Problems solved by technology

[0002] With the rapid development of urban construction, more and more steam extraction heating units are used. At present, most units are not heat supply units when they are designed and manufactured. Therefore, most of their heating parameters do not match those of industrial users. There is a differential energy loss in the process
[0003] The industrial extraction required by the existing process heat users is generally slightly superheated steam with a certain pressure. In order to meet the requirements of the heat users, the power plant generally selects an extraction steam with a slightly higher pressure from the steam turbine. These extraction steams are generally superheated steam. Steam, whose pressure can meet the industrial requirements, but the temperature is much higher than the thermal user requirements, that is, the superheated steam will increase the superheated heat, and the power plant will cause unnecessary losses.
