一、购置热效率在60%以上的快装锅炉,更新热效率低而又使用20-30年的“煤老虎”。二、改分散供热为集中供热,热效率比现有采暖锅炉提高近一倍。三、推广烧低热值燃料(泥煤、石煤、煤矸石、油页岩等)的锅炉,节省优质燃料。四、产煤区尽量利用低质煤,把优质煤调外地,节省能源。 First, purchase quick-fired boilers with a thermal efficiency of over 60%, and update the “coal tigers” with low thermal efficiency and use 20-30 years. Second, change the decentralized heating to central heating, and the thermal efficiency is nearly doubled than that of existing heating boilers. 3. Promote the use of boilers that burn low calorific value fuel (peat, stone coal, coal gangue, oil shale, etc.) to save quality fuel. Fourth, coal-producing areas to make use of low-quality coal, the transfer of high-quality coal, save energy.
