Opis:
Nowadays, much attention is paid to the elimination of heat sources poisoning our environment. The air pollution is the most dangerous form of pollution of the environment, due to its direct impact on all living organisms, coverage of large areas and easy movement of pollutants. Therefore, air protection is one of the priority directions of each voivodeship. Hence, many programmes are being developed to promote the replacement of the old heating devices with the new ones and the installation of renewable energy conversion devices. There is no doubt that the equipment which emits the most harmful compounds into the atmosphere includes the old boilers fired with coal, wood or wood chips. In winter, chimneys with black circular smoke are a frequent sight. This problem can only be solved by connecting houses to the public heating network or by removing the old stoves. In this publication, an analysis of the profitability of boiler replacement with coal was carried out in terms of the material and environmental benefits. It is proposed to replace this boiler with a pellet boiler, an eco-pea boiler and a gas condensing boiler. The boilers were selected on the basis of the calculated thermal output, which is equal to 18.56 kW.

Opis:
Solid biomass plays a leading role in the development and dissemination of technologies pertaining to the usage of renewable raw materials. The biomass processed into solid biofuel requires special logistic operations. Distribution from the place of production, handling and storage of biofuel are basic and necessary elements of the chain of fuel supply to the energy source. Solid biofuels for energy use occur in different forms which affect the costs of logistic operations. Rational heat generation requires choosing a specific type and form of biofuel, assessing the availability of raw materials, integrating fuel management with energy source technology and, above all, determining the cost of energy generation. The cost of energy generation includes the cost of fuel and logistic operations, which depend mainly on a type and form of fuel. Currently, the commonly used biofuels are wood chips, straw and pellets. This paper presents a comparison of heat demand of 400 kW, 600 kW and 1 MW boiler plants generating heat for the purpose of heating buildings and water. The analysis took into account three forms of biofuels: compressed, crushed and granulated forms resulting from different types of biomass (straw, woodchips, pellets). The cost of heat generation in the aspect of biofuel management and the share of particular cost components in heat production were determined. It was shown that in medium power boiler plants, the granulated fuel has the lowest cost of biomass distribution, whereas wood chips have the lowest cost of heat production.
