Thermal efficiency why can tower above 20 ％
The business is energy-saving and prominent, besides using an advanced technique, the producer type that pyroelectricity couplet produces is crucial.
Common power plant generates electricity more than heat can be wasted only. If can be in more than heat,winter uses heating, use in summer for cold, burn same coal, efficiency can rise greatly.
China can Beijing heat and power plant is located in Beijing east inn of outskirt tall tablet, installed capacity 845 thousand kilowatt, load Beijing the power supply of 10% , air feed of 70% and the concentration of 30% heat addition task.

The reporter understands in interview, this enterprise is the pyroelectricity couplet with the largest size of countrywide heat addition produces a business, efficiency of aircrew annual smooth soaking is in 60% above, than tower above of groovy ammunition power plant 20 percent. And in heating period, aircrew thermal efficiency is to be as high as 84% more.
The boiler of this power plant used the advanced technique such as resume combustion of combustion of liquid state cuttings pick-up, low nitrogen, flying ash, boiler efficiency is adjacent 94% . With convention aircrew of 300 thousand kilowatt is compared, only boiler efficiency is this one tall, by year generate electricity computation of 5 billion kilowatt hour, china can Beijing pyroelectricity is annual coal of OK and managing standard 420 thousand tons. From 1999 since put into production, power plant already accumulative total is managing standard coal many tons 400.
Factory director Cai Hongwang tells a reporter: “ business is energy-saving and prominent, besides using an advanced technique, the producer type that pyroelectricity couplet produces is crucial. And if the base is produced in pyroelectricity couplet,go up, next plus ‘ cold ’ , turn a winter into heat addition, summer is offerred cold, implementation pyroelectricity Leng Lian is produced, thermal efficiency still can rise at least 10% . This summer, with generate electricity more than hot refrigeration will be in an enterprise above all in-house and pilot, to moment, the air conditioning that uses phone will be eliminated in the round inside the enterprise. ”
According to China can engineer Ceng Deyong introduces the environmental protection major of the group, pyroelectricity (cold) couplet produces efficiency tall truth is very simple, common power plant, generate electricity more than heat can be wasted only. And if can be in more than heat,winter uses heating even summer is used for cold, burn same coal, efficiency rises greatly of course. Because this country also encourages pyroelectricity all the time (cold) couplet is produced. But pyroelectricity (cold) couplet is produced also have premise, that must rely on a city namely. Because heat includes cold be different from report, cannot realize Sunday run to carry, so if the user that did not reach certain scale, heat and cold the ground that does not have use force.
