Low vacuum operation in thermoelectricity plant for direct heating offers good benefit, however, operating stability will be influenced with the increasing in heating load of network, therefore concept of conversion of direct heating into indirect heating was put forward.
因此提出适时向间接供热的转换问题。
Surveys the current practical operation conditions of the boilers of the primary circuits in nine typical indirect heating systems in Beijing.
