一、供热汽轮机的负荷供热汽轮机的负荷有热和电两种。对于背压式汽轮机(包括带有调节抽汽的背压式汽轮机),它的电负荷依赖于热负荷的变化而变化。带有调节抽汽的冷凝式汽轮机,它的电负荷和热负荷是各自独立的变量,任一负荷的变动都会引起流量的变动,从而使其处于部分负荷下运行。热负荷,一类是0.8—2.5ata的采暖用汽,这一类用户包括我国东北、华北和西北三个地区。由于初冬到一月份温差较大,其变动量也较大,例如东北地区,从0℃到零下30—35℃,华北地区最冷到零下20℃,西北的兰州和乌鲁木齐与华北和东北地区
First, the load on the steam turbine Steam turbine load on the heat and electricity are two. For backpressure turbines, including those with turboexhaust, the electrical load varies depending on the thermal load. Condensing steam turbines with regulated extraction, whose electrical and thermal loads are independent variables and any change in load causes a change in flow to operate at part load. Heat load, a class is 0.8-2.5ata heating steam, this type of users, including China's northeast, north and northwest three regions. Due to the large temperature difference between the early winter and January, the variation is also large. For example, in Northeast China, from 0 ° C to minus 30-35 ° C, the coldest in North China to minus 20 ° C, Lanzhou and Urumqi in the northwest and North China and Northeast China
