Opis:
With fossil fuel and supply of centralized energy getting more expensive combined electricity and heating production is spreading in the European Union using cogeneration plants. Such distributed energy generation has a range of advantages: a possibility to use local fuel rationally including fuel of biological nature, lower costs of energy production and distribution, lower environmental pollution and creation of new work places in rural areas. The carried aut analysis showed, that good perspectives are forecasted for using diesel engines in cogeneration plants, if they run on plant oil produced locally. The investigations proved that comparative consumption of mineral diesel fuel made 205š1.4 g/kWh, that of rape seed methyl ester - 225š2.6 g/kWh and plant oil - 230š1.8 g/kWh. The analysis of emissions showed that after changing mineral diesel fuel with pure RME or rape seed oil, a larger amount of NOx is emitted into the environment - 10% and 13% respectively. A comparative amount of CO in oxides while using pure RME decreases by 5.7%, compared with mineral diesel fuel, and using rape seed oil - by 6.3%. Economic calculations showed that capital investments for the erection of a cogeneration plant of 340 kW power would make 480 thou Lt. The operation of such plant would give 448.8 thou Lt of annual income for sold electric power and the production cost of produced heating energy would be 0.18 Lt/kWh.

Opis:
More extensive development of biodiesel production is hampered by a relatively high production cost of this product. Together with external measures (organization of optimal production, minimization of transport costs, etc.) it is necessary to use the by-products of biodiesel as rationally as possible to reduce the production cost. The work deals with the possibilities of using by-products (rapeseed straw, oilcake and glycerol) for energy needs and is based on experiments. The experiments established fractional compositions, thermal properties and dependences of rapeseed oil, oilcake and crude glycerol. Equilibrium moisture content of rapeseed straw, keeping them in a closed room, is 15% and heating value is 17.5š1.9 MJ/kg; the heating value of cold-pressed oilcake with 8-10% of oil is 19.8š2.0 MJ/kg; the water content in green glycerol composition accounts to 12.5š0.6%, the one of methanol is 0.3š0.03_ and their heating value is 22.1š1.7 MJ/kg. The research proved that the use of green glycerol while mixing it with sawdust and pressing is an efficient way to produce fuel. It was established that after adding 80% of crude glycerol to dust, the heating value of dry sawdust increases by 22-23% and the heating value of 8% moisture content sawdust increases by 31-32%. The amount of nitrogen oxides NOx in fume does not exceed the permissible limit - 650 mg/m3, CO amount in fume is minimal as is the amount of free oxygen and only traces of sulphur dioxide are found in the fume.
