Device, because blocked drain easily causes stream-liquid two-phase flow, a series of problem such as hydrophobic problem of initiation.
2nd, it is to realize that hot water steam air heater adapts to the adjustable function of variation of ambient temperature, the hot water before hot water steam air heater entrance
Pipeline is provided with electric gate valve and electric control valve, by adjusting the flow of hot water, to adjust the temperature of hot water steam air heater outlet.
3rd, by setting hot water pipeline to bypass, the normal water supply of boiler is can ensure that, while full in summer or environment wind-warm syndrome
Under the operating mode of sufficient condition, hot water passes through from 100% bypass, without hot water steam air heater, so as to realize that 100% does not heat air feed
Switching.
4th, by being provided with check-valves in the hot water steam air heater port of export and before bypass interface, prevent by hot water pipeline
When road is opened in hot water adverse current to hot water steam air heater body, on the heat pipe before non-return valve, electric gate valve and drainpipe are set,
Facilitate discharging water and overhauling for system.
Brief description of the drawings
Fig. 1 is a kind of hot water steam air heater system schematic by the use of high-pressure feed water as thermal source of the invention.
Embodiment
