Steam boilers What is the function? Too many in the form of plc automatic control 10ton fired industrial steam boiler prices, would like to give a quick four tons of ordinary steam boiler talk. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Let me say a boiler pot. This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. A chain grate combustion section and drive means, coupled with the combustion chamber pan rack on the frame configuration composed of the grate. Four weeks envelope refractories. . From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blast into the lower part of the combustion chamber is a place that boiler greater resistance, need to force the blast. Cinder burn out, through the grate in the rear portion of the olecranon iron discharged from the machine to send out of the furnace slag. The boiler flue gas from the rear, by the front drum smoke tube a return line, the return from the two rear return smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. Not only is the induced draft fan exhaust fumes, the negative pressure of the boiler operation is required. Steam boiler pressure vessels, safety devices is necessary. Boiler necessary water level gauge, pressure gauge, safety valve, thermometer, and under the pressure of the electric pump can pay, and the vapor pump when power is off can also be used. Boiler water must be softened, as well as water treatment equipment.
What is the main danger plc automatic control 10ton fired industrial steam boiler price? The main danger emergency steam boiler 1, surveillance, hazard control boiler steam boiler regular inspection tours, and monitor pressure, water level, temperature and combustion conditions to control the boiler operating conditions. And to take timely measures to ensure safety. 2, the processing operation of the steam boiler in special circumstances: (1) water shortage phenomenon: When the boiler water, the water level below the water table level limits not visible, low water level alarm emits an alarm, bell lights, low interlocking means so that the water level blower, fan, etc. closure operation; boiler exhaust gas temperature rise, a serious lack of water, lake taste top coke production, the door can be seen from the red-hot waterwall tubes, tube deformation or even explosion pipe, can be heard blasting sound, smoke and steam discharged from the door to see the fire door. Treatment: When judged as a serious water shortage, should an emergency shutdown, non-serious water shortage boiler water to the boiler. Immediately stopping the supply of fuel, the wind stops blowing weakened, the front portion of the coal grate furnace Pa, the maximum switch the grate, combustion slag hopper falls quickly, with irrigated off, after extinguishing the fire, stop the wind, open ash door, the door to promote accelerated cooling. Note: Do not feed water to the boiler, shall take measures to prompt blood pressure, prevent the accident, to refrain from watering methods to the furnace fire put out the fire. (2) boiler overpressure phenomenon: a sharp rise in steam pressure, exceeds the allowable working pressure gauge pointer over the "red line", the safety valve, the pressure is still elevated, issued overpressure alarm, steam temperature and steam flow rises cut back. Processing: weakened rapidly burning, manually open the vent valve or safety valve, to increase the water supply, sewage increase (normal water level at this time to keep the boiler), thus reducing the temperature of the boiler water a boiler drum pressure decrease. (3) boiler tube phenomenon: the waterwall tubes blasting significant audible pops or jet sound, until the furnace by the combustion pressure becomes the negative pressure combustion, flue gas and steam and has viewed from the fire door, the door does not close, etc. discharge, although the water supply amount is increased, but difficult to maintain the normal water level and the pressure reduced, the amount of water to abnormally greater than the amount of steam, the exhaust gas temperature decreases, the chimney white smoke, the furnace temperature is reduced, or even extinguished, water flow out of the bottom of the boiler. Treatment: furnace tube rupture is not serious and can maintain the water level when the accident not to expand, may reduce short-term load operation, serious burst pipe and the water level can not be maintained, must be an emergency shutdown. But the wind should not stop, should continue to Sheung Shui, lower wall temperature. Such as: lack of water wall overheating, while burst pipes, emergency shutdown should be prohibited to the boiler feed water, the withdrawal of the furnace over the fire as soon as possible, reducing the furnace temperature, reducing the degree of superheating boiler. (4) steam boilers will produce full of water, such as priming scene of the accident, should take timely and effective measures to eliminate given. (5) boiler operation, in the event when one of the following circumstances, should immediately shutdown :( a) boiler water level below the lowest water level gauge visible edge; (b) increasing water supply and other measures, but the water level continued to decline; (iii ) boiler water level exceeds the highest visible level, the drainage can not see the water level; (iv) to pump all the water system failure or malfunction, not bottled water to the boiler; (e) all of the water table or valve failure; (vi) is set in a stripping all space gauge failure; (vii) damage the boiler element and endanger the safety of operating personnel.
Fangkuai boilers take you to know that horizontal plc automatic control 10ton fired industrial steam boiler prices 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.
