Bioenergy, as well as solar energy, wind energy and geothermal energy are internationally recognized new types of energy. Bioenergy includes crop residue, wood chip, tree branches, industrial organic waste, etc. Compared with traditional fossil energy (coal, petroleum, natural gas, etc.), bioenergy maintains apparent advantages, i.e., clean, cheap, and renewable. China holds rich bioenergy, and Laowan Company makes full use of bioenergy, and processes it into pellets fuel (Φ18mm, length 5-9mm). These pellets bundle with Laowan patent burning equipment together, take the lead in Chinese household heating market .

　　Laowan Company’s bioenergy equipment is ideal for centralized heating in the urban and suburb areas, and particularly suitable for villas, houses and bungalows that need independent heating as well as new villages under construction. This product is characterized by economical, energy saving, and environmental protection. According to the test by the Thermal Energy Research Department of Tsinghua University, Laowan pellets boiler provides the thermal efficiency of over 80%, and emission mass concentration of less than 20mg/m3. Its CO2 emission is just 1/20 of that of coal, and 1/30 of that of oil. The emission indices fulfill type I requirements of Beijing Area, and meet the requirements on environmental protection of Chinese cities.

　　Laowan Company’s pellets boiler features very simple operation: automatic ignition; automatic feed and combustion, and feeding once a day only; automatic discharge of ash. The control system provides four combustion states, namely: big, moderate, small, and low temperature. The principal part of the boiler provides temperature display, and the flame can be adjusted as necessary. The boiler can burn the pellets which made of nearly any kinds of crop straws, and this fulfill the environmental protection requirements of all areas. The security part of the boiler is equipped with digital temperature indicator and pressure release device. There have not gas poisoning during burning, and the boiler runs at normal pressure, which is very safe and reliable.

　　Laowan Company also deliver the pellets fuel to customers in China. For use Laowan pellets fuel, it costs around RMB30 per square meter during one heating season, which is less than half of the cost of diesel oil and nature gas.
