加热设备的应用及发展

Application and Development of Heating Equipments

论述了热水加热方式，以一次换热为主的原则，但不应排除间接加热方式的存在和发展，阐述了间接加热的理论基础应为紊流加热，及由此研制的一系列新型加热设备。并介绍了近年来获得广泛运用的半即热式加热器和半容积式加热器。

Principally, Direct-heat-exchange is the main way of water- heating .But it should not exclude the existence and development of the way of Indirect-heat-exchange. Indirect-heat-exchange is based on the theory of the turbulent flow-heating.According to the theory, a series of new heating equipments were made. Two of them are discussed in this thesis. Also it introduces two kinds of heater which have found wide application recently:hemi-fast open water heater and the semi-volume heater.
