Stężenia tlenku węgla i tlenków azotu (NO, NOX) z kotła o mocy 25 kW zasilanego peletami drzewnymi w sposób periodyczny i ciągły. Badano wpływ periodycznego i ciągłego zasilania peletami drzewnymi kotła z paleniskiem nasuwowym-korytkowym, na stężenia tlenku węgla i tlenków azotu (NO i NOx) w spalinach. Stwierdzono, że stężenie tlenku węgla dla zasilania periodycznego rośnie znacząco w stosunku do...
CO, CxHy, NO, NOx and dust concentrations from a cherry stones supplied boiler with a nominal heat output of 15 kW were researched in a heat station. In the entrained flow furnace designed for firing wood pellets, melting and sintering ash phenomenon could not be successfully avoided. In comparison to wood pellet combustion, the observed boiler heat efficiency was lower. CO concentration was relatively...

CO, CxHy, NO, NOx and dust concentrations from a heat station with a boiler of 15 kW nominal heat output supplied with a wood pellet and coffee husk pellet mixture were researched . In the entrained flow furnace designed for firing wood pellet burning, melting and sintering ash phenomenon was not be successfully avoided. In comparison to wood pellet combustion, the observed boiler heat efficiency...
Industrial research of straw ballot combustion in a newly constructed furnace connected with a fire tube steam boiler, type ERm 125, was presented. Four ballots of rape straw and four ballots of wheat-rye straw (dimensions: 1.2 x 0.8 x 2.2 m; weight: approx. 210 kg) were delivered to the furnace one by one with a belt conveyor and burnt out (“cigar combustion”). The entire prototype furnace with a...
W Polsce, odpady płyt drewnopochodnych nie mogą być spalane w kotłach grzewczych i przemysłowych, lecz muszą w specjalnych komorach spalania. Fabryki przemysłu drzewnego nie stosują takich komór, ponieważ są drogie. Termiczne przekształcanie odpadów płyt drewnopochodnych w Niemczech jest możliwe w kotłach o wydajności cieplnej większej od 15 kW, jeśli odpady nie zawierają: PCB (polichlorowane bifenyle),...
Pellets burner was situated in log wood heating boiler of 20 kW thermal output and preliminary investigation was performed. Experimental set-up was located in Poznan University of Technology in laboratory heat station belonged to Institute of Environmental Engi-neering. This heat station can be considered as part of physical model of small district heating system, because is connected (by help of...
Thermal and flow boiler parameters as well as carbon monoxide, nitric oxide, nitrogen oxides NOx and dust concentrations were measured downstream two manual fuel supplied central heating boilers each of 25 kW thermal output (working not in the same time). Construction of these two uncontrolled boilers was not the same, but in both cases wooden waste and waste wood incineration was performed in two...
Thermal utilization of poplar chips, obtained from tree branches sanitary cutting in the city, was conducted in the boiler of 25 kW heat power, which was working with the help of the 900 heat storage. The thermal utilization was carrier out as a two step process: pyrolisis and combustion of wooden gas. Following parameters were measured every three minutes: temperature in pyrolisis zone of the combustion...
The wooden waste thermal utilization study was performed. A mixture of birch and alder bark from plywood factory was utilized in the boiler of 25 kW heat power and 70 l water capacity. The process was performed in two steps: pyrolisis and combustion of wooden gas in the nozzle. The boiler was working without heat storage and therefore sometimes the boiler water temperature increased quickly above...
