Low-temperature geothermal, is 100 degrees below the ground water. People to use low temperature geothermal ground water from the beginning.
China is the first natural geothermal countries. According to historical records, BC 500 – 600 years ago before the Eastern Zhou era, people understood how to use underground hot water bath treatment and irrigation, but Read More…
Furnace, full name of the boiling fired boiler. Its biggest advantage is the low quality coal to burn low calorific value, coal, oil shale and other fuels. The calorific value of coal is about ordinary 20900-25080 kJ / kg, and these low calorific value fuel is only 4180 kJ / kg as such, it is difficult to burn in an ordinary boiler. Over the years, coal mining coal piles, “tasteless gesture.” In some areas rich in coal resources, which can not use, need Read More…
Lignite brown coal use more of a role in only a rock ? from the peat into the role of lignite) coal.
