Diqing in Yunnan Nonferrous Metals Co., Ltd. mainly engaged in Pulang copper mining, site selection, sales and other items. As we all know, in the copper smelting process, it consumes a lot of electricity and thermal power resources, which account for most of the hot water consumption. Combined with the actual demand Diqing company, to provide fast Boiler 1 stage electric heating hot water boiler of 2.1MW.
The working principle of steam boiler 500kws and steam boilers for industrial structural features has brought great convenience, steam boilers led to the development of the times, the following small series to introduce you to the structural characteristics and working principle of steam boilers. Steam boiler is producing steam-based machines, people use a lot, but many of its structure and working principle are not fully aware of, it is the use of volume and pressure water tube steam boilers coal, oil and natural gas are less restrictive , I would like to have a lot of space, but also easy to arrange, in the form of a variety of steam boilers. Water in the steam drum is heated into steam, the heat emitted by the fire in the furnace, is the principle of steam steam boiler. Steam boiler works: 1, heat generated by burning coal in the furnace, the heat transfer by radiation is first absorbed waterwall waterwall Boiling water, a large amount of steam into the drum for water separation (except the DC furnace), separated saturated steam enters the superheater, and continues to absorb the furnace top horizontal flue by means of radiation, convection, heat of the flue gas flue of the tail, and the superheated steam to reach the required operating temperature. Generating steam boilers are generally provided with a reheater, it is used to heat the steam through the high pressure cylinders acting reheater go out of the reheat steam, the low pressure cylinder to continue to generate power. 2, when the pulverized coal fired boiler work, the center position of the flame will impact the amount of evaporation, generally, the lower the evaporation flame kernel, the flame kernel high evaporation amount is small, the center position of the flame will also affect the reheat steam or superheated steam temperature, generally lower the center of the flame in particular superheated steam is then superheated steam temperature to be low, otherwise higher. 3, the arrangement of the burner, pulverized coal fired boiler on, the current embodiment there are opposed wall, more Tangentially combustion, combustion bis Tangentially the like, each have their own characteristics, can not be applied because the same furnace at the same time several above-mentioned arrangement, the steam still can not directly affect the conclusion. Steam boiler structural characteristics: 1, the steam boiler body welding: the main welding using advanced submerged arc welding process, welding quality assurance. All welds were 100% primary radiation detection according to the "Steam Steam Boiler Safety Technology Supervision", according to the eligibility criteria Ⅱ pole. 2, a horizontal steam boiler combustion three return all wet back structure. 3, before steam boiler, after the smoke box sealed with high temperature are graphite asbestos material, a reliable seal, to ensure that the steam boiler flue gas does not leak when run under a slight positive pressure conditions. 4, pipe thread: the second backhaul convection heating surface of the steam boiler, we used a threaded pipe, enabling the efficient heat transfer. Enhanced heat transfer, thermal efficiency of the steam boiler, a threaded tubular light pipe is equal to 2.4. Fluid flow within the tube wall near the fluid flow velocity is very low, the presence of fluid at the wall boundary layer is called, when the thermal resistance in series of several heat transfer water into the flue gas in the outer tube, the boundary layer the maximum thermal resistance, but the boundary layer is thin, as long as the boundary layer of little disturbance, as in an ordinary pressure in a pipe wall to the boss, the disturbance of the boundary layer, will greatly reduce the thermal resistance, is effective threaded pipe one way. 5, to make the system more energy efficient, continuous adjustment using the water supply, to avoid frequent pump start. During the period, the three-pass water smoke tube leaving a wide space, the pot to ensure natural circulation of water flow. 6, the body safety devices: at the rear of the steering steam boiler chamber is provided built-proof door, the steam boiler ignition and running, if the furnace gas deflagration occurs: timely relief, preventing the furnace deflagration, safe and reliable; as built after take-off will not hurt.
Natural gas boiler is a kind of thermal energy conversion equipment, which uses natural gas, liquefied gas, city gas and other gas fuels as fuel to burn the heat released from the furnace, heat the water in the pot, and make it vaporize into steam. Water in a pot (drum) is constantly heated by the burning of gas fuel in the furnace to heat up the temperature and produce pressurized steam. Because the boiling point of water increases with the increase of pressure, the pot is sealed, and the expansion of steam in the boiler is restricted to produce pressure to form a thermal force. Strictly speaking, the steam of a boiler is heated to saturated water and vaporized in the drum at constant pressure. It is widely used as an energy source. Natural gas boiler heating In order to protect indoor warmth and human health, so when choosing natural gas boilers, safety issues are very important, and quality issues can not be ignored, only with good quality, in the use of more assured. Some services can also be done better, the choice of heating is customer satisfaction. Understanding natural gas boilers is certainly a need to know the sales situation of the products, if the natural gas boiler reputation is good, it is still very good in comprehensive aspects, worthy of consumer choice, the conversion of performance and thermal energy can also be consulted. There will be no problems when used like this, and there will be no need to worry about electricity during installation The pressure is not enough. Natural gas boiler shut-down method: after stopping the powder feeder, blow the primary duct for 5 minutes before stopping the oil gun. Oil guns should be blown one at a time, not multiple at the same time. After blowing the gun, ventilate the furnace of natural gas boiler for 5 minutes for 8 minutes, and the air volume is not less than 20% of the rated load. To remove combustible material from the furnace. According to the fuel, natural gas boiler can be divided into natural gas steam boiler 500kw, city gas steam boiler, coke oven gas steam boiler, liquefied petroleum gas steam boiler, etc. According to the structure form, it can be divided into vertical steam boiler and horizontal steam boiler. Natural gas boiler is shell type Full wet backflow three-way pyrotechnic tube structure, flame combustion in large combustion chamber micro positive pressure combustion, complete extension, low combustion heat load, high combustion heat efficiency, effectively reduce the exhaust temperature, energy saving and consumption reduction, use more economical, The heat absorption strength of the boiler is improved by adopting the structure of corrugated furnace tank and threaded smoke pipe, and the heat exchange surface is expanded to meet the need of heat expansion. It is scientific, reasonable and durable.
Steam boiler water treatment equipment What is the role of the boiler itself? Core Tip: boiler water treatment of new fuel gas steam and basic purpose. Well boiler water treatment is an important element to ensure the safe and economic operation of the boiler. Due to the high combustion temperature of the oil, gas. And most of the oil, gas boilers (especially imports of fuel gas-fired boiler) small size, compact structure, higher requirements for water quality, water treatment, if done well, it will cause boiler fouling, corrosion, not only a waste of fuel and easy caused by blocked pipes, burst pipes and other accidents, causing serious boiler will be scrapped biggest economic losses. Therefore, fuel oil and natural gas boilers have to do a good job of the basics of boiler water boiler water treatment.Free Chat
