Send out section support plate, the water side body include diameter segment, gradually big section of diameter, larger-diameter section, the preheating section every
Plate is staggered in diameter segment so that water is turned back flowing between the preheating section partition plate, changeover portion separation
Partition plate is arranged on gradually big section of the diameter, and changeover portion separation partition plate top is arranged to flow-guiding structure, the evaporation
Section support plate is arranged on the larger-diameter section, and the larger-diameter section is provided with steam (vapor) outlet.
The integrated steam generator, the flow-guiding structure leave necessary distance with water side body, ensure production
Raw saturated vapor is discharged in time from changeover portion.
The integrated steam generator, in the last one preheating section partition plate to the diameter gradually big section in diameter segment
First evaporator section support plate between space be changeover portion, the space before the changeover portion is preheating section, described
Space behind changeover portion is evaporator section, and only there are one changeover portions in the changeover portion to separate partition plate.
The steam generating method of the integrated steam generator, heat medium enter heat exchanger tube by heat source import, lead to
Heat exchanger tube is crossed by after shell side feedwater heating, is discharged by thermal source outlet, is fed water and enter evaporator preheating section through feed-water inlet nozzle,
Baffling exchanges heat in preheating section, enters changeover portion after improving water temperature, is further heated in changeover portion, in heating process, given
It is heated as the part of saturated vapor in water to separate between gap is discharged into evaporator section air above partition plate by changeover portion, water then leads to
Cross lower passage and enter evaporator section and further heat generation saturated vapor, saturated vapor finally by steam (vapor) outlet device for transferring outside.
Beneficial effects of the present invention：
The present invention cancels preheater, by setting preheating section and changeover portion in steam generator, realizes the abundant of heat-source energy
It utilizes, improves economy, and avoid vibration problems caused by steam-water twin phases in preheater.
The present invention, which is suitable for the fields such as electric power, chemical industry, to be needed to generate the heat transmission equipment of steam, should not be especially separately provided
Feed water heater or because load variations wider range needs to avoid the steam generation system for occurring saturation in feed water heater
System.
