| 摘要 |
The invention addresses the problems which are connected to raising and lowering of a furnace bottom or part of bottom in a furnace and/or combustion chamber, whereby the fundamental principles for solving these problems are to direct combustion air in preferably telescopic channels from sources through the furnace and/or the combustion chamber and further through the furnace bottom to the part of the furnace and/or the combustion chamber where the combustion is presently taking place. <IMAGE> |
