System Energy conservation Technology of High Temperature Condensate Closed Loop Recovery and Steam Heating Network
The demand for energy conservation and emission reduction has become a consensus of the international community. Achieving energy conservation, efficiency improvement and emission reduction at the same time has become an urgent requirement of system operation and production safety. More and more attention has been paid to energy conservation and emissions reduction in plant operations, and special efforts have been made to research, develop and apply advanced energy conservation and emission reduction technologies.
High temperature condensate recovery closed-loop and steam heating network is an energy-saving technology applied in heating production. It takes condensate from the energy-saving turbine of the end of the process to carry out the condensate recovery and closed-loop circulation, and then to supply steam. The closed-loop condensate can be recycled by the auxiliary condensing unit of the closed-loop system. In the production process of steam heating, the thermal energy can be fully recovered, which can not only greatly improve the utilization rate of energy, but also reduce the energy loss.
The high-temperature condensate recovery closed-loop and steam heating network system energy-saving technology is mainly used to reduce the energy consumption of the production process, improve the overall energy utilization rate and control the steam pressure in the steam network. As high temperature condensate recovery system mainly depends on circulating water to complete the recovery of condensate enthalpy, the circulating water should have required temperature and enthalpy. In order to reduce the energy loss of recovery system, reasonable control of system operation and maintenance measures can guarantee the reasonable operation of the system.
The high-temperature condensate recovery closed-loop and steam heating network system energy-saving technology has the following advantages. On the one hand, the system has a high recycling rate, which is beneficial to improve the utilization rate of energy. On the other hand, the system has high stability, which can make system pressure stable and improve the safety of process production. In addition, the smoke and dust emission standards of steam boilers are higher than those of thermal power plant boilers. Finally, the operation pressure of the steam heating network can be reasonably controlled, which is conducive to the improvement of the thermal efficiency of the steam boiler system.
The high-temperature condensate recovery closed-loop and steam heating network system energy-saving technology is suitable for the production environment of heating and steam supply. In order to improve its energy-saving effect, reasonable system design and operation could be adopted to carry out reasonable energy-saving practices. Firstly, the reasonable design of heat load and condensate closed-loop should be considered in the design process. Secondly, auxiliary condensing device should be used in the system and reasonable operation should be ensured. Thirdly, reasonable selection of pumps and pump control valves should be taken into consideration. Finally, it is necessary to carry out regular inspections and maintenance of the recycling closed-loop to ensure the stability and safety of the system.
In conclusion, high-temperature condensate recovery closed-loop and steam heating network provide an efficient and reliable system energy-savings technology for plant processes. It can not only reduce energy consumption and improve energy utilization rate, but also ensure the safe operation of process production. Therefore, it is necessary to pay attention to and improve the sustainable development level of high-temperature condensate recovery closed-loop and steam heating network system.
