The main characteristics of the indicators boiler What? To demonstrate configuration, capacity, parameter and economical operation of the boiler, etc., generally represented by the following indicators to the basic characteristics of the boiler. A) evaporation industrial boilers evaporation is generally 0.1 ~ 65t / h. For the hot fired heating water boiler with a nominal thermal power of its capacity to indicate the size, in units of MW. (Ii) pressure and temperature for saturated steam production boiler, just indicate steam pressure. For the production of superheated steam boiler, the steam temperature of the steam must be marked at the outlet of the superheater, i.e., superheated steam temperature, the unit is deg.] C. For hot water boiler, the hot water temperature has rated outlet and rated the import of sub backwater temperature. With rated thermal power, rated water temperature and the return temperature corresponding to the rated nominal referred circulating water flow of water through the hot water boiler, the unit is t / h. Heating boiler (iii) an evaporator heating surface and the heating surface of the heat generation rate surface evaporation rate or heating rate is an indicator of the intensity of the boiler work, the greater the numerical value, the better the heat transfer, the smaller the amount of metal consumed boiler. Heating surface evaporation rate general industrial boiler is less than 40kg / (m · h); heating surface of the heating rate of hot water boiler is less than 83700kJ / (m · h) iv) the thermal efficiency of the boiler which is an index indicating economical boiler heat, general industrial combustion thermal coal boiler efficiency of around 60% to 82%. Sometimes, in order to measure the heat economy schematically steam boiler, are also commonly used coal or coal water vapor than the ratio expressed as the ratio of the amount of coal in the boiler per unit time over the period of time and the amount of steam production. Coal-water ratio of about the size and type of boiler, coal quality and operation management quality and other factors. Industrial boilers coal-water ratio is generally l: 6 ~ 1: 7.5. Description (a) Evaporation: desired amount of steam produced per hour steam boiler called evaporation, the unit is t / h steam boiler showed that the size of the rated capacity of evaporation, i.e. in boiler design parameters and ensure a certain efficiency. maximum continuous evaporation, also known as the rated output of the boiler (ii) pressure and temperature: the rated pressure steam boiler of the steam at the outlet of the steam or the hot water boiler rated working pressure rated pressure at the outlet of the hot water boiler is called, and He said maximum working pressure, in units of MPa (iii) an evaporator heating surface and the heating surface of the heat generation rate: refers to the heating surface of the pot soft drinks and other heat transfer medium and the flue gas heat exchange area of the pressure receiving member, usually with smoke metal surface area of the gas-side heating area is calculated, in units of square meters. the amount of steam per hour per square meter of the resulting heating surface, called boiler heating surface evaporation rate, in units of kg / (m · h) per hour hot water boiler m² heating surface of heat generated by the heat generation rate is referred to as heating surface, the unit is kJ / (m · h). (Iv) thermal efficiency: thermal efficiency of the boiler is a boiler effective utilization percentage of the heat input and heat boiler per unit time, also called boiler efficiency, [eta] is represented by the symbol.

Heating expert by your side - gas boiler in winter, the weather gradually getting cold up a lot of my friends say this winter is the coldest winter ever, then we do a good job of heating in winter is very important, and because heating in different ways, we now housing complex method of heating can be divided into the following categories: air conditioning heating, radiator heating, geothermal heating, boiler heating, etc., but the most convenient way of these heating air conditioning heating, but compare their heating costs high, radiators and geothermal heating although heating can also be slow but the heating effect, integrating all the advantages of both speed and can save costs in respect of the preferred heating boilers, heating boiler we all know that there are a good variety: the first is coal boiler, because of its low cost is widely used so the effect is very good, but because it will produce a lot of pollution and waste gas after burning garbage, so now banned state environmental protection departments. The second is burning biomass, which is a few years to the increasing popularity of new energy sources, but because of its limitations and is not suitable for urban development. The third is a gas-fired boiler, gas boiler compared to other boiler combustion efficiency can be as high as 95% figure in terms of boiler thermal efficiency is the highest, that is to say that we are saving a considerable part of the cost increase the efficiency of the boiler, and more importantly what is now the city's district basically ventilation gas boiler can be used both for heating and hot water supply, and essentially no pollutants in the combustion process, and more after the garbage is not burned do not have to clean up, it can be described as residential quarters necessary equipment, as well as the most important one is Henan party fast production of gas boiler quality is very high quality, technology and accessories are imported German technology, basic many years will not appear on the quality problems, and virtually save you a lot of maintenance costs. The combination of these characteristics and therefore we propose, as a gas boiler heating experts around us, in full compliance with its title, whether it is housing complex, Business hotel, or administrative units such as the use of gas as a heating boiler facilities do any harm, so do not hesitate direct online order now!
Boiler is how the classification? Press export steam parameters of how to classify? Classification of the boiler is very extensive concept from different angles have different classification, can be classified by application area, according to the export media classification, but also by the pressure of the boiler classification. If the classification parameters according to the steam outlet, then find out which parameters steam boiler, wherein the boiler comprises evaporation, steam pressure, steam temperature etc., and is classified according to the main points of the outlet steam pressure: low pressure boiler (P <2.5MPa ), pressure in the boiler (22.5
