本文根据当前我国能源供应的形势:油、电供应较紧,煤炭供应较缓,而且电、煤的热量比价悬殊。指出推行节电省油,以煤代油,以煤代电具有重要的意义。特别是对油电供应紧张,缺电而严重影响生产发展的地区,对使用燃油和电热供热设备改用燃煤供热就更为十分必要。它不但可以节电省油,缓和油、电供应的紧张情况,促进地区的生产发展,取得良好的社会效益外,而且对企业还具有良好的经济效益,是当前节能的一个重要途径,以纺织印染工业中 M751B—160型热定型机“电改煤”——由电热改为燃煤热油供热为例,论述可获如下效益:节减电功率390千瓦,年节约电能195万度电,年经济效益42万元,投资偿还年限为0.57年。显然,这一改造效益是十分可观的.
This article based on the current situation of China’s energy supply: oil, electricity supply is tight, the coal supply is slow, and electricity, coal, the great disparity of calorific value. Pointed out that the implementation of energy-saving fuel, coal instead of oil, coal on behalf of electricity is of great significance. Especially for areas with tight supply of oil and electricity and lack of electricity that seriously affect the development of production, it is even more necessary to switch to using coal-fired heating for fuel oil and electric heating equipment. It not only can save energy and fuel, ease the tension of oil and electricity supply, promote regional production and development, achieve good social benefits, but also have good economic benefits to enterprises. It is an important way to save energy at present. Textile dyeing and printing Industry M751B-160 heat setting machine “electric reform coal ” - from electric heating to coal-fired hot oil heating for example, discussed the following benefits can be obtained: 390 kilowatts of power savings, the annual saving of 1.95 million kilowatts of electricity, The annual economic benefit is 420,000 yuan, and the investment repayment period is 0.57 years. Obviously, this transformation benefit is very substantial.
