Steam boiler When should an emergency shutdown when the fired steam boiler cheap kuwait Shanghai encountered the following situations, gas boiler manufacturers need to take emergency shutdown measures: (1) When the steam boiler water level gauge water level drops below the lowest water level, through the "call water when the "law also failed to see the water level. (2) increase the boiler when the water level continued to decline up time. (3) water supply system failure, unable to supply water when the boiler. (4) water level gauge and a safety valve failure, can not guarantee the safe operation of the boiler. (5) When the control valve and the drain valve malfunction when closed lax. (6) when the pressure receiving surface of the waterwall tubes or boiler smoke tubes bulging or cracking occurs, the furnace wall, collapsed down occurs when the front arch. (7) In case of failure of a safety valve, pressure gauge displays the boiler overpressure operation. When by the above situation, should immediately shutdown, should turn off the blowers, the door opened quickly, quick rotation of the grate, the furnace temperature is lowered to withdraw the fire, the coal supply is stopped. When the boiler overpressure, open the emergency vent valve provided on the sub-cylinder is discharged down. When the furnace severe water shortage, should not panic, in order to avoid operational errors. At this time, non-watered furnace. Then reduce oven temperature to find the reasons to be processed.

December 20, "Shanghai Air Pollution Prevention Act," a modified version of issued and published by the Shanghai Municipal People's Congress Standing Committee, with effect from January 1, 2019 came into effect.

Economic information administrative departments should strengthen the guidance jointly with the municipal environment department.

Third, the environment department to determine the emissions of air pollutants key sewage units, must be configured using air pollutant emission-line monitoring equipment, and the environment departments into a unified monitoring network.

Fourth, in addition to coal-fired power plant, the city's ban on new or expanded coal burning, heavy oil, residual oil, petroleum coke, high-polluting fuel (hereinafter referred to as high-polluting fuels) facilities; the construction of coal-fired power plant in accordance with the relevant provisions of Shanghai .

Fangkuai boilers take you to know that horizontal fired steam boiler cheap kuwaits are usually used in a very large number of models, depending on the fuel, the working principle, and the different structures of the boiler itself, which are divided into many different types of boilers, and they are divided into many different types, depending on the fuel, the working principle, and the different structure of the boiler itself. In the case of steam boilers, there are also ordinary boilers and steam boilers, for this horizontal steam boiler, its characteristics are not the same. The boiler arch is made of refractory concrete. The rear arch is low and long, so it burns well. The two-wing flue and side wall brick are made of refractory brick. Boiler front wall, rear wall using universal refractory brick. The air distribution of the grate is reasonable, and the combustion chamber is larger. The applicability of coal is strong. Suitable for all kinds of bituminous coal or anthracite, mixed coal. It burns well. Because the high temperature flue gas first enters the settling chamber and then into the two-wing flue from both sides, and the front smoke box, so the smoke elimination and dust removal effect is good. The water circulation is simple, the compressed parts have reasonable structure and can run safely under the condition of ensuring water quality. The burning equipment is a fast-loading grate. The burning equipment is manufactured and installed in the factory and installed directly on the ground after transportation to the site. It has the advantages of reasonable structure, compact structure and low steel consumption, which makes the boiler's performance, weight and structure size obviously advanced compared with the domestic products with the same capacity. The boiler type is horizontal fast loading water Fire tube boiler, working fluid natural circulation. The boiler heat transfer system consists of a boiler drum, a left and right header, and a water wall. The heating surface is mainly composed of a furnace water wall, a part of the boiler drum and a convection tube bundle in the boiler tube.

Operation of the boiler, including what? Including the operation of the boiler, what does? Following on from the Henan fast boiler company to tell you about: 1. The water level regulation of normal water level in the middle of the gauge (1) of the boiler. Operation with the magnitude of the load is adjusted: to maintain a high level during low load, high load to maintain a low level. Changes should not be down more than 40 mm. (2) to be run on the water level gauge to compare the two groups, if the water level display should be corrected promptly identify the cause. (3) To achieve a balanced continuous boiler feed water, ground water supply, water supply less, to maintain the water level in the normal water level fluctuates slightly in the vicinity. (4) load change is large, prone to false level. Pay attention to judgment, in order to avoid misuse. 2. Steam pressure regulator (1) when the boiler must constantly monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. (2) increasing the boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. (3) boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and to adjust the amount of water. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes. 3. Combustion adjustment (1) combustion index. Normal combustion boiler comprises a uniform supply of the fuel, reasonable ventilation, adjusting three basic aspects combustion. B. maintain a high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100-1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. C. fuel ash to reduce ash content in the combustibles to be below 10%. d. reducing the temperature of the exhaust gas boiler exhaust gas temperature should be controlled below 200 ℃. e. excess air negative pressure holding furnace boiler 1.2-1.4, by adjusting the balance of the blowers to maintain the furnace pressure is 2-3mm. F. to improve the thermal efficiency of the boiler thermal efficiency of the boiler should be kept above 60%. (2) adjusting the combustion a. Reasonable amount and the distribution of fuel to the amount of air needed for combustion. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. b wind principle feature: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. c is the normal combustion conditions: fuel ignition start at 300mm from the shutter of coal, even flames, the fire bed formation, at the end away from the combustion grate at the end of 300-500mm. d. Hold appropriate furnace temperature to avoid coking. E. fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. F. less than 30 minutes residence time of the fuel on the grate. Our company provides services related to the installation of the boiler!
