On May 12-13 this year, the South African International Energy Week exhibition of a new energy once again raised concern, as the African country and the first power of the most economically developed countries, the more developed South Africa's power industry, power generation accounts for the whole of Africa 60% of South Africa's electricity Union or the Member States (SAPP) and Africa's leading exporter of electricity, supply of electricity to Botswana, Mozambique, Namibia, Swaziland, Zimbabwe and other neighboring countries. However, with China in recent years to accelerate the development of industrialization, increasing demand for electricity in South Africa, with a total demand of about 34,000 MW, while the national generating capacity is about 29,000 megawatts, and the gap of about 05 000 MW. To this end the Government of South Africa in April 2011 specifically set aside $ 10 billion to the South African power company ESKOM for the development of power industry.
In this case we can consider the next person deal with the problem of coal combustion that, in addition to the comprehensive utilization of fly ash produced by thermal power plants and development of new building materials - fly ash brick outside, no other use. Insiders just such two accounts: first pen, common approach to deal with heat and power plant fly ash is landfilled. Construction of a 300 m long, 400 meters wide, seven meters deep landfill pool, needs 1,200 acres of land, plus the slope, seepage, spill, landfill, rehabilitation and other expenses, a total of about 30 million yuan. In addition, the annual payment required environmental costs of landfill arable land around the pool of nearly one million. Construction of a production of 100 million ash sintered brick of the new environmentally friendly building materials companies, equipment investment needs of about 800 million yuan, annual output will reach 24 million yuan (at current market prices), annual profit of 200 million yuan (after deducting actual cost, irrespective of management efficiency factor). The second tranche: 100 million fly ash brick masonry 250,000 square meters of buildings can be. Compared with an ordinary clay brick, saving nearly 200 acres of land resources (with less than 100 cm of surface soil grown plants have the ability to calculate the standard).
Fly ash brick produced by the thermal power plants of industrial waste - fly ash and ordinary slag, shale as the main raw material, through mixing, extrusion, molding, firing. This new building materials products, raw materials for more than 80% for industrial and domestic wastes, is determined as environmental protection, energy saving products. The use of fly ash brick made building materials, the total project cost can be reduced 6-8%, with a significant social and economic benefits.
This approach not only solve the problem of industrial waste, but also reduces environmental pollution but also for enterprises to bring additional value-added point of interest, but also alleviate the problem of employment is now in some countries.
