一、蒸气蓄热器的原理及构造 (一)变压式蒸气蓄热器的原理变压式蓄热器,实为热量存储器。作为蓄热的载体,使用的是比热较大的饱和热水。因为同一容器,使用饱和水比不用饱和热水,其全蓄热量可达原蒸气蓄热的70倍左右。向压力容器内的水通人剩余蒸气时,容器内的水温逐渐上升,随之容器内压力也将升高。这样,余热就变成高温高压的饱和热水被储存起来。容器上设置出口,根据需要,在自动减压的同时,产生一定蒸气。随压力升高而蓄热,随减压而放出蒸气,所以叫变压式。具有代表性的构造如图1。
First, the principle and structure of the vapor heat accumulator (A) The principle of variable pressure vapor heat accumulator Transformer type heat accumulator, in fact, thermal memory. As a heat storage carrier, saturated hot water having a larger specific heat is used. Because the same container uses saturated water rather than saturated hot water, its total heat storage capacity can reach about 70 times that of the original steam heat storage. When water is left in the pressure vessel, the temperature of the water in the vessel gradually rises, and the pressure in the vessel increases. In this way, the saturated hot water whose residual heat becomes high temperature and high pressure is stored. The outlet is set on the container, and a certain amount of steam is generated at the same time as automatic decompression as required. As the pressure rises, it accumulates heat and releases steam with reduced pressure. The representative structure is shown in Figure 1.
