Abstract
The invention objective a Individual Bagasse Drier that realizes a system of utilization of the chimney gases, to decrease the moisture of the bagasse left from the mill in 10 or 15 points, increasing the steam production between 13.5% to 15.45% respectively. It consists of a drier for each furnace, and consumes 54% of the power installed per ton of dry bagasse, in relation to the existing systems in the market.
Claims6
In combination with a furnace for burning bagasse, wherein the furnace includes a fuel entrance and an exhaust for gasses,
- a bagasse heating chamber,
- means for feeding bagasse to said chamber,
- means for supplying heated gas to said chamber,
- a gas-solid separator including an inlet for solid material and gas, an outlet for gas, and an outlet for solid material,
- means for conveying heated bagasse and moisture-laden gas from said chamber to the inlet of said gas-solid separator,
- means for connecting the solid material outlet of the separator to the fuel entrance of said furnace,
- gas impelling means having an inlet,
- means for connecting the inlet of the impelling means to the furnace exhaust for gases,
- means for connecting the inlet of the gas impelling means to the outlet for gas of said separator, and said bagasse feeding means comprising a feeder located above the fuel entrance of said furnace, a conduit extending from the feeder and having branches to the fuel entrance and to the chamber, and a baffle plate blocking the branch to the fuel entrance.
In combination with a furnace for burning bagasse, wherein the furnace includes a bagasse hopper and feeder connected by a conduit with stoker means at the inlet of said furnace, and wherein flue gas is drawn through a conduit to the inlet of a gas impeller, the outlet of which is connected to a chimney,
- a bagasse heating chamber having an inlet for bagasse adjacent said furnace inlet, an outlet, a branch conduit connected to said heating chamber inlet and to the conduit connecting the bagasse feeder with the stoker means,
- a baffle plate blocking the conduit to said stoker means for supplying heated gas to said chamber comprising:
- (a) heating gas conduit means for receiving flue gasses from said furnace and for delivering said flue gasses to said chamber, and
- (b) fan means for driving flue gasses through said heating gas conduit means,
- a gas solid separator having an inlet for solid material and gas, an outlet for gas, and an outlet for solid material,
- conduit means extending downwardly from the solid material outlet to the furnace inlet,
- conduit means extending from the heating chamber outlet to the inlet of the separator, and
- a conduit extending from the gas outlet of the separator to the inlet of the gas impeller.
