wns gas fired steam boiler supplier
Bagasse fired wns fired steam boiler supplier is a type of biomass fired steam boiler. Recent years, with the development of the economy, people begin to seek for a healthy lifestyle. Environment protection and sustainable development have become the common sense. Biomass as the fourth largest energy after oil, gas and coal, is becoming more and more popular thanks to its renewable and environmentally friendly. ZG Boiler is the bagasse fired steam boiler manufacturer in China and we can supply customer SZL series bagasse fired steam boiler, DZL series bagasse fired steam boiler and bagasse fired power plant boiler.
Measures to improve the thermal efficiency of the fuel gas-fired boiler wns type of chemical oil-fired boiler which is incomplete combustion heat loss and mechanical incomplete combustion heat loss. Because almost no ash after combustion of the gas boiler, solid and liquid fuels without mechanical incomplete combustion, there is no need to consider the mechanical incomplete combustion of the gas boiler heat loss. In all heat losses, heat losses have tremendous proportions, when the high thermal efficiency of boilers, heat losses so the total loss of the main heat losses of fuel gas-fired boiler flue gas heat loss is the exhaust gas temperature and For air excess factor. When the exhaust gas temperature decreases, high thermal efficiency can be obtained, for example, a conventional three-pass wns fired steam boiler supplier, furnace used in the past straight and smooth smoke tube, must increase the heating surface is arranged to make the exhaust gas to an acceptable degree, the theoretical discharge around the smoke heat loss. Potshell causing significantly increased diameter, wall thickness increased, greatly increased metal consumption, thus further reducing the exhaust gas temperature should be greatly restricted. From the aspect of heat transfer is not only now consider only the heated area, the use of new technology enables heat transfer performance significantly increased, the difference between the heat transfer overcomes the disadvantages of the past performance of the boiler, so that the exhaust gas temperature decreases, the structure is more compact. Center back boiler combustion boiler is preferably small foreign structure, although the two-pass boiler, the heated area is small, but the use of the turbulator charming, the purpose of enhancing the turbulence of the flue gas, disrupt laminar flow boundary wall, reducing the thermal resistance, increasing the heat transfer coefficient, a smaller heating area to achieve the same high thermal efficiency. Lower exhaust gas temperature limit in theory, the exhaust gas temperature can be reduced to very low or even close to the ambient temperature, for maximum thermal efficiency. However, in practice, due to the reduction of the exhaust gas temperature, low temperature corrosion will cause, therefore, the exhaust gas temperature can drop too low, in order to ensure that the wall temperature is higher than the main boiler heating surface flue gas dew point temperature. Therefore, low-temperature corrosion has become a major obstacle to reduce exhaust gas temperature and improve the thermal efficiency of the boiler. Tail auxiliary heating surface increases, further reducing the exhaust gas temperature, fuel gas wns improve thermal efficiency of the boiler as the oil, gas fuel burn easily wns type gas boiler air preheater generally not disposed. The economizer means is a common energy, which can be recycled flue gas was able to effectively reduce exhaust gas temperature. Separation type condensing gas boiler is out of the main boiler heating surface, the installation of the condensing heat exchanger. In one aspect of the flue gas absorption can significantly reduce the smoke temperature, reducing heat losses, on the one hand the absorption of part of the potential condensing water vapor released, increasing the effective use of heat of the fuel. Ash cleaning, to ensure that the heating surface of the scale wns boiler thermal efficiency of the boiler, the presence of soot fouling and heat transfer resistance increases, reducing the heat transfer effect. The thermal conductivity of the scale and soot is almost of the same order of magnitude, with the increase in scale, soot, the exhaust gas temperature rapidly increases, the thermal efficiency is significantly decreased. So, keep the boiler heating surface inside and outside clean, efficient heat transfer, thermal efficiency and to ensure the safe and economic operation of boilers, boiler fuel gas-fired boiler ash cleaning is required.
Gas-fired wns fired steam boiler supplier equipment maintenance equipment maintenance points 1: 1, or twice a day to clean up slag. 2, washed once or twice a heater dust (ash door with the appliance design) weekly. 3, once or twice a month, or butter oil feeding helical gears and bearings induced draft fan. 4, a monthly injection of butter or oil to the fan motor bearings once or twice. 5, a boiler must be 2-4 times the annual emissions (emissions must promptly after filling water). 6, poor water quality, in use. 2. Before, must soften water. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. Daily inspection equipment: 1, the fan regularly checks whether there is a feed screw loosening device, whether there is abnormal noise. 2, regular inspection trip tank float valve is normal replenishment, water pressure is normal. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. 3, if equipped with a pump, replace circulation pump on a regular basis, and check whether the pump is working properly. Function gas boiler the ignition system that ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. 4, regular inspection equipment grounding cable is connected correctly. 5, to ensure the normal supply of fuel in the hopper, so as to avoid non-fuel flameout downtime. 6, it should be observed regularly combustion of the fuel in the combustion chamber. Incomplete combustion of fuel, smoke or large block to form sulfur, the sulfur should be promptly removed block and the governor to adjust the feed flow rate ratio of the fan, to achieve the desired combustion.
Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type boiler paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing wns fired steam boiler supplier for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
