In a city in a very cold region where central heating is provided by thermal power plants, these plants use back-pressure heating steam turbines. Which of the following statements is incorrect? ( ) (A) This heating method has the highest thermal efficiency. (B) This heating method can handle the heating load throughout the entire year. (C) This heating method requires the use of regional boiler rooms for adjusting heating output as needed. (D) This heating method can only meet the basic heating demand during the heating season. A new activity has started in the production area; the prizes are attractive, so hurry and participate: 【Production in Summer】 – The production area has entered the “training during the hot summer days” mode
It can be seen that the back-pressure type has the highest thermal energy utilization efficiency. However, due to the mutual constraints between thermal and electrical loads, it is only suitable for providing the heat required to meet the basic thermal load throughout the year or during the heating season. It is necessary to set up a district boiler room for peak-shaving heating. Therefore, choose answer B
B is wrong-------------
(B) This heating method can handle the annual heating load
