From the 19th century is subject to the technical bottleneck of external-combustion engine technology in Shanghai and get a breakthrough, the United States alone can change the current model developing small and medium business pattern. According to 711 revealed that the self-developed 50 kW-class "external combustion" engine-related projects recently approved by experts, will be applied for in the field of combined heat and power, so that clean energy development in NGN.
To overcome two major weaknesses internal combustion engine
Although the internal combustion engine is still the world's largest energy output form, but they are "dynamic" coal fuel consumption, smoke spit fog, the mankind is facing the dual pressures of resources and the environment. Outboard engines, these two make up the internal combustion engine, "a fatal weakness."
External-combustion engine by "external combustion driven", the internal combustion of fuel into the engine is no longer widely used for biomass energy, solar energy, hydrogen energy, nuclear energy and other external heat sources, including landfill gas, biogas, including, in line with our abundant renewable energy features. National "Eleventh Five-Year Plan", only the biomass power generation capacity reached 5.5 million kilowatts, will reach 20 million kilowatts by 2020, almost the equivalent of two power-generating capacity in Shanghai, external-combustion engine will come in handy. Meanwhile, the internal combustion engine combustion forms and intermittent explosive characteristics, emit more pollutants, the outer gas turbine external heat source is a continuous steady heat, which completely burned without adequate treatment can be for Euro 5 emissions standards, much higher than current national standards.
Break the "two-century technology bottleneck"
This energy-saving and environmentally friendly outboard engines, also known as hot air machine. It must be closed in the capacity of the gas cylinder, gas in the Stirling "hot chamber" and "cold cavity" between the continued and continuous cooling heat, the temperature periodically under thermal expansion, expand and contract, thereby driving the piston and connecting rod movement, the cycle in output power. In fact, the prototype back in 1816 on the Scottish Baptist pastor Lin Faming, but has so far only the United States developed 50 kW-class commercial gas heat machine.
Going on for nearly two centuries of technical difficulties, the card is used in a closed gas cylinder outboard engines, the materials, it difficult to seal, so easy to wear.
With the rapid progress in materials science, the "century bottleneck" has finally been a breakthrough in China Stirling engine developers. They made an advanced innovation of "oil-free lubrication material" within the completely mechanical components to ensure the smooth cylinder movement, and excellent air tightness, pollution cylinder gas last longer. The original is an external combustion Stirling engine of the foundation for a wide range of applications.
Community application is not a dream
In addition to these advantages, the 711 subsidiary enterprises, "Qi Yao force" responsible "Gas Stirling Cogeneration System" projects also easy to recycle. The unit for cooling heat cold water, take away a lot of heat, the outer circulation of the water temperature can rise to 50 degrees Celsius, thus generating units in power generation also can supply hot water, or by recycling waste heat to heating, the energy efficiency increased from 30% to 80%.
It is reported that Shanghai's old landfill site in Hong Kong outside the burn unit had been introduced to "waste generation" Shanghai Spark farm stirling biogas demonstration project as well. The same unit into a home or community applications, R & D is more optimistic. According to reports, gas heat unit based modular design, according to the number of detachable power consumption can be combined, single 50 kW module "weight" of about 2,000 kg, a forklift can move it, settle down; Unit minimal vibration at work , 1 coins in the machine body can not maintain a straight back, engine noise only group with power 60% to 70%. In addition, the number of its parts smaller than the internal combustion engine four percent, using thousands of hours, only to replace the wearing parts, maintenance costs I am a professional writer from China Textile and Leather, which contains a great deal of information about silver ring designs , antique filigree jewelry, welcome to visit!
