Abstract
The present invention uses a pivotally mounted damper to cover the port and provide damping to the boiler furnace. The damper is aligned with and superjacent the rodding mechanism and is supported intermediate the port and the pivotal mounting by a linkage which raises and lowers the damper responsive to linear motion of the rodding mechanism.
Claims19
Apparatus for cleaning and damping a port in a boiler comprising:
- (a) means for iteratively urging a reciprocating plunger through at least one boiler port;
- (b) means for damping said port;
- and
- (c) means connecting said damping means and said plunger for automatically displacing said damping means relative to said port responsive to reciprocating motion of said plunger.
Apparatus for cleaning and damping a port in a boiler comprising
- (a) means for iteratively urging a reciprocating plunger through at least one boiler port, comprising a linear actuator operatively connected to said plunger, guide means mounted for reciprocal, concomitant, and parallel motion with said plunger for maintaining alignment of said plunger with said port, and control means for advancing and retracting said linear actuator responsive to a predetermined signal, said control means comprising a timer operatively connected to a source of actuating fluid and said linear actuator to advance and retract said actuator at predetermined intervals, based on operative characteristics of said boiler,
- (b) means for damping said port;
- and
- (c) means connecting said damping means and said plunger for automatically displacing said damping means relative to said port responsive to reciprocating motion of said plunger.
Apparatus for cleaning and damping a port in a boiler comprising:
- (a) means for iteratively urging a reciprocating plunger through at least one boiler port, comprising a linear actuator operatively connected to said plunger, guide means mounted for reciprocal concomitant and parallel motion with said plunger for maintaining alignment of said plunger with said port, and control means for advancing and retracting said linear actuator responsive to a predetermined signal, said control means comprising means for detecting particulate matter entrained in combustible gases in said boiler, means for quantifying the number of particles detected per unit of time and means for activating said linear actuator responsive to a quantity of particles detected per unit of time in excess of a threshold level,
- (b) means for damping said port;
- and
- (c) means connecting said damping means and said plunger for automatically displacing said damping means relative to said port responsive to reciprocating motion of said plunger.
Apparatus for cleaning and damping a port in a boiler comprising:
- (a) means for iteratively urging a reciprocating plunger through at least one boiler port, said means for urging comprising a linear actuator operatively connected to said plunger and guide means for maintaining alignment of said plunger with said port;
- (b) means for damping said port;
- and
- (c) means connecting said damping means and said plunger for automatically displacing said damping means relative to said port responsive to reciprocating motion of said plunger.
In a boiler having a plurality of ports therein for supplying air to a furnace therein, said ports receiving air through a wind box, an improved apparatus for cleaning and damping selected one of said plurality of ports comprising:
- (a) a reciprocating plunger assembly associated with each selected port mounted to said wind box and moving normal to said port;
- (b) a damper pivotally mounted to said wind box proximal said plunger;
- and
- (c) connecting means operatively connecting said damper to said plunger assembly for concomitant movement of said damper relative to said port responsive to reciprocal movement of said plunger assembly such that said damper and said plunger are mutually exclusively positioned proximal said port.
In a boiler having a plurality of ports therein for supplying air to a furnace therein, said ports receiving air through a wind box, an improved apparatus for cleaning and damping selected one of said plurality of ports comprising:
- (a) a reciprocating plunger assembly associated with each selected port mounted to said wind box and moving normal to said port, said plunger mounted to said wind box by a mounting flange having an aperture therethrough to accommodate said plunger, said mounting flange also having formed thereon a sleeve for receiving therein a pivot pin aligned perpendicular to the direction of motion of said plunger, said pivot pin supporting said damper,
- (b) a damper pivotally mounted to said wind box proximal said plunger;
- and
- (c) connecting means operatively connecting said damper to said plunger assembly for concomitant movement of said damper relative to said port responsive to reciprocal movement of said plunger assembly such that said damper and said plunger are mutually exclusively positioned proximal said port.
In a boiler having a plurality of ports therein for supplying air to a furnace therein, said ports receiving air through a wind box, an improved apparatus for cleaning and damping selected one of said plurality of ports comprising:
- (a) a reciprocating plunger assembly associated with each selected port mounted to said wind box and moving normal to said port;
- (b) a damper pivotally mounted to said wind box proximal said plunger, wherein said damper comprises a damper plate of sufficient size to obscure said port when placed in registry therewith and support members rigidly affixed to and extending from said damper plate to a pivotal connection with said wind box, said damping plate, support members and pivotal connection being positioned such that pivotal motion about said connection moves said damping plate between a port closed position and a port clear position, and
- (c) connecting means operatively connecting said damper to said plunger assembly for concomitant movement of said damper relative to said port responsive to reciprocal movement of said plunger assembly such that said damper and said plunger are mutually exclusively positioned proximal said port.
