在火力发电厂中,锅炉房的除灰渣作业,历来是体力劳动强度极大、劳动条件极差的一个工序,长期从事这一作业的工人往往染有矽肺等职业病。解放后,由于党和国家对劳动人民健康的关怀,很多电厂已经安装或改善密闭的水力排灰渣设备,大大改善了劳动条件。但由于水力排灰渣设备投资昂贵,灰渣堆贮场地占用大片可耕农田以及湿灰渣难于综合利用等原因,我国各地的电力工业正在努力寻求机械化干式密闭除灰渣的途径。特别对于水源
In the thermal power plant, the operation of removing ash in the boiler room has always been a process with great manual labor force and poor working conditions. Workers who have been engaged in this operation for a long time often have occupational diseases such as silicosis. After the liberation, due to the party and state’s concern for the health of working people, many power plants have installed or improved confined hydraulic ash discharge equipment and greatly improved working conditions. However, due to the high cost of hydropower ash and slag equipment, the large area of ash farm and the difficulty of comprehensive utilization of wet and hard ash, the power industry in various parts of China is striving to find a way of mechanized dry and closed ash removal. Especially for water
