(1) How is the high pressure achieved in a pressurized gasification furnace? What are the viable options? (2) What are the considerations when designing a small pressurized gasification unit? ?
Put simply, high pressure is created by buildup; when pressure increases, the inflow exceeds the outflow, and thus the pressure rises. Once the desired pressure is reached, the inflow and outflow balance each other, maintaining that pressure.
1. The high pressure in the pressurized gasification furnace is increased by gradually raising the gas output and stepping up the set value of the flare control valve to regulate the gas flow. It is necessary to ensure simultaneous increases in temperature and pressure in order to reduce the thermal stress on the equipment caused by temperature rise during pressure increase; therefore, a method of completely holding back the pressure is generally not used. 2. To design a small pressurized gasification unit, it is first necessary to find a company with the qualifications for designing and manufacturing pressure vessels to handle the design work ; At the same time, overpressure protection devices (such as safety valves, rupture discs, etc.) should be designed ; Secondly, the instruments used for measuring pressure, temperature, etc., must meet the required standards, be accurate, and suitable for the production conditions; it is preferable to have an automatic interlock shutdown system ; Also, since gas is being produced, the equipment used, as well as the factories and power supply systems, must meet explosion-proof standards, and there must be fire protection and gas prevention facilities and equipment.
The pressure of the backrest is adjusted by a pressure control system; if there is a pressure load in the rear system, it can be adjusted to a higher level to accommodate that load. If there is no pressure load in the rear system, there is no need to maintain a high level of pressure
