waste fuel
4.In 1995 the waste water treatment rate of the industrial enterprises above the county level all over the country reached 76.8 percent; the smoke and dust removal rate of waste gas from burning fuel, 88.2 percent; waste gas purification rate from production processes, 68.9 percent; and the comprehensive utilization rate of industrial solid waste, 43 percent. Output value attained through the comprehensive utilization of the industrial ``three wastes' came to 19 billion yuan.
5.After 30 years of efforts, North Korea has built six nuclear research centers, two research reactor, six uranium deposits, the three uranium dioxide conversion plant, a natural uranium fuel element factory, a nuclear test reactor and a nuclear waste storage site, the domestic proven recoverable uranium reserves amounted to 4 million tons, basically built from uranium mining to nuclear waste disposal of the nuclear fuel cycle system.
6.War, invasion act of foreign enemy, hostilities (whether war is declared or not), civil war, rebellion, insurrection, military force or coup, strikes, riots or caused by or arising from ionising radiation or contamination by radioactivity from any nuclear fuel or from any nuclear waste from the combustion of nuclear fuel.
7.The heat balance equations on incineration of organic liquid waste in fluidized-bed incinerator with coal as auxiliary fuel is established in this paper.The relations between the feeding rate of auxiliary fuel and the LHV of liquid waste,the incineration temperature,and the preheated combustion air temperature have been discussed.This paper also discussed the relation between the LHV of liquid waste and combustion air temperature as the auxiliary fuel is not necessary,and provides the theoretical foundation for the design and operation on fluidized-bed incinerator.
8.We are also looking at the potential for developing waste-to-energy incineration so as to reduce our reliance on fossil fuel.
9.The recent advances of sustainable petrochemical production technologies in the following fields are reviewed, including the atom economy oxidation of hydrocarbons with H2O2 as oxidant, green chemical synthesis with non-toxic and harmless raw materials, chemical reaction using environmentally friendly catalysts, chemical reaction in new green solvents, recovery of polymers waste, and production of petrochemicals and biodiesel fuel from renewable resources.
