cheap gas steam industry boilers
Gas-fired steam cheap steam industry boilers has a positive effect on sustainable development: the increasingly tense in recent years as the price of coal and coal supply more of our day to rise, more and more companies turning to heating gas heating from the traditional gas heating, gas-fired steam boiler heating for its environmental protection, energy conservation in the country has been more widely used, in particular, focus on the most popular heating gas boiler room. From an economic analysis using gas steam boiler operation point of view, generally more than 5 years of small and medium sized gas steam boiler no longer have the value of the Burning gas. Many of our cities in a few years ago began to control the construction of small and medium sized gas steam boiler, the boiler was included within the scope of the demolition basically a longer useful life or the furnace has been out of the product. Be evaluated by the thermal efficiency of a steam boiler and to detect the remaining useful life, with the new gas boiler economic comparison can be seen, simply to change the method of gas fired boilers have undesirable manner by replacing the burner. Gas-fired steam boiler is the ideal replacement for gas steam boiler. Although the thermal efficiency of the fuel steam boiler was also higher, but the smoke pollution in the atmosphere is much larger than gas-fired boiler, steam boiler fuel and there are also issues related to oil transportation and storage, it lost the advantage of long-term development. Gas steam boiler and a steam boiler with gas as compared to the obvious advantages: Since the gas in the ash, sulfur and nitrogen-containing volume is lower than the content of the coal, the amount of dust generated in the flue gas after combustion minimal emissions the flue gas is easier to meet the standards required by the state of combustion equipment, the use of gas-fired boilers can greatly reduce the pollution of the environment. A high intensity gas furnace volume the hot steam boiler, due to the small smoke pollution, a strong convection tubes from corrosion and slagging, heat transfer effect, a large amount of combustion gas triatomic gas radiation, and low exhaust gas temperature, make thermal efficiency improved significantly. Aspect of saving the equipment investment boilers, gas steam boiler furnace may choose a higher thermal load, thereby reducing the volume of the furnace. Heating surface due to contamination, slagging, there is no problem of wear, can use a higher-speed cigarette, to reduce the size of the convection heating surface. Reasonable arrangement convection tubes, so that the capacity of the gas boiler with gas boiler more compact structure, small size, light weight, reduced investment in equipment significantly. Why is it so popular environmental protection boiler
By the end of 2018, Wu'an Municipal People's Government of Hebei Province issued a notice on the issuance of "blue sky Wu'an winning three-year action plan to defend the war", referring to the notification: By the end of 2019, the city has a depth of discharge conditions for reconstruction the coal-fired units completed in-depth treatment, meet the relevant standards. Implementation of coal-fired power management depth. Implementation of coal-fired power plants and coal-fired units emission performance management, emissions of coal-fired units to assess the performance rankings, and resolutely out of shutting down environmental protection, energy consumption, security is not up to 300,000 ten million coal-fired units.
First, the implementation of in-depth treatment of coal-fired power plant
Implementation of coal-fired power plants and coal-fired units emission performance management, emissions of coal-fired units to assess the performance rankings, and resolutely out of shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. 2018, 2019, 2020, respectively, by province and Handan given task given the amount of closed down. Heating demand complete transformation of 600,000 kilowatts grade pure condensing units, high-capacity, high-parameter units accounting for 90%
Special action to carry out deeper cuts power industry, coal-fired units in the original ultra-low emissions, based on the further optimization of operational management, improve pollution control facilities, improving removal efficiency, the implementation of colored smoke plume power plant management. Before the end of 2019, the city has deeper emission coal-fired units to complete the transformation of the conditions of the depth of management, meet the relevant standards.
Second, to carry out special treatment industrial furnaces
The development of industrial furnaces comprehensive remediation plan to carry out an intensive investigation of industrial furnaces, establish classification list management. Stringent emission standards, increase efforts to eliminate non-compliance of industrial furnaces, accelerate the elimination of small and medium gas furnace. Under the premise of resources to implement and encourage industrial furnaces use electricity, natural gas and other clean energy or heat from the surrounding power plant. Ban coal stove, substantially eliminated cogeneration heating pipe network coverage in the range of coal heated oven (furnace); out hearth diameter of 3 m or less gas furnace fuels, natural gas use conditions have temporarily , building a unified center of clean coal gas principle; prohibition blended with high-sulfur petroleum coke.
Pressure cheap steam industry boilerss Products of the non-pressure hot water boiler, also called pressure boilers, boiler usually refers to the top does not bear the water column static pressure of the heating system. That is quite an open hot water tank. Meaning pressure boiler: boiler body opening to the atmosphere. In any conditions, the boiler at the water line are zero gauge pressure boiler. Pressure boilers Model consists of three parts, connected by a hyphen between the parts. Categories: pressure hot water boiler is mainly classified by fuel can be divided into CLDR (CWDR) often piezoelectric hot water boiler, CLHS-YQ (CWNS-YQ) pressure fuel (gas) hot water boilers, pressure coal-fired hot water boilers. Model: The first part of the model by atmospheric pressure boiler code, pot-type code, combustion equipment code, the rated thermal power four sections. Boiler pressure is represented by C code example: CLSG0.35; 95/70; W12 represents a vertical pipe fixed grate boiler pressure, the rated thermal power of 0.35 mW, rated outlet water temperature was 95 deg.] C, the nominal temperature of the water inlet. 70 ℃, burning anthracite class I, a second design of the boiler. Product Structure: The overall structure of pressure boilers and boiler auxiliary equipment including two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. 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.
