Over recent years a comprehensive package of actions has been approved, to prevent climate change and to provide reliable and sufficient energy supply. the most important renewable energy source is biomass called Briquettes Produced by Briquetting Press Technology. Biomass is used for energy purposes in the process of direct combustion (wood, straw, energy crops), converted to fuels.
Solid biomass includes organic, non-fossil material of biological origin, which can be used as fuel to produce heat or to electricity generation. The basic solid fuel generated by Briquetting Machine from biomass is:
�’ forest biomass (firewood) in the form of chunks, round timber, chips, briquettes, pellets,
– waste from forestry, wood and paper industry, i.e. branches, poles, thinning, shrubs, brush-wood, root wood, bark, sawdust, black liquor,
�’ a separate group consist of agricultural biomass fuels from energy crops (fast-growing trees, dicotyledonous perennials, perennial grasses, energy cereals),
�’ organic remnants from agriculture and horticulture (e.g. wastes from horticultural production, animal manure, briquettes and pellets of straw, etc.).
The need to increase energy production from renewable sources leads to an increase in demand for agricultural raw materials used for energy purposes. Increased demand for these products has a significant effect on agricultural and energy markets, and moreover it changes scope and intensity of agricultural land use Nowadays, there is public discussion about what is the possible use of agricultural resources for energy purposes, and how to use them.
The most important way to convert biomass is Briquetting Press Technology. An important type of biomass, used by energy and heat manufacturers are biomass briquettes from agricultural sources (agro biomass). Also noticeable is the increase in demand for this type of products among consumers, who use them as fuel. Thanks to this situation, the number of Briquette Plant Project Manufacturer is still growing.
The main aim of this work is to estimate the cost of production of fuel briquettes made from different types of solid biomass. The study was conducted on the basis of the data and the production process. The study analyses the cost of production of fuel briquettes manufactured from grain and rapeseed straw, which is the remnant of agricultural production, and which use for energetic purposes steadily increases, and also on the basis of sawdust. In addition, the work attempts to assess the impact of too high biomass moisture on the production costs of biomass briquettes. Moisture of briquetted material is an important factor influencing the technologic and logistic processes
Compacting or otherwise densification of biomass (through briquetting, pressing or pelleting) is performed, due to its unfavorable physicochemical properties, which hinder its use for energy purposes. This is due, among others with too low bulk density of biomass, which makes it difficult to transport, storage and dispensing for boilers. In addition, a wide range of moisture, hygroscopic properties and low calorific value per unit volume cause difficulties in the distribution of biomass in the primary (original) form. Through the use of the above-mentioned processes, which are subjected to biomass, increases its density, water content decreases and increases the concentration of energy per unit volume of biofuels.
