摘要:
The afterburner plates set includes at least two fire-proof plates (1,2,3,4) made of concrete, providing a heat accumulator and carrier. The concrete plates (1,2,3,4) are placed horizontally. The top plates (2,3,4) are located above the bottom plate (1). The bottom plate (1) is provided with a through opening (5), whilst the top plate (2) is located above the top plate (1) and covers the aforementioned through window (5). The top plates (2,3,4) are shorter than the bottom plate (1) and have their bottom surface formed as parallel ridges (11) separated by grooves (12). The central heating boiler has a body with flow-connected water compartments (15), wherein the front wall (13) of the boiler is provided with an inspection door (16), whilst a retort (7) is provided in the bottom part of the both. Labyrinth-type partition elements (19) of the heat exchanger are located in the top part of the interior of the boiler, above the horizontal partition wall (18). A flue gas inlet duct leading to the heat exchanger is installed between the rear edge of the horizontal partition wall (18) and the rear wall (14) of the boiler. The concrete plates set (1,2,3,4) includes plates placed horizontally one above another.
摘要:
An oxygen fired fluidized bed combustor system (Oxy-FBC) is provided. The system provides means of producing a nearly pure stream of carbon dioxide for storage at high efficiency by controlling the oxygen content within certain regions of the combustor to control the rate of heat release allowing efficient transfer of heat from the combustor to the boiler tubes while avoiding excessively high temperatures that will cause ash melting, and simultaneously remove sulphur from the combustor via sorbents such as limestone and dolomite. The present invention utilizes a coarse oxygen carrier bed material to distribute heat and oxygen throughout an Oxy-FBC, while injecting fine sulphur sorbent that will continuously be removed from the bed.

The burning equipment comprises: a burning chamber having a top plate section (2a) and a bottom plate section (2b); a first burn-promoting plate (30a) being extended downward from the top plate section (2a), the first burn-promoting plate (30a) dividing the burning chamber into a primary burning chamber (10) and a secondary burning chamber (20), the first burn-promoting plate (30a) having a plurality of through-holes (31); and an air outlet (21) being provided to the secondary burning chamber (20). The air outlet (21) is provided to the top plate section (2a). At least one second burn-promoting plate (30b) is extended downward from the top plate section in the secondary burning chamber (20), the second burn-promoting plate (20) divides an opening of the air outlet (21), the second burn-promoting plate (30b) also has a plurality of through-holes (31).
摘要:
Die Erfindung bezieht auf eine Heizeinrichtung, insbesondere Heizkessel, mit einem Brennraum (1) zur Verbrennung von festem Brennstoff, insbesondere Biomasse, sowie einem anschließenden Rauchgaskanal (4) zur Abfuhr von Rauchgasen, wobei in den Rauchgaskanal (4) abwärts gerichtete Wärmetauscherrohre (5) eines Kondensationswärmetauschers münden, deren untere Enden jeweils in einen Abgabebereich (6) für das Kondensat münden. Erfindungsgemäß wird vorgeschlagen, dass im Inneren der Wärmetauscherrohre (5) jeweils ein zum jeweiligen Wärmetauscherrohr (5) koaxial angeordneter Verdrängungszylinder (14) vorgesehen ist, und zwischen der Innenfläche des Wärmetauscherrohres (5) und der Außenfläche des Verdrängungszylinders (14) jeweils ein schraubenfederförmig mit einem Windungsabstand A ausgeführter Verwirbelungskörper (15) angeordnet ist, wobei der Verdrängungszylinder (14) und der Verwirbelungskörper (15) in axialer Richtung des jeweiligen Wärmetauscherrohres (5) um eine Hubhöhe H, die dem Windungsabstand A entspricht oder ihn übersteigt, beweglich gelagert sind. Auf diese Weise wird eine dauerhaft effiziente Übertragung der Verbrennungswärme fester Brennstoffe auf das Wärmeträgermedium mithilfe von Kondensationswärmetauschern sichergestellt.
