One of the important parts of the boiler - comprising a unitary structure drum boilers and boiler auxiliaries two parts. In the boiler body, the two most important parts of a drum and furnace. We have previously explained before the hearth, and today we take a look at the drum it. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler. Its main function is storage, a water separation, to exclude the water pan and brine sludge in operation, avoiding pot containing a high concentration of salt water and impurities entering with the steam superheater and a steam turbine. Internal drum means comprises a moisture separator and a steam cleaning apparatus, water distribution pipes, sewage and dosing equipment. Wherein the effect of soda is separated from the water wall by means of saturated steam and water to leave, and to minimize the steam carried fine water droplets. Low pressure boiler used as a crude flap and slit baffle separating element; above except pressure in the boiler is widely used for various types of rough separation cyclone, but also with blinds, steel mesh plate or the like are vapor further separation. The drum is also equipped with water gauges, safety valves and other monitoring and protection facilities. In use, the drum often go through thermal balance test, the time to consider the actual benefits of the boiler room, not only depends on the boiler thermal efficiency, energy meter and the auxiliary boiler also consumed. Fuel per unit mass or unit volume of complete combustion, calculated according to the chemical reaction called the theoretical air quantity of air required. In order to have more opportunities to the fuel in contact with oxygen in the furnace combustion, the actual amount of air into the furnace is always greater than the theoretical air amount. While air can be reduced into a multi incomplete combustion heat loss, but the heat losses will increase, also exacerbate corrosion of sulfur oxides and nitrogen oxides generated. We should therefore seek to improve combustion technology, as small as possible in order for the excess air ratio in the furnace so that complete combustion. Times atmospheric pollutants are oxides of dust, sulfur and nitrogen contained in the flue gas of the drum, which can achieve emissions targets Protection index when a predetermined number of times to unpurified. These substances emissions control combustion pretreatment, improved combustion techniques, dust removal, desulfurization and denitration. By means of a high chimney stack can reduce the concentration of pollutants in the atmosphere of the area. Future development will further improve boiler thermal efficiency of boilers and power plants, increase operational flexibility and level of automation of the boiler unit, improve the operational reliability of the boiler unit and auxiliary equipment, which are inseparable from the drum.
The national energy structure adjustment, from coal to gas project forward, is the rapid development and expansion of the square boiler new opportunities across the Group to seize the opportunity, affirmative action, optimize processes, increase R & D efforts, to provide users with high-quality products and services. In recent years, according to the environmental needs of the launch of condensing gas boiler, FGR gas boiler, Ultra Low NOx premix gas boiler, condensing water tube boilers, Ultraten wings hot manufacturer modern commercial heat water boiler technology in the market caused no small response, unanimously users praise. Fast boiler pace of development of the industry attention, which not only benefited greatly enhance quality, quality, brand recognition, but also benefit from the application of innovative technology products, but also reflects the fast Boiler Group's management and technical team building self-improvement and beyond.
With the continuous improvement of hot water boiler equipment R & D technology, gas-fired hot water boiler, which has been introduced in recent years, has been favored by more and more users. This is because the gas-fired hot water boiler has the remarkable characteristics of environmental protection, energy saving, safety and automatic operation, so it has gradually replaced the traditional boiler equipment. In many manufacturers, how to determine the quality of manufacturers has become the most concern of many users. Generally speaking, to determine whether the gas-fired hot water boiler manufacturer is of high quality or not, it is mainly assessed through the following three aspects:
1. Gas-fired hot-water boiler manufacturers that pass the quality of their products usually have outstanding quality advantages over their quality. For example, in order to increase the stability of boiler performance, pure imported gas-fired hot-water boiler burners are selected. Boiler materials are more resistant to high temperature and so on. In addition, the gas emissions of good equipment are within the range allowed by the state, and the enterprises will not be investigated and punished by the state environmental protection supervision department because of the occasional toxic gas exceeding the standard.
2, the strength advantage of the manufacturer obviously wants to determine whether the manufacturer's high-quality users still need to know in many ways the strength of the gas-fired hot water boiler production institution, such as how many boiler workshops are in the factory area and how many boiler testers are equipped. The advanced level of supporting equipment of boiler laboratory, the number of high-end technical personnel and the number and scale of R & D laboratory. Through the detailed understanding of the hardware of this factory, it is judged whether the factory has the ability to produce high-quality gas-fired hot water boiler equipment.
Feedwater temperature decreases, the steam temperature rise but why? In order to improve the thermal efficiency of the entire power plant boiler, power plant boiler feedwater heaters are equipped, the heater previously called feed pump low pressure heater, after giving the high-pressure pump called the Heater. By high pressure feedwater heaters, water temperature greatly increased. For example, medium pressure feed water temperature of the boiler mostly heated to 172 deg.] C, typically heated to a high pressure furnace 215 ℃.
