WDR series electric heating boiler series products belong to high-power steam boiler and hot water boiler, using the furnace body electric control cabinet separation mode, to avoid the electrical components heat aging and affect the service life; Heater choose ceramic electric heating tube, low surface load, long service life; With a single small flange connection, easy maintenance; Its normal service life is about 20,000 hours, the thermal efficiency is nearly 99%, the operation is quiet, clean, in line with the requirements of environmental protection, will not emit NOx (nitrogen oxides) to the atmosphere; The operation part adopts PLC control system, all free operation button, all free indicator light, touch screen panel, Chinese and English display, man-machine dialogue, operation authorization, real-time information, automatic page turning.
1, the use of advanced electric heating tube, each group of electric heating elements using concentrated beam type flange connection, independent setting, with simple structure, high mechanical strength, safe and reliable, easy to replace, its surface load is low, long service life.
2, the boiler starts and stops fast, the operating load adjustment range is large, the adjustment speed is fast, and the operation is simple.
3. The heating element automatically adjusts the number of input groups of the heating tube according to the change of temperature difference and load, and can automatically convert the input order, not only saving energy, but also balancing the running time of each group of heating tubes, so as to uniform the life of the heating tube.
