The calibration method to adjust the valve spring safety valve, remove the lift handle and cover with a wrench and slowly tighten the adjusting screw, coal-fired steam boiler supplier, when transferred to the specified pressure can automatically Exhaust Tighten the screws. Adjustment lever safety valve, first loosen the screws Tuo weight, slowly moving heavy dizzy, when the predetermined pressure to move heavy Tuo automatic exhaust can tighten the captive screws. Coal-fired steam boiler steam load refers to the amount of steam supplied to the outside world. When the change in the amount of steam required outside, the boiler pressure, temperature, level crossing move along. 1, when the steam load increases, the evaporation of the steam boiler is less than the vapor load, will lead to decreased air pressure, water level, for no superheater boilers, coal-fired steam boiler applications, the steam temperature drops as the pressure of the saturated vapor temperature also At the same time decline. Conversely, when the steam load drop, water steam boilers, pressure, temperature will rise. 2, when the load increases, the pressure drops and the water level is low, it should increase the supply and the amount of coal. While enhanced combustion gradually increase to the amount of water, keeping the air and the water level is normal. 3, when the load is decreased, the pressure increases the water level is high, it should reduce the amount of coal and air volume, reduced combustion, then the appropriate amount of water to reduce or suspend the water supply, coal-fired steam boiler classification, air pressure and water level stable rated range, and then the normal combustion and to adjust the amount of water .4, when the load is reduced, the pressure increases when the water level is low, coal-fired steam boilers, should be to increase the amount of water until the water level returns to normal, according to the air pressure change and the load required, the appropriate adjustments to the combustion and water.
