Problems solved by technology
my country has done a lot of research work on micro gas turbines, but there is still a huge gap compared with foreign countries, and some researches are still incomplete. Among them, the utilization rate of high-temperature flue gas output by micro gas turbine turbines is relatively low, and its use is relatively extensive. During the use of micro gas turbines, the utilization rate of the high-temperature flue gas output by the turbine is low, and the heat loss is relatively large. Changes will lead to unstable heating and affect the heating effect
Therefore, when using micro gas turbines for heating, there are disadvantages of poor temperature control effect and low heating stability.
