Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1,
The utility model is achieved through the following technical solutions：A kind of shell-and-plate steam generator, including autoclave housing
With the plate beam 9 being fixed in autoclave housing 8, one end of autoclave housing is provided with heat source medium entrance 5 and thermal source with plate Shu Liantong
Media outlet 6, autoclave lower housing portion and top open up cold water inlet 10 and steam (vapor) outlet 3 respectively.Housing is using autoclave structure
In order to increase the vapor phase space of steam spilling.Shell-and-plate steam generator heat source medium typically uses the hot water of factory 150 or so
Or 200 degree or so conduction oils, into inside the plate beam of steam generator, the water heating of plate beam side is produced steam.Thermal source
