natural gas fired hot water boiler for heating system
Select the gas boiler should pay attention to what matters now gas fired hot water boiler for heating system, gas boiler equipment application can be described as becoming more widespread, mainly because it compared to the more economical use of its electric boiler. Of course, it is precisely because of this advantage it is also a high degree of concern for this problem which brand of gas boiler. In fact, the choice depends on the gas boiler in addition to its brand should also be aware of the following considerations. 1, factory inspection qualified as most people in the choice of products used to be the center of attention on the price and quality of the product, and therefore qualified for manufacturers in the study is that many users purchase a professional gas boiler IMPORTANT often ignored , not knowing choose a qualified boiler manufacturers are also excellent quality of the equipment and an important way to ensure genuine, and this may be some of the documents from the manufacturers should have the qualification certificate as a gas boiler, quality management system certification and special equipment manufacturing license boilers and other very good judgment out. 2, technical consulting In fact, there are some shopping tips when the user selects the gas boiler will be related to technical advice and communicate with the business, in order to better understand the characteristics and advantages of boiler equipment, but many users will find it a nuisance due go directly to the selected gas boiler equipment they need, and this often takes a lot of time and effort, so here do not recommend this practice. 3, after-sale inspection rules In addition, I must mention is also on the sale of gas boilers emphasis on the content, because you can learn from effective content boiler after-sales business can offer each other provided in compliance with the relevant service itself interests, but also to ensure that their rights and interests by the level of detail after-sales service of its investigation and the scope of protection. It should also be noted that more than a few items when the summary content is to remind everyone in the choice of technologically advanced gas-fired boiler equipment, and the benefits of doing so can also help you find users as soon as possible supply professional and efficient gas boiler equipment, so the purchase also hope that these matters can also be brought to our attention.
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 steam boiler, 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.
Foshan Gaoming Liu Ling Textile Dyeing and Finishing Co., Ltd. was founded in 2007, enterprises comprehensive strength, advanced processing equipment, detection means perfect, has a complete quality assurance system, the introduction into a large number of advanced production equipment, to ensure that technical standards and products stable to improve the quality of laid a solid foundation, enjoy a high reputation in the industry. Liu Ling Gao textile company twice with my company were to buy a 20 tons of steam and a whole 10 tons of steam condensing steam boiler fuel gas for the production of textile dyeing and finishing company. Fang fast with strong comprehensive strength and improve the service system to win the favor of the other side, communication from the initial to the final boiler factory-installed square fast all uphold the customer's perspective to think and observe the service concept, for the sake of clever Liu Ling textile companies according to the company's actual demand for textiles, the development of specific programs.
3, fired hot water boiler for heating system fuel
As the name suggests, fuel oil hot water boiler is fuel, including diesel fuel, motor oil, kerosene and other types of fuel. In many areas, higher electricity prices, natural gas is more troublesome, oil is a good choice.
