boiler based on steam coal fired

Coal to natural gas operations bunch of factors that vertical pressure steam boiler based on steam coal fired energy consumption indicators of the country are carried out in a big way, the choice of vertical steam boiler, to a large extent minus the pollution of powder, together with nitrogen oxides and other dangerous gases the press has been discharged. Energy consumption indicators is an important rule to measure vertical steam boiler, to discuss the next bunch of factors under pressure vertical steam boiler energy consumption indicators. By analyzing the relevant departments, vertical steam boiler heat loss occurs mainly includes two aspects: the proportion of non-standard sufficient combustion air with exhaust heat loss. Weaken the heat loss can be retrofitted in the vertical steam boiler chimney terminal latent heat of re-use form, or in the selection of better boiler system FGR. Combustion air ratio is not sufficiently decomposed inappropriate criteria: ordinary vertical ejector-type steam boiler burner based, air-fuel ratio can not be formed in the active mobilization. More vertical steam boiler based on a mechanical blower burner, air-fuel ratio due to the following standards several factors: air-fuel ratio standard comprises two situations: when oxygen is excessive, the excess will be an infinite cryogenic air by heat conduction, caused by rising energy vertical steam boilers, low energy consumption vertical steam boiler index; when there is insufficient oxygen, there will not be sufficient to ignite the situation, leading to low energy consumption indicators vertical steam boiler.

Horizontal hot water boiler based on steam coal fired a few precautions, overpressure accident 1 boiler, 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.

Food factory steam boiler based on steam coal fired should be noted that the ignition of the details need to pay attention when the details of the food factory steam boiler steam boiler ignition 1. food plant should be checked (including related accessories, Management) in front of a fire, and water supply. Before entering the water, the drain valve must be closed. Open air valve can discharge the boiler. 2, the treated water is slowly injected into the furnace, the inlet temperature is generally not higher than the boiler 40. When the water level rises to the minimum level of the water table, the water supply valve is closed, the stabilized boiler water level, the water level drops. With particular emphasis before the fire, you should check carefully the coal port and checkpoints in order to improve compliance with strict sealing conditions. Otherwise, it should clear the debris-side sealing surface, and a good gasket insertion, to ensure that meet strict sealing purposes. Since this is a forced air burner, during operation, gas leakage is not allowed, in order to avoid accidents. 3. When food factory fire steam boilers, open the bottom stoker grate and placed on the wood. After all the checkpoints closed, ignite the lighter. After strong fuel combustion, coal began to increase. When coal burning strong, continue to increase coal, closed after a stoker, hermetically sealed, turn the blower, so that coal continues to burn. burn. Strengthen the observation of the fire, the combustion gradually to normal.
