boiler company list in all over india
In the boiler company list in all over india, the exhaust temperature is between 160 ℃ and 250 ℃, and the steam in the flue gas is still in the overheated state. It is impossible to condense into liquid water and give out the latent heat of vaporization. It is well known that the boiler thermal efficiency is calculated by the fuel low calorific value without considering the heat loss of vaporization latent heat in the fuel high calorific value. As a result, the thermal efficiency of conventional boilers can only reach 87% / 91%. The condensing waste heat recovery boiler reduces the exhaust temperature to 50 ℃ and 70 ℃, which fully reclaims the sensible heat in flue gas and the latent heat of condensation of water vapor. Recovery of steam volume in boiler flue gas by condensing waste heat using natural gas as fuel At 15%-19%, the steam content in the flue gas of the oil-fired boiler is 10%-12%, which is much higher than that in the flue gas of the coal-fired boiler, which is less than 6%. At present, the boiler thermal efficiency is calculated by low-level heat generation. Although nominal thermal efficiency is high, because of the high natural gas, the difference of low-level heat-generating value is about 10%, the actual energy utilization rate still needs to be improved. In order to make full use of energy, reduce the exhaust temperature and recover the physical heat energy of flue gas, when the wall temperature of the heat exchanger is lower than the dew point temperature of the flue gas, the steam in the flue gas will be condensed and the latent heat will be released. 10% of the high and low calorific difference can be used effectively.
Gas boiler company list in all over india is conveyed to the fuel pipe only need to build, without increasing the fuel storage facility, prior to feeding the fuel combustion process and without preparation device, the system is greatly simplified.
For atmospheric environmental quality issues, Harbin City, Heilongjiang Province, submitted a gratifying annual summary to the people within the city. By 2018, the number of days Hashi ambient air quality standard of 310 days, an increase of 40 days, since the implementation of our 2013 new environmental quality standards, the best of the year.
January 2019, the development of ambient air quality continues to improve. "Good weather" gratifying is the result of Harbin in straw Jinshao, such as firecrackers ban on burning the same time force. Among them, strongly promote the elimination of coal-fired boilers is a top priority. According to statistics, in 2018, out of a total of 1191 Harbin coal-fired boilers to provide strong support to reduce emissions of air pollutants.
Harbin coal-fired boiler was closed down following a major way, into the central heating (including wholesale) or clean heating pipe network replacement. According to the principle "and the appropriate and, should the electric power, the gas should be gas", the clean coal central heating pipe network coverage area, the boiler unit according to claim ownership, the priority region incorporated central heating pipe network; in concentration not covered by district heating network, in accordance with the wishes of the boiler unit property, taking clean renewable energy or alternative heating means, out of coal-fired boilers.
At the same time, various related businesses also improved stations, actively cooperate with the phase-out of coal-fired boilers.
2018 Hashi out of coal-fired boilers intensity of the strongest of the year, out of range built-up area expanded from 9 to zone outside built-up areas, out of a total of 1191 units. In District 9 built-up areas, on the basis of 10 tons of steam per hour out of coal-fired boilers to achieve "clear" on the further elimination of more than 10 tons of steam per hour to 99 coal-fired boilers; county (city) district built out of steam per hour 10 116 tons of coal-fired boiler units; elimination of financial support and utilities per hour 10 tons of steam coal-fired boilers 966 units in urban and outside built-up areas in the 9th district. "Achievements accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants." Director of Air and Noise Pollution Control at the Harbin environment bureau, Li Bin Tang said.
"In order to further solve the pollution problems of coal-fired, 2019, Harbin plans in urban areas, the county (city) built-up area basically eliminated 10 tons of steam coal-fired boilers and furnaces and tea, operating the stove, coal grain storage and drying equipment coal-fired facilities; urban built-up area basically eliminated 20 tons of steam coal-fired boilers, push 35 tons of steam coal-fired heating boilers out of the urban built-up area can not be a stable discharge standards; outside built-up areas out of 10 tons of steam can not be stable discharge standards of the following coal-fired boilers. "Li Bin Tang said.
How gas boiler company list in all over india automatic control of temperature: the traditional coal-fired boilers, the boiler worker is a job must be equipped, they must not only ensure the safe operation of coal-fired boilers, we have to maintain the operation of the boiler. However, new gas boiler has passed the automated control system, all-weather running unattended, then how to achieve it? In boilers with automatic control systems, built-in temperature sensors, which during operation is equivalent to our eyes, it is responsible for the case where the operation of the boiler on the boiler to the controller by way of data. For example, a boiler with a set temperature of 55 ℃, a temperature sensor in the boiler furnace temperature acquired at this time is 40 ℃ boiler runtime. After sending the temperature data to the controller determines the control temperature is far from the set temperature, so the controlled state of the burner fire continues to heat the water in the boiler.
