Natural Gas fired Steam Boiler for Industrial Heating
Hot water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
Electric fired steam boiler for industrial heating combustion efficiency and how to save more: In China container industry is a growing industry, and container industries and enterprises are also faced with various challenges. Container industry must adhere to market-oriented strategy, closely rely on scientific and technological progress, scientific and technological innovation, under the guidance of national energy and environmental policy, company structure and product structure adjustment, manufacture and sale of container in line with market demand, occupancy in the fierce competition in the market place. Electric steam boiler to improve the combustion efficiency, saving fuel, the fuel quality should be controlled, uniform atomization burner. To achieve the above object, the following points should be noted: 1 to understand the combustion principle, adjusting the wind ratio of positive oil (gas), to achieve efficient combustion; 2, to maintain a good working condition of the nozzle, the nozzle is not easy too large or too small, the nozzle wear obstruction, carbon status, to ensure good atomization combustion conditions. 3, to maintain proper pressure or hydraulic, pneumatic or steam boilers, such as high or low oil pressure, and a hydraulic or pneumatic pressure is too large or too small, will affect the mixing of fuel and air uniformly. 4, to adjust the burner flame length brains spray angle size and shape of the combustion chamber with fire furnace chamber filled eye, achieve economic combustion. No black smoke, no soot, in the good sense of the coming year running.
If you know a little about chemistry, you may know that the sulfur content of oil and coal is roughly equal, but ask what low-temperature corrosion of oil-fired boilers is much more serious than coal-fired boilers, for two main reasons:
1. 90% of ash in coal-fired boiler, especially coal powder furnace, is taken away by flue gas, sulphuric acid steam formed in flue gas is absorbed by fly ash in flue gas, so that sulfuric acid vapor in flue gas is reduced, and about half of sulfur remains in ash when coal is burned. When the oil is burning, the sulfur content in the fuel almost all changes to the ash in the SO2, fuel, the fly ash in the flue gas is very little, and the adsorption ability to the sulphuric acid vapor in the flue gas is very weak.
2. The hydrogen content of oil in the oil-fired boiler is about 11%-12%. The combustion of each ton of fuel oil can produce about 1 ton of water vapor, and the partial pressure of steam in the flue gas is higher than that in the case of coal-burning.
Factors industrial boiler energy-intensive factors which have high energy consumption of industrial boilers which 1, energy consumption is low management level industrial boiler is too large, there are currently a lot of long-term business. On the one hand understanding of the enterprise energy conservation boiler is still not sufficient, on the other hand the energy management level is still at a low level, and even some companies even the most basic measuring instruments are not equipped. In order to reduce operating costs, many companies have to buy the old boiler use, lack of components purchased fuel means of inspection. Even in the case of raw coal screening is not performed, it is directly put into production use, it is difficult to ensure full combustion of coal. Not only the thermal efficiency is low, but also resulted in a waste of fuel. 2, heat recovery is poor combustion is incomplete, the situation is the high rate of heat loss is extremely common in industrial boilers used in the process, saving the main parameters of the boiler will be exceeded. Economizer function is to heat energy recovered, but in actual use, heat recovery efficiency is very low. In this case, do not use a lot of boiler economizer direct altogether, inevitably produce exhaust gas temperature is too high. Meanwhile, return the device and steam condensate recovery, it has not been fully appreciated and better use, some are put to use in the boiler after installation, and did not take appropriate measures to deal with poor recycling effect. 3, lack of effective supervision of the level of energy service work, depends largely on the level of experience and technical personnel. But in practical terms, due to the lack of technical personnel, resulting in the energy service work at the level of the low. Various enterprises produced energy-saving products with high imitation, coupled with the lack of effective supervision of energy-saving measures, resulting in the entire market of energy-saving products more confusing. The effect of not only energy-saving effect is not ideal, and to transform the poor, the performance of energy-saving products remains to be greatly improved. Market confusion, vicious competition phenomenon has not been fundamentally curbed.
