coalfired steam boiler manufacturer kolkata

Select the gas boiler manufacturers need to consider what is well known that gas-fired boilers and other mining and play in the field or factory ship a crucial role, so that all enterprises should choose high reliability of a gas boiler manufacturers to purchase, in order to use the more convenience to achieve the effect of energy saving. So to choose industry-leading manufacturer of gas-fired boilers to more secure on the device, let me see what points need to be considered below the small series analysis of the specific options: 1: Consider the manufacturers of formal qualifications must first choose a formal nature gas boiler manufacturers, with the production quality to ensure compliance with national standards in the production process. And can better meet the design requirements on the parameters on the use of regular gas boiler manufacturers have the special equipment manufacturing license and boiler production-related documents, is the manufacturer and approved through the state allows the boiler, so choose normality of boiler manufacturers for the purchase of equipment can be more secure. 2: Consider using quality equipment manufacturers choose another gas boiler manufacturers have to understand the configuration parameters of the equipment manufacturers, will be able to directly understand the performance and quality in the use of boiler equipment from the parameters. So be on the configuration parameters of the boiler manufacturing from the comparison determination can achieve the desired quality standards. Professional boiler configuration to meet the standards on the use to reduce the incidence of failure, to measure the quality of equipment can be understood in several ways evaporation and thermal efficiency of the boiler or the rated pressure. 3: Consider manufacturers choose to enjoy a certain reputation in the industry to explain gas boiler manufacturers, not only to better performance on the reputation and product users can get all the recognition in the industry's reputation, because the entire industry to get advanced technology community is united well one of the few manufacturers of praise, fame can enjoy a certain reputation illustrate the considerable strength of the manufacturers in the industry. To sum up, is small as we introduced in selected gas boiler manufacturers need to consider three factors, in addition of course, in addition to the user also needs to be measured from aftermarket manufacturers and equipment prices, and finally choose a reputable supply gas boiler manufacturers for long-term of cooperation in order to guarantee long-term use of the boiler without any worries.

We learned from Zhenjiang Municipal Environmental Protection Bureau, to further promote the Battle of Blue Sky, enhance air quality, the city actively carry out biomass boiler investigation and remediation work has been completed seven bathrooms demolition of straw biomass boiler work in built-up urban area .

Biomass boiler pollution remediation has been a major focus of air pollution control, some of the city bathhouses, hotels, restaurants in the use of raw materials process boilers, illegally blended with coal, waste wood, waste and other substances, not advanced treatment of smoke, nitrogen oxides and other pollutants directly into the atmosphere, some impact on air quality.

According to relevant regulations, Zhenjiang city, the city built the region prohibited the use of straw biomass boilers, the current investigation and the bathroom were 10 straw biomass boiler, in which 7 have been removed, two shutdown ready transformation. At the same time, straw biomass boiler outside the urban area will be completed before the end of June classification renovation work, all dedicated boiler using biomass briquette students, prohibit blended with other fuels, coal, wood, etc., and must complete the construction of the bag efficient dust embodiments, emissions guarantee compliance.

What is the role of environmental protection play a condensing boiler? 1, condensing boiler is a condensing boiler with efficient flue gas condensation waste heat recovery boiler to absorb latent heat from exhaust tail and the sensible heat released by condensation of water vapor, to achieve the purpose of improving the thermal efficiency of the boiler. 2 ,. thermal efficiency condensing boiler Analysis conventional boiler, the exhaust gas temperature is generally 160 ~ 250 ℃, water vapor in the flue gas is still in a superheated state, it can not be condensed into liquid water and release latent heat of vaporization. As we all know, the thermal efficiency of the boiler low calorific value fuel is calculated without considering the heat loss of latent heat of vaporization of fuel in the high heating value. Thus the thermal efficiency of the conventional boiler generally only 87% to 91%. Waste heat recovery boiler is condensed, to which the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat of condensation and sensible heat in the flue gas water vapor. Flue gas-fired condensing heat recovery coalfired steam boiler manufacturer kolkata flue gas volume components typically produce 15% to 19%, the water vapor content of the oil-fired boiler flue gas is 10% to 12%, much higher than in coal-fired boiler water vapor content below 6%. Currently the thermal efficiency of the boiler are low calorific value calculation, although nominally higher thermal efficiency, but because of high natural gas, low calorific value difference of about 10%, the actual energy efficiency to be increased. To take full advantage of energy, reduce exhaust gas temperature, flue gas heat recovery physical, when the wall surface of the heat exchanger flue gas temperature below the dew point temperature, water vapor in the flue gas will be condensed, releases latent heat, low and high 10% calorific value difference can be effectively utilized. [1] 3, economic benefits condensing boiler condensing boiler water temperature of flue gas can be recovered in the boiler and the fuel type and the number of latent heat of steam boiler water using. When the ordinary recovery boiler combustion gas without condensation, the heat efficiency of the boiler if the calculated calorific value of the fuel was 90%, the use of condensing heat recovery unit, the exhaust gas temperature down to 30 ~ 50 ℃, the thermal efficiency will be increased to about 107%. In the case where the fuel consumption is constant, the lower the heating system return, the more condensing heat recovery heat recovery, the higher the thermal efficiency of the boiler. A boiler to provide heat for the winter the water conditioning water ring, which heating hot water temperature is 25 ℃, condensing boiler using a considerable saving than the conventional hot water boiler operating costs. 1 million kcal / h boiler, for example, natural gas consumption of the conventional type boiler 126.5Nm3 / h (natural gas low heat value 8500kcal / Nm3), consumption of natural gas condensing boiler 110Nm3 / h, when the boiler is operating 10 hours a day, heating period is 100 days, then, a condensing boiler using natural gas 16500Nm3 savings per year, using natural gas meter price 1.8 yuan, an annual operating cost savings 29,700 yuan. 4, the role of environmental fuel combustion condensing boiler will produce large amounts of CO2, NOX, and small amounts of SO2, these substances into the atmosphere, causing acid rain and the greenhouse effect, damaging effects on the environment. At the same time water vapor condensing boiler flue gas is condensed, you can easily remove these harmful substances in the flue gas, therefore, use of condensing boiler also important for environmental protection.

Gas boiler must pass quickly ventilated to avoid damage problems because of gas and clogging caused by the emergence; the main components of the gas boiler, or by the ignition system, in order to avoid unexpected flameout, leading to the gas boiler interruption, now computer-controlled gas boiler has been gradually formed, of which there are dozens of computer-controlled process, for some wrong data timely treatment, these have now become the most common way than gas-fired boiler.
