This technology changed the traditional combustion way and significant reduced the fuel consumption. It's fully in correspondence with energy saving and low emission, recycle and low-carbon economy concept. It's a revolutionary new energy technology because of its perfect characteristic and roles on minimizing raw materials, reusing, and recycling. It has a good market prospect in extensive industries like hazardous wastes incineration, municipal wastes incineration, thermo-electric generation, industrial heating furnace catalytic combustion, and so on.
The industrial heating furnace mainly includes industrial boiler, industrial stove, chemical heat treatment, drying processing,municipal central heating boiler, etc. The three key technologies of the industrial heating furnace are to raise the combustion level, to improve the heat exchanging rate, and to lower the system operation and maintenance costs. The Oxy-hydrogen burning technologies of the industrial heating furnace meets the three key requests.
The industrial heating furnace is an important equipment for manufacturing, but it's also a large fuel consumption equipment. Most China's industrial fuel burner (different with the industrial electric burner) stand on a low integral level so it wastes a lot of raw materials with low fuel.
utilization efficiency, and its combined efficiency of processing, transformation, transportation and terminal using is only 31%-32% which is 10% lower than the international advanced level. Therefore, the high efficient oxy-hydrogen combustion technology can satisfy the requirements to lower the industrial heating furnace fuel consumption (an improved energy saving combustion technology) at this very moment. It's not only in line with the government energy policy, but also enjoyed all the favorable conditions in the present worldwide high oil price situation.
China is the biggest coal producing country and consuming country in the world. The coal accounts 75% of the country's total energy demand. Therefore, the coal occupies an important strategy position in China's energy consumption, and a coal-dominated energy structure won't be changed in a short period. In China, the coal-electric conversion efficiency is very low (average rate of 32% in China, and 40-50% in developed countries, the coal consumption of the coal-ired generating unit is 379g/KWh
in 2004 in China, which is 60g higher than the world advanced level ), and the pollution is very high (80% of the air pollution is from fuel combustion), which led to a high production cost and a bottleneck in coal-fired power plant construction. Therefore, to enhance the coal-electric conversion rate and to save the coal resources would be the most key purpose in the future, it is an important leverage to carry out the coal-fired power plant sustainable development. The oxy-hydrogen catalytic combustion technology is not only a complement and improvement to the Clean Coal Technology (CCT), but it also fix up a new technical route. The oxy-hydrogen generator has an enormous and potential market as a auxiliary equipment in thermal power stations.
The oxy-hydrogen catalytic combustion technology used in clean coal power industry can improve the coal-fuel output coefficient and save energy and reduce operation costs.If it can be realized in the industrial application in soonest time, it will certainly relive the pressure of coal electric power plants.The experiment shows that adding appropriate oxy-hydrogen on the nozzle of the coal-fired power plant's furnace can reduce carbon oxides(NOx) emission from 300mg/m³ to 100mg/m³ or below,which brings huge environment and economic benefits.
Adding oxy-hydrogen to the fossil fuel can change the combustion status as shown in the following pictures:
In China, the cities produce average 440kg wastes per person per year, and the country's annual total output is more than 150 million tons and still with an increase rate of 8%-10% per year. Compared with the landfill and composting, the wastes incineration is more broadly used for efficient heat recovery, decontaminate, minimizing and recycling purpose.
There are some wastes incineration power plant with wastes treatment capacity of more than 1000 tons/day which have been put in schedule or already founded in some large and medium-sized city, such as Bejing, Shanghai, Guangzhou, Shenzhen, Ningbo, Hangzhou, and so on. The founding of wastes treatment and incinerator center can relieve the municipal wastes processing pressure and conserve the land, but it also has brought lots of problems.
The wastes incineration secondary pollution (especially the dioxin ) has Increasingly become a prominent problem in China and abroad. The dioxin as a first class toxicant, the 2, 3, 7, 8-TCDD in it has a toxicity of 1000 times higher than the potassium cyanide (KCN). The dioxin is called to be "the most toxic poison on the earth" In view of this, ”Stockholm Convention on Persistent Organic Pollutants" is put out to control the dioxin emission, and China as one of the signatory countries, also published "Technical requests for medical wastes incinerator " (GB19218-2003) and "household wastes control standard" (GB18485-2001). To apply the oxy-hydrogen in dangerous wastes and garbage incineration technology, will not only improve the furnaces combustion efficiency and lower the soot and CO emission, but also inhibit the dioxin generation.
Recently, some of similar products and applications appeared in domestic and international market has indicated a good market prospect and significant economic and social benefit.
