当前,由于住房条件的限制,我国城镇、乡村有相当一部分家庭还用煤炉做饭,冬天靠煤炉取暖,洗澡难的问题还没有解决。另一方面,煤在普通煤炉里热能利用率很小,很大部分从烟筒里冒出去,既造成了极大的浪费,又污染了环境。随着人民生活水平的提高,煤炉的发展趋势一是多功能,二是节能。从1985年～1988年,仅家用多功能节能煤炉的专利申请就有300余件,其中有适合无集中供热的楼房、平房之用的做饭、取暖、 At present, due to the restrictions on housing conditions, a considerable number of families in our towns and villages still use coal stoves for cooking. In winter, heating by coal stoves is difficult. The problem of difficult bathing has not yet been solved. On the other hand, the utilization of coal in ordinary coal stoves is very low, and most of the heat is emitted from the chimneys, causing great waste and polluting the environment. With the improvement of people’s living standards, the development trend of coal stoves is firstly multi-functional, and second, energy conservation. From 1985 to 1988, there were more than 300 patent applications for domestic multi-purpose energy-saving coal stoves, including those suitable for buildings without central heating, cooking and heating for cottages.
