1.苏联火电厂的燃料结构情况:用天然气代替重油;天然气比重目前占36.5％,并将进一步增长。新建火电机组中,天然气将用于城市附近的热电厂,火电主要依靠核能和煤炭。由于矿井加深、煤层变薄、煤质劣化,发热量由26.0降到18.9,甚至16.7兆焦/公斤。同时灰分增大,如麦基巴斯图斯煤的灰分达50％以上,所以不得不用重油稳燃。 2.针对煤质劣化情况,煤炭部门应当进行洗选,好煤送电厂,洗选下来的尾矿在当地用沸腾炉燃烧发电。必须在短时间内设计和推广沸腾炉。 3.目前,限制燃烧设备类型和参数选择、燃烧方式新探索的因素不是燃料的有机部
1. The fuel structure of the Soviet coal-fired power plant: natural gas instead of heavy oil; the proportion of natural gas currently accounts for 36.5% and will further increase. In the new thermal power plant, natural gas will be used in thermal power plants near the city. Thermal power mainly relies on nuclear energy and coal. Due to the deepening of the mine, the coal seam became thinner and the coal quality was deteriorated. The heat output dropped from 26.0 to 18.9 and even 16.7 MJ / kg. At the same time as ash increases, such as Macchiatus coal ash content of more than 50%, so had to use heavy oil stable combustion. 2. For the deterioration of coal quality, the coal sector should be washed, good coal to the power plant, washed tailings in the local use of boiling furnace combustion power generation. Must be in a short time to design and promotion of boiling furnace. 3. At present, the factors that limit the types and parameters of combustion equipment to be explored are not the organic part of the fuel
