Description
Technical field
The present invention relates to the technical field of combustion furnace, specifically a kind of sufficient oxygen is even to send air feed combustion furnace.
Background technology
The veneer of timber is the raw material for producing the wood-based plates such as glued board, core-board, thick china, and veneer is generally to use log
Rotary-cut is formed.Because the veneer that rotary-cut goes out contains large quantity of moisture, so could be for producing people after needing to be dried it treatment
Make plate.The traditional drying mode of wood single-plate is that nature dries, and the process duration of this method is long, it is necessary to drying is suitable
The site condition of natural environment and spaciousness, is easily influenceed, it is difficult to be applied to industrialized large-scale production by weather environment.In order to
Overcome the shortcoming that nature dries, people have invented baking oven, drying room or special drying unit is dried, and plank is uniformly distributed
In baking oven or drying room, and keep certain gap, being heated by electrical heating or fuel, so as to be dried plank at place
Reason.At present, most of wood producing producers are all to timber list by the use of useless plate and wood skin as the heat of generation after fuel combustion
Plate is dried, that is, need a kind of hot-blast stove of burning fuel.Open source literature also reports some and is produced using after fuel combustion
The device dried to timber of heat, for example：
