In order to broaden the market application of power plant energy saving and consumption reduction, and meet the needs of users for waste heat utilization, HASTEAM has developed a highly adaptable low carbon energy saving device based on the new heat net condenser, which has been widely recognized by users.

The technical principle of the product is as follows: in the heating period, the return water of the heat network is fed into the condenser, the steam engine runs under high back pressure, and the return water of the heat network is heated to the expected temperature by the lack of steam, so as to achieve the purpose of waste heat utilization. The economic benefits are considerable, and it can meet the diversified needs of different power plants.

The low carbon energy saving device based on the new heat network condenser has the advantages of high waste heat utilization efficiency and strong flexibility. The main technical and economic indicators are as follows: the energy utilization rate of the power station is increased from about 40% to nearly 100% at the time of pure condensation; The coal consumption of power generation unit is greatly reduced. Increase the heating capacity of the unit in winter by 20-120%. The innovation is: breaking through the small-end difference of HEI standard; The special water chamber structure is suitable for the high temperature difference and high pressure of the heat network backwater. Research and application of special structure suitable for low water circulation rate and high temperature rise of heat network; Condenser with large opening lack steam extraction structure.

The application of the low-carbon energy saving device based on the new heat network condenser in the collaborative thermoelectric decoupling double cold source low vacuum heating system is the first heating system applied in the fields of energy saving, cogeneration and waste heat in China, which is of great significance in the field of power station energy saving and flexible operation. Low-carbon energy-saving devices based on the new heat network condenser have unique advantages in the cascade utilization of energy in power plants, reducing the coal consumption of units and improving the flexibility of units. It is estimated that there is a huge demand for energy-saving transformation and performance improvement of thermal power units in service.
