| 中文摘要: |
| 角管式燃煤锅炉以其优良的结构和良好的运行性能，在我国工业领域中得到了广泛应用。随着环保要求的提高，许多中心城区已不允许燃烧煤炭。由于环保改造的需要，北京淘汰了数以千计的燃煤锅炉，采购了大量燃用天然气的锅炉，被淘汰的燃煤锅炉中不乏角管式燃煤锅炉。以70 MW角管式燃煤锅炉改为燃天然气锅炉为例，介绍了角管式燃煤锅炉的环保改造的方法，不但降低了投资费用，而且对原有锅炉起到了“环保利旧”的效果，同样具有节能减排的功效。 |
| 英文摘要: |
| The coal-fired corner-tube boiler has been widely used domestically due to its excellent structure and good operation performance. With the increasingly high demand for environmental protection, burning of coal has no longer been allowed in many urban districts. As the need for environmental protection, the city of Beijing has abandoned thousands of coal-fired boilers and purchased large quantities of boilers for natural gas firing. Many of the coal-fired boilers abandoned are corner-tube boilers. In this paper, the method for converting coal-fired corner-tube boilers to use of natural gas was described by a case study of a 70 MW corner-tube boiler. Using this method, the original coal-fired boiler can be modified to firing natural gas, and the initial costs can be reduced. |
