Thermal power plant for non-pelletized grape pomace biomass

Abstract

The thermal power plant uses non-pelletized biomass from grape pomace to heat generation and hot water production . It can burn just as well as wood chips or pellets, but the main purpose of the invention was to use the very large quantities of pomace from the vineyards of the world that are currently not well used profitably and to protect the environment at the same time. The thermal plant is made up of the following main components: -A the rotary burner with self-cleaning which is a constructive and functional innovation; -B the body of the power plant ( boiler) in wich the burner is mounted and contains a pipe system and a water cooling jacke - represents a constructive innovation; -C heat recuperator ; -D battery cyclone-oenofilter and which is a novelty of the filter material; -E ash disposal system. -a Pogrammable Logic Controller unit (PLC) ensures the control of a complete combustion cycle. The biomass burning takes place in a metal cylinder able to resist to high temperatures called the rotary burner basket where temperatures of 600-800 degrees C are reached. The rotary burner basket has thickness of 6-8 mm and holes of 5-6 mm and a cut-out portion (a) the mouth of the basket burner. This can be rotated by 6 π in respect to the the cleanser (10) to be filled with biomass at the beginning of the combustion cycle and empty of ash at the end. The burner can also be used separately from this type of boiler. It is designed to be adapted to other types of thermal plants that used before : wood , pellets, natural gas, diesel etc.It is mounted on wheels together with the PLC and can be adjusted in height to fit ftheir feeding gates. A stainless steel coil (9) heats the air and blows it through the air nozzles in the double walls of the cleaner. The hot air nozzles surround the biomass and increase the efficiency of the process. A feeding auger (2) driven by a gear motor (19) takes the biomass from a tank (1) and transports it to the basket burner (3), The burning of the biomass takes place in a compartment (27) and the hot gases are directed through the water jacket from the boiler body (B) and discharged through the heat recovery pipes (C). The gases cooled to a temperature below 80 degrees C, are discharged by an exhauster with adjustable flow (37) through a cyclone-filter battery (D).This consist of a cyclone (35) and a filter (36) filled of biomass residues resulting from the processing of grapes. Ash evacuation is carried out automatically with the help of a flexible auger (44).
