摘要：

Development and construction of a furnace for biomass with system of direct and indirect air heating. A furnace, with a system for direct and indirect air heating, was projected and constructed to use biomass, particulate biomass, abundant and largely wasted agroindustrial refuse, as complementary fuel to firewood. With the objective of verifying furnace operation, in the option of direct and indirect heating, three preliminaries tests were conducted using only firewood as fuel. In these tests, the following variables were monitored: room air temperature, heated air temperature at the exit of the furnace and after the fan; room air relative humidity; warm air flow; lower calorific power and thermal efficiency of the furnace. In the tests the results showed, for both direct and indirect air heating, the furnace was shown to be flexible in the heating option, of easy construction and operation, not requiring skilled labor.
