Abstract:
The NOxOpti project investigated the feasibility of using ammonia-containing biomaterial, cutter-based horse manure, for controlling nitrogen oxide (NO.) emissions in peat combustion. The test runs were conducted at an 8 MW district heating plant, where energy is produced using a fluidized bed boiler. Flue gas control at the site is managed with an electrostatic precipitator. In the experiments, horse manure replaced peat in the total fuel mix at volume ratios of 12%, 27%, and 42%. During the tests, the impact of the biomaterial on the combustion process, material durability, and flue gas emissions was monitored. The results were compared to a reference run using only peat. The fuel samples were analyzed for parameters such as calorific value, sulfur, and chloride content. Additionally, the ash produced during combustion was examined. The test runs demonstrated that adding horse manure to peat reduced NOx emissions by only about 5%. However, the results confirmed that horse manure can be co-fired with peat, enabling more efficient utilization of a by-product unsuitable for fertilizer use.
