particularly, described Heater group comprises two above ptc heaters.
more specifically, described two above ptc heaters are in series, or two in described two above ptc heaters are in parallel, are in series between remaining ptc heater.
again particularly, described Heater group is comprised of the first ptc heater, the second ptc heater and the 3rd ptc heater, wherein the first ptc heater and the second ptc heater are in parallel, and their water inlet is communicated with described water inlet pipe, the water inlet of described the 3rd ptc heater is communicated with the steam (vapor) outlet of the first ptc heater and the second ptc heater.
particularly, the described water unit that supplies also comprises the Calibration Column for the described measuring pump of verification, and described Calibration Column is connected with the water inlet pipe of the import department of close described measuring pump by demarcating arm, on described demarcation arm, is provided with hand-operated valve.
particularly, described for water unit also comprise the buffer of the flow for stablizing described water inlet pipe, for the counterbalance valve of the pressure of stablizing described water inlet pipe, described buffer and described counterbalance valve are separately positioned on the water inlet pipe between described measuring pump and described a plurality of Heater group.
particularly, the described water unit that supplies also comprises that the people that supplies on the water inlet pipe be arranged between described measuring pump and described a plurality of Heater group observes the flowmeter of the flow of described water inlet pipe.
particularly, described steam raising plant also comprises the steam outlet pipe be connected with described steam (vapor) outlet, the demister that is arranged on the globule of not vaporizing fully for filtration on described steam outlet pipe.
more specifically, described steam raising plant also comprises that the confession people who is arranged between described water inlet pipe and described steam outlet pipe observes the quartzy liquid level gauge of liquid level, is arranged on Pressure gauge and thermometer on described steam outlet pipe.
beneficial effect of the present invention is:
the present invention by arranging measuring pump on water inlet pipe, and adopt a plurality of ptc heaters to be heated, measuring pump can accurately be controlled the influx of water, and ptc heater can dry combustion method, therefore the water flowed into wherein can be changed into to water vapour fully, thereby can accurately control the quantity of steam of generation, can be used for needs and accurately control in the reaction of steam addition.
