1、一般水冷壁回路均由不受熱的下降管和作為上升管的受熱水冷壁管構(gòu)成，下降管從上鍋筒將爐水經(jīng)集箱引入水冷壁，下降管和水冷壁管的上端和上鍋筒脹接或焊接，下端和下集箱焊接，爐膛中部的斜管束為對(duì)流蒸發(fā)受熱面管束。
General wall circuit by the unheated down pipe and a rising pipe as the water wall tube, down tube from the upper boiler barrel water collecting box into the furnace water wall tube, the upper end and the decline of water wall tubes and the upper barrel expansion or welding, and the lower end of the lower header welding, oblique the tube bundle in the middle of the hearth for the convective evaporation heat exchange tubes.

2、多次強(qiáng)制循環(huán)電蒸汽鍋爐http://www.scsuntao.cn/的水冷壁均為垂直上升管屏，其結(jié)構(gòu)與自然循環(huán)鍋爐的水冷壁結(jié)構(gòu)相似。
Water cooled wall repeatedly forced circulation electric steam boilers are vertical upward tube screen, water wall structure and the structure of natural circulation boiler similar.

3、電蒸汽鍋爐受熱面的高溫腐蝕及發(fā)生在煙溫>700℃的區(qū)域內(nèi)，布置在爐膛火焰中心區(qū)的水冷壁管金屬與含硫高溫?zé)煔饨佑|會(huì)發(fā)生水冷壁管的高溫腐蝕減輕這類腐蝕的方法有各燃燒器中燃料和空氣分配均勻；火焰不直接沖刷管壁；過量空氣系數(shù)不宜過小；采用添加劑和應(yīng)用滲鋁管作為水冷壁等。
Electric steam boiler high temperature corrosion of heating surface and occurred in the smoke temperature of >700 DEG C area, method of metal and sulfur of high temperature flue gas contact will occur high temperature corrosion of water wall tube to alleviate this kind of corrosion of the water wall is arranged in the furnace flame center area of the pipe with the fuel and air distribution of the burner flame uniform; not to directly flush the pipe wall; excess air coefficient should not be too small; the use of additive and application of aluminizing pipe as the water wall.

4、在電蒸汽鍋爐http://www.scsuntao.cn/中,根據(jù)用戶需要也可裝設(shè)過熱器,但汽溫一般不超過400℃，過熱器可根據(jù)布置位置和傳熱方式分為幾類，工業(yè)鍋爐的過熱器均為對(duì)流式過熱器，現(xiàn)代大型電站鍋爐的過熱器則常由對(duì)流式，半輻射式和輻射式過熱器組成。
In the electric steam boiler boiler, according to user needs can also be installed steam temperature of superheater, but generally not more than 400 DEG C, superheater can be according to the arrangement position and mode of heat transfer is divided into several categories, industrial boiler superheater are convection superheater, the modern large-scale power plant boiler superheater is often by convection, radiation and a half radiant superheater composition.
