一、 锅炉部分
1．超临界压力锅炉                  supercritical pressure boiler
2. 亚临界压力锅炉                 subcritical pressure boiler
3. 超高压锅炉                     super-high pressure boiler
4. 蒸汽锅炉                       steam boiler/A closed tank in which water is converted into steam under pressure.
5. 蒸汽发生器                     steam generator/A closed tank in which water is converted into steam under pressure.
6. 液态排渣锅炉                  wet bottom boiler/ A wet-bottom furnace or wet-bottom boiler is boiler that contains a wet bottom furnace. It is a kind of boiler used for pulverised fuel firing. In wet bottom boiler the bottom ash is kept in a molten state and tapped off as a liquid. Wet bottom boiler slag is a term that describes the molten condition of the ash as it is drawn from the bottom of the slag-tap or cyclone furnaces. An advantage is the fact that the end product in this process has a higher value compared to that of a dry bottom boiler. Wet bottom boilers are preferred for low volatile coals that produce a lot of ash. But it has higher investment costs and higher maintenance costs, so it is built less often.
7. 固态排渣锅炉                   dry bottom boiler
8. 燃煤锅炉                       coal-fired boiler
9. 燃气锅炉                       Gas-fired boiler
                       oil-fired boiler
                   natural circulation boiler/ In a natural circulation boiler the circulation is achieved by the difference in density when the water in the boiler is heated.
（锅筒）锅炉               drum boiler
                   controlled circulation boiler
                       once-through boiler/A boiler in which water flows, without recirculation, sequentially through the economizer, furnace wall, and evaporating and superheating tubes.
