随着能源日趋紧张,煤炭价格一涨再涨,节能煤炉的开发已成为人们非常重视的课题,这一课题是大有潜力可挖的,这是因为目前一般煤炉的热能有效利用率仅为20％,也就是说,在煤炭燃烧过程中有一半以上的热能被白白浪费。纵观当前民用煤炉的攻关方向,主要集中在保温型、助燃型及多用型 As energy becomes increasingly tense and coal prices rise and rise again, the development of energy-saving coal stoves has become a topic that people attach great importance to. This subject has great potential to be excavated. This is because the current thermal efficiency of coal stoves is only effective. It is 20%, that is, more than half of the heat energy is wasted in the process of coal combustion. Looking at the direction of the current civil coal stoves, mainly focused on thermal insulation, combustion-supporting and multi-purpose
