其中，下导电片11右侧外壁与移动杆12连接，移动杆12右端延伸至锅炉本体1的右侧外壁，锅炉本体1与移动杆12的连接部位开设有滑槽，移动杆12外壁设置有外螺纹，移动杆12外壁套接有套管13，套管13与移动杆12的连接部位设置有与外螺纹相匹配的内螺纹，套管13左侧外壁与锅炉本体 1右侧外壁相贴合，拧动套管13，使套管13与锅炉本体1右侧外壁分开，向上或向下移动移动杆12，使下导电片11与上导电片10之间的间距改变，改变叶片6翻动煤粉堆时所需要的温度，从而可以控制煤粉堆翻动时的温度；
热水加热室4左右两侧内壁均匀设置有隔板16，左侧隔板16与右侧隔板16相互交错设置，使含热气体在热水加热室4中按照S形流动，使含热气体停留的时间增加，增加热量的利用效率，减小热量消耗，增加能源的利用效率，隔板16竖截面的宽度由外向内逐渐增加，使含热气体停留的时间更长，进一步提高含热气体的利用效率；
安装槽9右侧内壁开设有限位槽14，移动杆12上下两侧外壁均设置有限位块，限位块位于限位槽14的内腔中，使移动杆12不会左右移动，保证下导电片11位置不会发生偏移，确保装置正常工作；
进气孔15个数共有十五组，且十五组进气孔15呈矩形阵列排布，使含热气体进入到热水加热室4中更加分散均匀，使水加热更加均匀和充分，提高含热气体的利用效率；
导热箱7右侧外壁设置有卡块，燃烧室3与导热箱7的连接部位开设有与卡块相匹配的卡槽，且卡块右端插接在卡槽的内腔，方便将导热箱7拆下来，便于更换导热箱7或者向导热箱7内部添加气体，保证导热箱7正常工作。
工作原理：将煤粉加入到燃烧室3中进行燃烧，燃烧产生的热量传递到热水加热室4中对水进行加热，通过隔板16增加含热气体在热水加热室4中的停留时间，增加热量的利用效率，减小热量消耗，增加能源的利用效率，然后接通电源，当燃烧室3内部的煤粉无法充分燃烧时，燃烧室3内部温度降低，使导热箱7内腔气体体积减小，使移动板带着导向杆8向下移动，从而使上导电片10与下导电片11接触，使电机5通电工作带着叶片6翻动煤粉堆，自动将内部煤粉翻出来，使内部煤粉与空气充分接触，提高煤粉的燃 烧效率和利用率，避免煤粉无法充分燃烧而造成资源浪费，同时也不需要人工定时去翻动，降低工作难度，当燃烧室3内部温度上升时，导热箱7内部气体体积增大，使上导电片10与下导电片11不接触，使电机5与叶片6停止工作。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
