摘要： A furnace firing apparatus and method for burning low volatile fuel in which first (46) and second (66) burners are provided to introduce particulate, air-suspended fuel into primary (Z1) and secondary (Z2) combustion zones of a combustion chamber. The alignment of the second burner is adjustable and aligned so that the stream of fuel and air introduced by the second burner entrains combustion products (E) produced by the burning of fuel in the primary combustion zone in order to ignite the fuel introduced by the second burner. Secondary air is provided by a pair of plenum chambers (48,72) to support combustion of the fuel. In an alternate embodiment, an intermediate burner is provided to entrain combustion products from the combustion of fuel introduced by the first burner and whose combustion products are entrained into the fuel introduced by the second burner.

摘要： A fluidized bed steam generating system in which a duct (16) is disposed between a furnace outlet and a separator inlet. The duct is formed by first and second wall panels (22a, 22b) which are comprised of a plurality of parallel tubes (18) extending perpendicular to the direction of the flow of the combustion gases. The tubes comprising the wall panels are bent and welded to a fin (20) extending from corresponding portions of adjacent tubes to form a gas tight structure. The ends of the tubes are connected in fluid flow communication with first and second headers which enables cooling fluid to flow through the tubes for recovering heat from the combustion gases as they flow from the furnace into the separator.

摘要： A fluidized bed combustion system and method in which a recycle heat exchange section is located within an enclosure housing the furnace section of the combustion system. The flue gases and entrained solids from a fluidized bed in the furnace section are separated and the flue gases are passed to a heat recovery section and the separated particulate material to the heat exchange section. The heat exchange section includes a bypass chamber for permitting the separated solids to pass directly from the separator to the furnace section. A heat exchange chamber is provided in the recycle heat exchange section which receives the separated materials from the bypass chamber and transfers heat from the separated material to a fluid flow circuit. The separated material in the heat exchange chamber is then passed back to the furnace section.

摘要： A corrugated-shaped acoustic baffle unit (12) for insertion into a tube bundle (10) of a tubular-type heat exchanger (13) having parallel staggered tubes to prevent flow-induced vibrations in the heat exchanger (13). The baffle unit (12) is formed of at least two helical-shaped spacer members each rotatably attached to a flexible connecting barrier member, such as a fabric or metal mesh material or formed by multiple adjacent bars or tubes each attached to the rotatable spacer members. The flexible corrugated-shaped baffle unit (12) can be inserted between adjacent parallel tubes of a heat exchanger by rotating simultaneously the helical-shaped members. After insertion of the baffle unit, the ends of the helical-shaped members are connected together so as to prevent their further rotation and thereby secure the baffle unit firmly in place between adjacent tubes of the heat exchanger (13).

摘要： A reactor in which a furnace and a heat recovery area are provided. A bed of solid particulate material including fuel is supported in the furnace and air is introduced into the bed at a velocity sufficient to fluidize same and support the combustion or gasification of the fuel. The products of combustion (or flue gases) pass upwardly through the furnace and transfer heat energy to the walls thereof to produce steam. Flue gases leaving the upper region of the furnace section are transported to a heat recovery area, which functions to remove additional heat energy from the flue gases for producing the steam. A flue gas by-pass system is provided which transports relatively hot flue gases from a lower region of the furnace section to the heat recovery area for improving isothermal operating conditions and optimizing reactor performance. One or more conduits pass flue gases directly from selected extraction points within the lower region of the furnace to an upper portion of the heat recovery area. A dust collector may be connected to the gas extraction conduits for separating particulate material from the flue gases, if needed.

摘要： A seal assembly (60)(62) for a rotating drum (12) in which a trunnion (16) is secured relative to the drum (12) for rotation therewith and is supported by a bearing assembly (18). At least one seal ring (64) engages a shoulder of the trunnion (16) in an area adjacent to the bearing surfaces of the trunnion (16) and the bearing assembly (18). The seal ring (64) is laterally held loosely in place by at least one retaining ring (69) and is biased against the trunnion (16) by a spring loaded cable (78). A lubricant is injected between the trunnion (16) and the bearing assembly (18) and collects in at least one reservoir (46). The lubricant is absorbed by the seal ring (64) from the reservoir (46) through a wick (90).

摘要： A pulverizer for particulate material such as coal includes a housing (12) having a centrally located feed chute (24), and encloses a rotary grinding table (14) having an air port unit formed as multiple segments (32) removably attached to the rotary table outer periphery and containing air flow passageways. Located adjacent the air port unit is an outer segmented ring (40) attached rigidly to the pulverizer housing, with a radial gap (42) being provided between the outer ring and the air port unit ring segments (31). The outer ring segments include upper wear plugs (41) removably attached onto the outer ring lower segments (40a). Whenever the upper parts (31a) of the air port unit segments become worn excessively due to erosion, or there is a need to change air flow requirements of the pulverizer, the rotatable air port segmented ring upper parts (31a) only are conveniently replaced along with the upper wear segments (41) of the adjacent outer stationary ring.
