How to choose a fired steam boilers scopes heat exchanger? Steam boiler heat exchangers are generally divided into two categories, one is a direct contact heat exchanger, and the other is an indirect heat exchanger. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. They are used to recover flue gas heat, to achieve energy saving effect of the separation device. In general, conventional steam boiler can be increased by a simple transformation of energy-saving effects, such as increased waste heat recovery installation, which is energy-efficient steam boilers advantage. To promote energy saving is largely the cause of the country, to create more profits for the company, cost savings. Choose a good heat exchanger is one way to achieve energy efficiency goals. Direct contact heat exchanger is a steam boiler with heat recovery and a high ability to remove pollutants in flue gas, but acidic water quality, not easy to use in hot water heating boiler. The so-called indirect heat exchanger, thermal energy means that we recovered from the condensed-called flue gas. Today, more and more people choose to use the steam boiler, the proportion of the market is also increasing. Such steam boiler flue gas discharged contains a large amount of steam, by condensation and release large amounts of latent heat of vaporization. Coal-fired boiler efficiency is much higher than coal-fired boilers. This boiler has a good effect on the selection of the indirect heat exchanger.

Works electric fired steam boilers scopes steam electric boiler refers to water heated to a certain parameter and the production of industrial electric steam boilers high temperature steam, the water in the steam drum is heated to become vapor, the fire in the furnace emits heat, is steam electric steam boilers principle. Electric steam boilers belong to special equipment, design, processing, manufacturing, installation and use of the electric steam boilers must be supervised by technical supervision departments, users only get electric steam boilers use permits to use electric steam boilers. The fuel electric steam boiler (electricity, oil, gas) can be divided into electric steam boiler, electric steam boiler fuel, gas three kinds of electric steam boiler; can be configured in accordance with the electric steam boiler is divided into vertical, horizontal electric steam boiler, small electric steam boilers are mostly single, double the return of the vertical structure, large-scale electric steam boilers and more horizontal structure of three return. A heating device (burner) to release heat, radiation is first absorbed by the water wall heat transfer, vaporization of water boiling water wall, a large amount of steam into the drum for water separation (except the DC furnace), separated saturated steam enters the superheater, by radiation, convection and continues to absorb the furnace top horizontal flue, the flue gases heat the back pass, and superheated steam to reach the required operating temperature. Electric power generation boilers are generally provided with a steam reheater, the steam is used to heat through the high pressure cylinders acting reheater reheat steam go out, the low-pressure cylinder to continue to generate power. Electric steam boiler can be classified according to the electrical power of the fuel steam boiler, electric steam boiler fuel, gas electric steam boiler; can be configured in accordance with the electric steam boiler is divided into vertical, horizontal electric steam boiler, a small electric steam boiler mostly single, double return of the vertical structure, large-scale electric steam boilers and more horizontal structure of three return. Vertical vertical double return configuration electric steam boiler fuel gas burner set under way, double return configuration, fuel combustion, stable electric steam boiler operation; inserted spoiler smoke tube, smoke slow speed, increase heat exchange high thermal electric steam boiler efficiency and reduce user costs. Three horizontal return structure horizontal electric steam boiler shell type three return all wet back downstream pyrotechnic pipe structure, the combustion flame in the combustion chamber large positive pressure, fully extended, low combustion heat load, the high heat of combustion efficiency, effectively reducing the exhaust gas temperature, energy saving, economical use. Waveform threaded pipe and furnace structure, not only improves the strength of the electrical endothermic steam boilers, but also to meet the needs of thermal expansion of the heating surface, scientific and rational, and durable.

In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water boiler to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.

Startup boiler steam temperature does not mention how high do? A: In the unit to start the process, often encounter steam pressure has reached the requirements, and the steam temperature was too much difference, especially in front of the turbine and the blast furnace or red switch occurs. Should take the following measures: appropriate to increase the amount of coal to improve the furnace heat load; adjust the secondary air ratio, increase the amount of lower secondary air; improve wind, air pressure, increased gas velocity; hydrophobic and full of air and exhaust mother pipe in front of the main steam isolation all hydrophobic.
