7.More than heat generates electricity is to accord with a country to reach the policy policy that can develop continuously about environment of resource conservation, protection. National regulation, the more than pyroelectricity that is more than 1000 kilowatt to the capacity stands, should termless get online and give favourable online electrovalency.
Of the high speed development as economy, resource decrease, the farther aggravate that the market competes and low temperature more than heat generates electricity of the technology increasingly mature, the pure low temperature of efficient, energy-saving, environmental protection more than heat generates electricity technical project, will more and more be taken seriously by the height of people.
Current, industry of our country cement already had partial manufacturer to use more than heat to generate electricity technology, construction resource uses a power station integratedly. But used for the most part belt fill the more than heat that lights boiler generates electricity technology, still need coal fired, the system is more complex, efficiency is low. As resource decrease stage by stage and people is energy-saving of environmental protection consciousness rise, and the country can be small to high cost the limitation of igneous report, people begins to use more than hot resource, especially the microtherm beyond hot resource of low grade also begins to be taken seriously. Cement plant introduces peaceful state of Anhui conch group pure low temperature of Japan more than heat generates electricity equipment applies at product line of 4000t/d cement grog, 1998 and the net generates electricity to succeed, systematic moving case is good.
2, pure low temperature more than heat generates electricity technical current situation
Well-known, have inside the industrial business such as cement, steely, building materials, chemical industry, pottery and porcelain many everyday 24 hours are discharged outwards under 400°C in the more than hot resource such as microtherm flue gas, useless vapour, useless hot water. The energy that they carry belongs to heat of medium, microtherm beyond. If do not try to use, many more than hot natural resources is about for nothing waste.
Current, to as above product line of more than hot resource use have two kinds of kind roughly: One kind is to use its heat energy to supply production or life need directly, its utilization rate is very low; Another kind is to use product line more than hot resource changes his into use convenient transport agile electric energy, the cement kiln that can offer an alternative more than heat generates electricity the technology has the following kinds about:
1) belt fill the more than heat that lights boiler generates electricity technology. Because was used,fill light boiler, whole system is even more complex than power plant of firepower of a diminutive, move rise to be bothered even, efficiency of diminutive firepower power plant is low, pollution is big, waste resource. Country already public proclamation does not get power plant of reconstructive diminutive firepower. Accordingly, add to use the more than heat of low grade power plant of firepower of a diminutive is unreasonable.
