Project summary: Experimental wood fired boiler with underfeed retort was developed and investigated. The combustion mechanisms were studied and operation conditions elaborated.
Main parameters of the experimental unit:
| Nominal capacity: | 100 kW |
| Efficiency: | 83.2% |
| Emission of CO and NOx: | 250-300 ppm under excess air factor of 1.4…1.5 |
| Fuel: | wood chips, saw dust, chaffed straw, peat |
Innovativeness: The retort has extended zone for complete burning of coke-ash rest on grate;
It is possible to combust fuel of low quality (high ash content, up to 45-50% moisture content, irregular fractional composition) and have acceptable emission from the boiler.
