Steam generator or the heat exchanger being arranged in last N steam generator are provided with steam (vapor) outlet, each steam generator
Interior heat exchanger is all sequentially connected in series and is being provided between the heat exchanger of cooling water inlet and the heat exchanger being provided with steam (vapor) outlet, therefore
Steam generation module unit of the present invention, steam generation faster, steam production enough, vapor (steam) temperature can reach 165 degree and steam
Humidity is low, and the therefore present invention more can meet that hotel, restaurant, dining room, hotel, enterprise etc. be fast to the generation of steam, high-temperature, high yield
Amount, low-moisture high request.
(2)In addition, the temperature difference between the indoor heat exchanger of burning is big, two heat exchangers are also susceptible to heat exchange, from
And be conducive to the low heat exchanger of temperature fully to recycle the indoor gas thermal energy of burning so that the low heat exchanger of temperature exists
Burning interior is preheated effectively, and this takes full advantage of gas thermal energy, improves the utilization rate of gas thermal energy, so that this
Invention more energy-conservation, and, when heat exchanger is heated, the low heat exchanger of each burning indoor temperature all obtains effectively pre-
Heat, pre-heat effect is good, thus improve vapor (steam) temperature and the steam production rate of the present invention.
(3)More have plenty of, because the indoor most of gas thermal energy of burning is absorbed by the heat exchanger of steam generator, from
And reduce operating pressure and the operating temperature of smoke exhaust fan, extend the service life of smoke exhaust fan.
(4)The nozzle of the present invention is necking valve, and in throat structure, according to fluid mechanics principle, this kind of structure makes nozzle
The pressure of inlet side is more than the pressure of outlet side, and this is effectively prevented steam in heat exchanger due to unstable and flow back or go here and there
Stream, makes the steam in first heat exchanger can only be toward the steam outbound course stream of first heat exchanger, it is to avoid opposing steam flow and lead
Cause whole system unstable.
