage type or two-stage type) has atmospheric vessel and pressure vessel.The unit holding the production license of pressure vessel can produce atmospheric pressure, pressure water jacket and steam bag, while the unit holding the production license of pressure vessel can only produce atmospheric water jacket, and other welding equipment shall be made in accordance with the provisions of "Steel Welding Atmospheric Pressure Technical Conditions" (JB2880-81).
2. The production unit must have a workshop with a bridge crane of more than 10 tons, equipped with plate winder (the maximum thickness of plate is 30mm), automatic cutting machine, electric welding machine, special tooling and other production equipment, and a certain number of licensed welders.
3, product manufacturing must be processed according to the drawing, important welding parts must be determined by the welding laboratory welding process, welding by licensed welders, and finally passed the NDT inspection, and issued the product certificate, shipped with the goods.
4. The production of "pressure vessels" must comply with the relevant provisions of "Technical Supervision regulations for Safety of Pressure Vessels" issued by the Ministry of Labor;If there is no national standard for general welding parts, the standards of the ministry (province) and the industry shall be implemented. For newly developed products, enterprise standards shall be formulated and implemented.The enterprise standard shall pass the examination and be put on record in the local technical supervision department.
Construction and installation of coal gas generator gas station:
1. The main workshop, equipment foundation and various storage tanks of the gas generator gas station shall be undertaken by the construction team with corresponding construction qualifications.Construction, inspection and acceptance shall be carried out in accordance with the relevant construction and acceptance specifications.
2. Installation of equipment and gas pipelines of gas generating furnace gas station shall be undertaken by an installation team with corresponding installation qualification.The installation team shall consist of certified welders, experienced lifters, skillful fitters and electricians, and a certain number of engineers and technicians, full-time inspectors and safety personnel, who shall be responsible for the technical guidance of installation engineering and the inspection, acceptance and safety work in the process of installation.
The installation team must be equipped with necessary installation machines and tools (hoisting, welding, plate rolling, cutting, drying box and other equipment) and measuring and testing instruments.
3. The primary and secondary materials used for site installation must meet the technical requirements indicated on the drawings.Some materials, such as welding rods, are strictly protected from moisture.Necessary protective measures must be taken when welding in damp and low temperature environments.
