摘要： A primary air system for a combustion plant provides a flow of primary air to at least one coal pulverizer, which emits pulverized coal in a downstream direction to a furnace. The primary air system includes a first primary air line for feeding hot primary air to the coal pulverizer and a second primary air line for admixing of cold primary air into the hot primary air line at a mixing location positioned upstream of the coal pulverizer. A control system shuts off the flow of primary air to the coal pulverizer, when the coal pulverizer is being repaired or serviced while the furnace is in operation. The control system includes a first flow control butterfly valve disposed in the first primary air line at a position upstream of the mixing location and a second flow control butterfly valve disposed in the second primary air line at a position upstream of the mixing location. A shut-off butterfly valve, disposed in the primary air line intermediate the mixing location and the coal pulverizer, includes a tandem wing supported at a cental location and movable between an open position and a closed position. The tandem wing has parallel, first and second wings forming a space therebetween. A pressure relief line provides fluid communication with the space between the first and second wings when the tandem wing is in the closed position. A pressure relief butterfly valve is disposed in the pressure relief line.

摘要： A boiler assembly including primary and secondary combustion chambers includes primary and secondary air controls for controlling combustion air to the chambers respectively. The air controls are operable between open positions to allow combustion in the chambers and a closed position in which the combustion air passages are fully sealed to fully interrupt combustion responsive to heating demands. The air controls are supported externally on the main housing of the boiler assembly so as to be modular and readily releasable from the main housing and the respective combustion air passages. The primary combustion chamber communicates with the secondary combustion chamber at a location partway in between introduction of the secondary combustion air and the exhaust passage.

摘要： A wireless damper control device comprises a damper positioned in a flue, movable between a closed position where the flue is blocked and an open position, a damper controller which sends a damper signal which moves the damper between the open position and the closed position, and a fire side controller which transmits a fireplace signal to open a gas valve to initiate combustion when a fire is desired at a fireplace, and to close the gas valve to terminate combustion when a fire is no longer desired at the fireplace, and which receives a damper status signal from the damper controller indicating whether the damper is in the closed position or the open position. When a fire is desired at the fireplace, the fire side controller transmits a damper control signal to move the damper to the open position, and the fireside controller transmits the fireplace signal to open the gas valve after receiving the damper status signal indicating that the damper is in the open position, and the fire side controller is wirelessly connected to the flue side controller.

摘要： A hot water heater comprises a valve control unit having a gas inlet, a pilot burner, a main burner and a damper assembly. The damper assembly has a pressure diaphragm, a gearing mechanism and a movable damper. The control unit being coupled to operatively supply gas to the pilot burner, the main burner and the damper assembly whereby when gas is supplied to the damper assembly, the pressure diaphragm is moved to thereby cause the gearing mechanism to move the damper from a first position to a second position.

摘要： The object of the invention is to provide a novel combustion chamber which has an improved air supply and also ensures an optimum incident flow to the burners when the mass flows of cooling and combustion air are different. According to the invention, this is achieved in that the at least one cooling duct (10) is extended right into the plenum (13) and is formed inside the plenum (13) as a diffuser (14) having an orifice (12) leading into the plenum (13). The at least one opening (15, 15') in the burner dome (4) is arranged in the region of the diffuser (14) or directly downstream of its orifice (12). A bypass duct (16, 16') having an orifice (17, 17') leading into the plenum (13) follows downstream of each opening (15, 15'). The orifice (17, 17') of each bypass duct (16, 16') is oriented at least approximately in parallel with the orifice (12) of the diffuser (14) and is also designed so as to be offset step-like to the outside. Each bypass duct (16, 16') is provided with a pressure-regulating device (18, 18').

摘要： The present invention provides a valve and a low pressure drop combustor bypass. The valve simultaneously controls both the supply of air to the premixer, and the amount of air directed into a large bypass duct. Air entering the bypass duct is reintroduced into the gas flowpath as dilution air downstream of the combustion zone. At low power settings the valve directs most of the air to the bypass duct, in effect bypassing the fixed area dilution ports, whereby the pressure drop across the combustor may be controlled at an optimal level.

摘要： According to the present invention, a catalyst combustion apparatus includes a ring-shaped catalyst body for catalytically burning the mixture of the fuel and the air, which is disposed in a combustion cylinder. In the combustion cylinder, a fuel nozzle and an inlet for the air are disposed at one end side of the catalyst body, and the premixing chamber is formed at the other end side. The fuel and the air are supplied from one end side of the catalyst body through a through-hole formed at a center portion of the catalyst body and is mixed in the premixing chamber. In the premixing chamber, a flow direction of the mixture is turned toward the catalyst body. A part of the exhaust gas is introduced into the air at one end side. In this way, it is possible to simplify and downsize the combustion apparatus, while securing the preheating effect of the air by the circulation of the exhaust gas.

摘要： An integral vent damper/hood apparatus for regulating draft in a flue of a hot water heater includes a damper support having a hemispherical dome, a congruent cylindrical portion with a plurality of openings therein for passage of flue gas therethrough, and a bottom support. A coaxial faceted guide is disposed between the hemispherical dome and the bottom support with a flue gas floatable damper disposed between the hemispherical dome and the bottom support and moveable along the coaxial faceted guide in response to flue gas exiting the hot water heater flue. The damper includes a coaxial circular aperture therein for enabling the movement of the damper along the faceted guide with contact occurring only at intersections of the guide facets. A hood is provided for conducting flue gas passing through said damper support into an exhaust flue along with a fixture for coaxially attaching the hood and damper support to the hot water heater flue.
