采用日本真空热水锅炉的制造技术和欧洲的低NOx燃烧技术。Use manufacturing technology of Japanese vacuum hot water boiler and European low NOx combustion technology.
工作原理 Operating principle
真空热水锅炉是利用水在不同的压力下，沸腾温度不同的特性进行工作的。例如：在一个大气压下，水的沸点是100℃，而在6mmHg的压力下，水的沸腾温度则是4℃。真空热水锅炉则是在20mmHg－500mmHg的压力范围内工作的，对应的出水温度为15℃～85℃。在此工作压力下，燃烧使热媒水温度上升至饱和温度，并在水面产生相同的蒸汽。此时向热交换器（供热水或采暖）内通冷水，管内的冷水被管外的蒸汽加热成温水并通至用户处，而管外的水蒸汽则被冷却凝结成水滴滴回水面再被加热，从而完成整个循环过程。Vacuum hot water boiler works according to features under different pressures and different boiling temperatures. For example: water boiling point is 100℃ under one standard atmosphere, while water boiling point is 4℃under 6mmHg pressure. Vacuum hot water boiler works within 20mmHg－500mmHg pressure scope and corresponding effluent temperature is 15℃～85℃. Under this working pressure, combustion makes hot medium water temperature rise to saturation temperature and produce the same steam on the water surface. At this time, feed cold water to heat exchanger (supplying hot water or heating), cold water in the tube flows to the user after heated to be warm water by the steam outside tube, the steam outside tube is cooled to be water dripping on the water surface to be heated again, and thus complete the whole cycle process.
