horizontal wns series gas fired steam boiler

Steam boiler heating in winter north of the advantages and disadvantages of our country, cold weather, heating is essential, often used before coal-fired boilers for heating, but coal-fired boilers to serious air pollution, now gradually replaced by horizontal wns series fired steam boilers. Steam boiler is also very common type of heating equipment, are now gradually penetrate to the south. Steam boiler heating both advantages and disadvantages, we compare: first, an analysis of the advantages of using pulverized coal combustion boiler, the coal is in fact relatively high temperature, the surface temperature of the steam boiler is relatively rapidly increased, but in fact, this system can withstand particularly low cooling system. 2, the steam in the evaporation process, as in fact it is the gas density is quite small, for which the net pressure steam boiler itself is relatively small. 3, the steam itself does not require any external pressure resistance of the propulsion system for it. 4, steam boiler has a clear advantage, the heating effect and very fast, but it stopped gas speed is faster, especially for users of intermittent heating. Second, an analysis disadvantage, during use in a steam boiler, because the pipe is relatively high stability, and is not easy to heat, in the course of prolonged use, the dust around the surface of the device, so that the relatively poor surroundings, and heat slowly dispersed, easy to burn people. 2, in a more simple production conditions, the use of the boiler does not care, and the system will cause leakage particularly large heat loss, so that the waste of energy is relatively more serious. The disadvantage of steam boilers we could have been avoided, in use of the process will be seriously careful to avoid being burned or wasted energy.

Select horizontal wns series fired steam boiler fuel gas of good or good? Steam boiler has a lot of varieties, the most common classification is based on it can be divided into fuel to burn natural gas and electricity and fuel burn of. When buying a steam boiler, a lot of people do not know that we should buy natural gas or fuel steam boiler steam boiler. Gas boilers and oil boilers are our two most common ways the boiler. If you want to use natural gas steam boiler, the need to ensure that there are local gas can be switched on; if you want to use oil-fired boiler, the procurement needs daily oil tank and oil tank buried, placed in position and good design, so that the fuel supply to the boiler. Gas-fired boiler burning natural gas, it has the primary energy saving, high thermal efficiency strengths, oil-fired boiler burning diesel fuel is light, it has a simple fuel reserves by the fuel supplier strengths affect small. The primary operating costs and fuel gas steam boiler steam boiler related with local energy pricing. Per ton of steam vapor is about to use the side 80, if the offer by gas 3 yuan / square to count, that is, 240 / ton operating costs. Steam per ton of about 66kg of light diesel oil is used, if the press 9 yuan / kg fuel offer calculated, then the cost of steam is about 594 yuan / ton. To compare quotes from the fuel, then, natural gas will be cheaper than oil.

What are the overall structure of the boiler boiler structure includes two major boiler and auxiliary equipment. 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. The furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. 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. The main function of the water storage drum, a steam separator, brine and water excluded pot sludge in operation, to avoid the boiler water containing a high concentration of salt 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 order to improve the design and performance assessment, often have to go through boiler thermal balance test. Direct methods to calculate the thermal efficiency of the boiler is called n-efficient use of energy balance, the heat loss from a variety of methods to counter the counter balance called computational efficiency. When considering the practical benefits of the boiler room, boiler thermal efficiency not only look, but also taking into account the energy consumed by the auxiliary boiler. 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. Dust contained in the boiler flue gas (including carbon black and ash), sulfur and nitrogen oxides are air pollutants, which can achieve emissions targets environmental regulations when unpurified indicators several to several tens of times. 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. Flue gas dust removal force used gravity, centrifugal force, inertial force and acoustic adhesion, static electricity and the like. Is generally used for separating coarse particles gravity settling and inertial force, centrifugal separation is often used dust bag filters and electrostatic precipitators having a high dust removal efficiency at higher capacity. Wet venturi - water film adhering water film droplet precipitator ash, high collection efficiency can absorb gaseous pollutants. Since the 1950s, people strive to develop the comprehensive utilization of ash, harm into. The manufacturing cement, bricks and building materials such as concrete aggregate ash. Since the 1970s and from the fly ash cenospheres extracted as a fire-resistant insulation and other materials. Future development will further improve boiler thermal efficiency of boilers and power plants; reduce equipment cost per unit of power boilers and power plants; enhance operational flexibility and level of automation of the boiler unit; develop more varieties to suit different boiler fuel; and improve boiler unit the reliability of operation of the auxiliary equipment; reduce environmental pollution.
