Chongyang County, Hubei Province since the second half of 2015 to carry out the work out of small coal-fired boilers, non-New 20 tons of steam / hour and below the coal-fired boilers, the full implementation of small coal-fired boilers out of work, with environmental protection, Development and Reform Commission, by letter and other related sector wages, work to strengthen the efforts to promote thorough investigation of strict control to ensure that the county's non-compliance of small coal-fired boilers have all been eliminated remediation. In the specified date (June 30, 2017) completed the small coal-fired boilers out of the task before. Up to now, Chongyang County is not a new coal-fired boilers.
It is understood that, recently, joint quality supervision department of Chongyang County People's Government of Hubei Province, a special selection of personnel to carry out "looking back" activities for the phasing out small coal-fired boilers, special personnel division of responsibilities is based on special teams, focus on examination paper, under chemicals, wine, agriculture, and several other sectors and enterprises of boiler equipment, non-small coal-fired boilers happen "resurgence" phenomenon.
Steam boilers What is the function? Too many in the form of hot sale horizontal steam boilers, 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.
Steam boiler hot sale horizontal steam boiler price Price: works steam boiler is heated in the drum and water is converted into steam, fire gives off heat in the furnace. Qiang boiler plumbing materials sales center is located in the southern suburbs of Datong City, is a design, sales, installation and service of integrated modern enterprise management. The main environmental operating boiler, a steam boiler fired boiler, a heating furnace, steel radiators, cast iron radiators, canned motor pump, the pump piping, air-conditioning water, galvanized pipe, PP board tanks. Details can be found! Works (in Pulverized example) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (excluding the DC furnace), into the separated saturated steam superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 1, the working principle (as an example in pulverized coal fired boilers) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (except for the DC furnace ), the separated saturated steam enters the superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 2. Pulverized coal boiler operation, the position of the center of the flame will affect evaporation. Generally, low center of the flame will lead to greater evaporation, and the high center of the flame will lead to slow evaporation. Also affects the position of the center of the flame superheated steam or reheat steam temperature. Typically, superheated steam, in particular the reheat steam temperature in the lower center of the flame, and vice versa. 3. Pulverized Coal Burner front and rear walls is arranged a thrust manner, tangential firing mode, bis tangential firing methods, each method has its own characteristics. Since the above-described arrangement can not be applied in the same furnace at the same time, the influence of steam can not be directly determined.
A hot sale horizontal steam boiler is an industrial boiler that heats water to a certain parameter and generates high-temperature steam. Water is heated into steam in the drum, and the furnace gives out heat, which is the principle of a steam boiler. Steam boiler belongs to special equipment. Boiler design, processing, manufacture, installation and use must be supervised by the technical supervision department. The user can only use the steam boiler by obtaining a certificate of use of the boiler. According to fuel (electricity, oil, gas), steam boiler can be divided into three types: electric steam boiler, fuel steam boiler and gas steam boiler. According to the structure, vertical steam boiler and horizontal steam boiler can be divided into small and medium steam boilers. Double-return vertical structure and large-scale steam boiler are mostly three-cycle horizontal structure. Steam boiler scale inhibitor is a composite product composed of organic phosphonic acid and polycarboxylic acid, which has high corrosion inhibition and scale inhibition. After washing the gas steam boiler, the water distribution tank becomes the water wall bottom box and the temperature resistance is very good, which can be effectively applied to the water treatment of the low pressure boiler. Gas-fired steam boilers are suitable for corrosion and scale inhibitors, as well as for seawater desalination, distillation and automobile water tanks. The use of scale inhibitors in steam boilers can effectively suppress copper tubes and carbon steel composite components in the process; anti-F E3, Cu 2 accelerates corrosion resistance. The scale inhibitor used in gas-fired steam boiler is the guarantee of the safety of the equipment, it can be easily removed completely and at the same time reduce, the operation is simple, safe and reliable. The scale inhibitor used in gas-fired steam boiler is simple, can be discharged after neutralization, safe and environmentally friendly. It can reduce the use of scale inhibitors to maintain the performance of gas-fired steam boilers, which is conducive to the direct use of users and regular cleaning and maintenance of gas-fired steam boilers, saving equipment maintenance costs. According to the specific operation conditions of gas-fired steam boiler, descaling is simplified and easy to install and operate.
