Abstract: This invention relates to a boiler (1) drying, igniting and combusting refuse and producing steam (2, 2a) by heat exchange with flue gases (3), said boiler defining a main flow direction (5) of gases, said boiler (1) comprising a separator element (4) and an end superheater (8), the separator element (4) being adapted for separating said flue gases (3) into streams of a less-corrosive gas flow (6) and a corrosive gas flow (7), said separator element (4) being located substantially in and along said main flow direction (5), said end superheater (8) being located in proximity to said separator element (4) and in the flow (6) of said less-corrosive gas. Said separator element (4) comprises a plate (4a) or a wall (4b), which in a number of said separator elements (4) forms a channel as another separator element. This provides for an increased lifetime of said superheater and makes the boiler provide a high and efficient electrical power output.

Abstract: A screw press separator is provided herein for separating and deliquifying a slurry of solids and liquids e.g., a slurry of manure and water, or any other slurry of similar physical characteristics. The separator includes a cylindrical housing having a slurry inflow port. A cylindrical strainer basket extends rearwardly from the housing for the passage of separated liquid therethrough. A cylindrical discharge chamber extends rearwardly from the outlet end of the strainer basket to define a solids discharge opening. A motor driven auger is disposed within the housing and the strainer basket, the auger including a shaft extending through the housing, through the strainer basket and through the cylindrical discharge chamber, for driving the auger for advancing the slurry rearwardly within the cylindrical housing. A spring-loaded door assembly which is connected to the shaft, is provided at the exit of the cylindrical discharge chamber.

Abstract: This invention is concerned with a removable filter to prevent the buildup of Creosote in chimneys which become vulnerable to fires.A hollow enclosure means that is adapted to connect between the chimney and the fire source has within it a support for mounting a filter. The filter is made of a special metal, is knitted with small openings therein permitting the flow of smoke but at the same time to reduce the particles into a minute white ash. The filter acts as a continuous burn reactor. A door is provided whereby the filter can be easily removed from the hollow enclosure and cleaned so that it can be used for an indefinite period without replacement.
