Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new main specification of boiler equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
■Adopting a unique heating surface layout, boiler corrosion resistance performance enhancements, more secure and more reliable.
Factors influencing the hot water main specification of boiler price fluctuations. On this issue, in fact, need to be considered for many angle, you can try to make some considerations from the following aspects: 1. Different brands and hot water boiler manufacturers and brand manufacturers use technology and production technology for boilers is not the same, so naturally there are differences in the level of prices with different manufacturers and so-called customer word of mouth brand, technology and reputation effects, hot water boiler will. 2. The hot water boiler model, configuration parameters, and auxiliary boiler thermal book most aspects of application in the field of district heating, schools, chemical, and life, then the use of scenarios for different areas of use and boiler tonnage of the selected model, parameters will naturally vary, in addition, out of consideration for the smooth operation of the boiler, safety, purchasing budget, and the use of fuels, auxiliary equipment configuration selected hot water boiler will be high and low ranges, in general imports, the relatively high cost of supporting auxiliary are generally more expensive, naturally affected the price of the boiler. 3. The thermal efficiency and nitrogen oxide emissions of the boiler especially in recent years, with the state limitations on NOx emission standards become more stringent, the different manufacturers began to study new boiler technology, for example, condensation technology, waste heat recovery technology flue gas recycling technologies, application of these techniques, on the one hand to enhance the thermal efficiency of the boiler operation, can provide more heat production units per unit time, on the other hand, also reduces the emission of nitrogen oxides, save the part of the exhaust gas treatment cost, then the use of these technologies, but also make more of a hot water boiler technical input Chen this, the price will be higher, of course, no application will naturally be lower. 4. There is also a factor, and that is the impact of market conditions, different nodes of the time, the degree of saturation of the market will also affect the price of hot-water boilers will be, so the acquisition of the time, also need to understand some of the industry's single boiler prices to different types of boilers, of course, relatively speaking, this is the external factors. In summary, the factors have been set forth hot water boiler part of the price, of course, there are many details of the impact will be, which requires the development of reasonable pricing scheme, detailed analysis, and now, you can probably also visual assessment of these factors up.
Summary terminology main specification of boiler 1, rated thermal power: rated conditions, heat boiler per unit time can be provided, typically expressed in megawatts (MW) or kcal (Kcal / H). ≤1.4MW boiler thermal efficiency, exhaust temperature is not higher than the inlet temperature of the medium 50 ℃. Thermal efficiency> 1.4MW boiler, the exhaust gas temperature not higher than 170 ℃. 2, the cycle of water: boiler water circulation system, the amount of water recycled. Circulating water boiler G = Q * 0.86 * 10 ^ 6 / ΔtQ: boiler thermal power units (MW) Δt: access to water temperature, 3 atm unit (℃): under standard atmospheric pressure at sea level, is 101.325KPa . Pressure: atmospheric pressure higher than normal atmospheric pressure. Vacuum: air pressure below standard atmospheric pressure. 4, heating surface: the surface of the heat transfer medium to absorb heat from the heat medium, such as a boiler furnace, cylinder, pipe, etc.. Radiation heating surface: the radiation heat receiving surface mainly absorbing heat from the heat transfer manner exothermic medium, such as a water wall furnace, the drum abdominal wall. Convection heating surface: mainly convective heat transfer from the high temperature flue gas absorbing manner heating surface of heat, smoke is generally flush heating surface, smoke pipe, convection banks and the like. 5, the thermal efficiency of the boiler: the percentage of the effective use of heat boiler and the fuel consumption per unit time of heat. The higher thermal efficiency, better heat transfer performance. 6, steam quality: cleanliness steam, saturated steam is generally more or less saturated with trace amounts of moisture, with the difference between the steam quality than the standard amount of water. 7, fuel consumption: the amount of fuel consumed by the boiler per unit time. 8, emissions: the amount of sewage discharged boiler blowdown. 9, the natural circulation: relying on the furnace decreased working fluid between the tube and the density difference between the riser furnace actively promote water circulation boiler drum, the drum is recycled back route, the downcomer, the header, the riser pipe, tubing, etc., is introduced soda composition. Forced circulation: boiler water or steam to not only water vapor density difference as a driving force, but also provide some external pump power to circulate in the heating duct. 10, small boilers: water volume ≤50L, and ≤0.7MPa rated steam pressure steam boilers; Rated water pressure does not exceed 0.1MPa water pressure hot water boilers and hot water boilers.
