coal fired 2000 kg steam boiler

Horizontal hot water boiler a few precautions, overpressure accident 1 boiler, coal fired 2000 kg steam boiler overpressure phenomenon of (1) a sharp rise in steam pressure, the pressure exceeds the allowable working pressure gauge pointer over the "red line" is still working pressure safety valve l high. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Second, an accident boiler water, boiler water shortage (1) below the minimum safe water level line, or can not see the water level, the water level gauge glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs. (4) low water interlocking means, the water level should be below a prescribed value blower, Fan, grate reduction motor stops running. (5) a sharp rise in the superheater steam temperature, higher than the outlet steam temperature. (6) boiler exhaust gas temperature rises. (7) the water flow is less than the steam flow, causing Should the water tube due to tube cracking or economizer, an opposite phenomenon occurs. (8) When a serious water shortage, can smell the burnt smell. (9) When a serious shortage, the door can be seen from the red-hot waterwall tubes. (10) a serious water shortage, the furnace tube may rupture, then can hear the explosions, smoke and steam from the door, watching spray the fire door. 2, boiler water treatment (1) through the "waters", sentenced to severe water shortages, emergency shutdown must be prohibited blind to the boiler feed water. (2) through the "waters" sentenced to a slight lack of water, it should reduce fuel blast, the wind, and slowly feed water. Third, full water boiler 1 accident phenomenon (1) above the maximum allowable water level line, or can not see the water level, the water level gauge glass (plate) dark color boiler filled with water. (2) all of the water phase as a color level gauge indication color. High-water alarm signal (3) water level alarm occurs. (4) decreased superheated steam temperature. (5) water flow is not normally greater than the steam flow. (6) water in a large number of sub-cylinder, severe trap operation. (7) with a large amount of water steam severe, increased salinity, water hammer occurs in the sound of the steam pipe, the steam connection flange outwardly dripping take place. 2, steam boiler full of water treatment rinse water table, determined to be minor or serious full of water full of water. Method: Close water table, the water pipe connected cock, then open drain cocks As can be seen from the decreased water level, indicating a slight full of water, the water supply is stopped, the drain valve open, put to the normal water level. Such as severe filled with water due to take emergency shutdown measures.

A bunch of roots of the impact of vertical coal fired 2000 kg steam boiler efficiency: basically all over the country are conducting high-profile coal to natural gas movement, vertical steam boiler use, very large cuts infected micro particles, the same time nitrogen oxides and other toxic gases the smoke has also been suppressed. Vertical steam boiler efficiency is a measure of critical standards, common look behind a pile of roots of the impact of vertical steam boiler efficiency. After investigation authorities, vertical steam boiler heat loss is probably due to include these two: undesirable heat loss and flue gas emissions than adequate combustion air. Emission reduction in heat loss can be retrofitted aft vertical steam boiler exhaust heat recirculation installation, or use more advanced types of condensing boiler.

Steam boiler accident type and processing method, and use common sense safety boiler coal fired 2000 kg steam boiler accident type and processing method, overpressure accident 1 boiler, boiler overpressure phenomenon of (1) a sharp rise in steam pressure, exceeds the allowable working pressure gauge pointer over " red line "safety valve after the pressure is still elevated. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum.

When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Second, an accident boiler water, boiler water shortage (1) below the minimum safe water level line, or can not see the water level, the water level gauge glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs.
