Problems solved by technology

When the output load of the system decreases, the gas turbine operates at reduced load, and the efficiency decreases, which in turn affects the waste heat utilization equipment in the system, and the system performance will also decrease
At present, there is no effective solution to this problem, which not only affects the energy-saving characteristics of the distributed cooling, heating and power system, but also hinders the popularization and application of distributed cooling, heating and power technology.
