automatic operation steam boiler

How flue gas condensing boiler condensate Henan excessive treatment? When Henan gas condensing boiler furnace particularly in cold start operation, the heating surface and the rear of the boiler smoke box at the rear often flue gas condensation water generated, so that the boiler stokers mistaken leaking. Henan condensed water generating smoke gas condensing boilers are mainly two reasons: 1 flue gas to condense water vapor at a temperature below the dew point; 2 Henan high gas condensing boiler thermal efficiency, low exhaust gas temperature... Henan gas condensing boiler flue gas temperature slightly higher than the dew point temperature of the flue gas can be economic security operation at rated load, but Henan gas condensing boiler in the case of low load long-running, flue gas temperature is lower than the dew point temperature of flue gas, in this case the condensed water from flowing out of the tail heating surface of the boiler, the boiler is discharged from the smoke box. A German boiler remind you: hot water boiler condensate produced during operation should be promptly eliminated from the boiler, because if excessive accumulation of condensed water will affect the normal operation of Henan gas condensing boiler can cause serious after the smoke box door and smoke box flange connections leaking. Specific measures include: 1 Henan gas condensing boiler condensate outlet is provided in the rear box to smoke condensate water can be discharged, the outlet valve is disposed generally not taken over, seal should be provided to prevent the flue gas from the tube Yi out. 2. smoke box provided to take over the outlet flue gas condensing boiler Henan discharging into the chimney smoke box, because heat is still continued cooling chimney, flue gas water vapor condenses continues in the chimney wall, in the form of small droplets flow down the chimney wall, and therefore should be set to take over the smoke box outlet, the condensed water can be discharged into the trench or any drainage system. Henan flue gas condensing boiler condensate phenomenon should cause too much concern, although the condensed water can not be avoided, but too much condensed water, bound to have a safe operation of the gas condensing boiler Henan have an impact.

The uses of automatic operation steam boiler

Steam boilers are important thermal energy supply equipment in the national economy. Power, machinery, metallurgy, chemicals, textiles, paper, food, and other industries, as well as industrial and civil heating, require boilers to supply large amounts of heat.

The effect of Henan Gas boiler feed water temperature of the boiler in order to improve the thermal efficiency of the entire plant, Henan power plant is equipped with gas boiler feedwater heater, the heater previously referred to pump low pressure heater, after giving the high-pressure pump called heater. By high pressure feedwater heaters, water temperature greatly increased. For example, medium pressure feed water temperature of the boiler mostly heated to 172 deg.] C, the high pressure furnace was heated to 215 deg.] C Usually, ultra-high pressure boiler feed water is heated to 240 deg.] C, sub-critical pressure boiler feed water is heated to 260 ℃. When the high pressure feed water heater due to the leakage of high-pressure heater water splitting in operation through the bypass to the gas boiler. Henan gas boiler feedwater temperature is lowered, the fuel portion of the heat to be used to increase the water temperature. If evaporation unchanged, will increase the amount of fuel, the furnace exit gas temperature and flue gas flow rate must be increased to increase the heat absorption of the superheater, the steam temperature is bound to increase. After Henan gas boiler feed water temperature decreases, assuming the same amount of fuel, since the portion of the heat used to increase the fuel water temperature, reduce the heat to generate steam for the evaporation of time due to the combustion conditions constant, smoke Furnace Outlet constant temperature and flue gas velocity, the superheater heat absorption is not reduced. However, due to the reduced evaporation, steam temperature inevitably increases. Therefore, water temperature decreases, the temperature of the steam will inevitably increase.
