随着国民经济的不断发展,对节能技术的开发愈益迫切。区域性集中供热是一种很有效的节能方式,而背压式汽轮机由于结构简单,供热量大、容易投建上马而得到广泛的应用,容量也日益增加(已达20～30万kw)。但是,背压式汽轮机的电负荷受到热负荷的牵制(称强制性调节)当负荷经常变动时会使机组的运行能力得不到充分的发挥。本文探讨一种方法,即在利用背压机组作热源的供热系统中加装一蓄热器,便可使背压汽轮机能在一定范围内实现热电负荷的非强制调节,这对保持背压机组高的运行经济性十分有利。文中以一供
With the continuous development of the national economy, the development of energy-saving technologies is increasingly urgent. Regional centralized heating is a very effective energy-saving method. Back-pressure turbines are widely used due to their simple structure, large heat supply, easy installation, and increased capacity (up to 200,000 to 300,000 kw). ). However, the electric load of a back-pressure turbine is hampered by the heat load (referred to as “mandatory adjustment”). When the load is frequently changed, the operating ability of the unit cannot be fully exerted. This article discusses a method of adding a heat accumulator in a heating system that uses a back pressure unit as the heat source to allow the non-mandatory adjustment of the thermoelectric load within a certain range of back pressure turbine functions. This maintains the back The high operating economy of the press unit is very advantageous. One for the text
