An apparatus and method for high velocity injection of a stream of fluid fuel into a stream of NO containing combustion effluents downstream of a primary combustion zone, without the use of recirculated flue gas or other carrier gas. The apparatus includes a fuel introducing member that has a fuel receiving end for receiving fluid fuel from a fuel source and a fuel injection end for injecting the fluid fuel into the stream of combustion effluents. A fuel passage is in fluid communication with the fuel receiving end and the fuel injection end of the fuel introducing member. A means for increasing the velocity of the fluid fuel, without the need of a carrier gas, is associated with the fuel introducing member.

A combustion system for combusting air and fuel includes a primary combustion zone configured to produce combustion gases from the air and the fuel and an intermediate air zone downstream from the primary combustion zone. The intermediate air zone is configured to inject an intermediate air stream into the combustion gases. The combustion system further includes a burnout zone downstream from the intermediate air zone, wherein the burnout zone is configured to inject an overfire air stream into the combustion gases, and at least one hybrid-boosted air injector within at least one of the intermediate air zone and the burnout zone. The at least one hybrid-boosted air injector is configured to substantially simultaneously inject a boosted air stream and a windbox air stream into the combustion gases.

An improved gas flow injector has been developed for use in a combustion system. The gas flow injector has an inner nozzle with tubular configuration for directing a first gas stream to a location distal to the gas flow injector. The inner nozzle has an outlet end portion and a longitudinal central axis. Disposed about the inner nozzle is an outer nozzle having a tubular configuration, for directing a second gas stream to a location proximal to the gas flow injector. A diverter is mounted to the outlet end portion of the inner nozzle and extends at least partially into the second gas stream. The diverter has a surface disposed at an acute angle relative to the longitudinal central axis of the inner nozzle to redirect at least a portion of the second gas stream in a direction transverse to the longitudinal central axis. Also disclosed is a method of injecting a gas into a combustion system using the gas flow injector of this invention.

A pedicure chair is provisioned to receive a separately formed basis or is unitarily formed with a basin. The basin can be equipped with a drain shoe at the drain hole having guide walls and guide slots for readily receiving a stopper to control drainage through the drain pipe. A treatment fluid delivery system can be included to provide treatment fluid to the basin to mix with an amount of fluid in the basin. The treatment fluid delivery system can include a steamer, a secondary fluid product source, and a safety device for regulating flow into the basin. A header or dispenser can be provided within the basin to distribute flow from the treatment fluid delivery system.

A pedicure chair with a basin for receiving a quantity of water therein. An autofill system can be incorporated with the basin to automatically manage spillover. The auto fill system can have a controller, a water supply valve, and a water level sensor. The water level sensor can be a proximity sensor attached externally of the basin. The water level sensor can send a signal to a controller when the water level sensor detects a predetermined water level in the basin. The controller is configured to shut off the water supply to the basin by sending a signal to actuate the water supply valve. A steamer can be used with the pedicure chair to provide heat and a therapeutic steam bath.

A pedicure chair with a basin having an auto-fill system for depositing water into the basin while eliminating spillover is disclosed. The auto-fill system has a controller, a water supply valve, and a water level sensor. The water level sensor can be a proximity sensor attached to an external surface of the basin. The water level sensor can send a signal to a controller when the water level sensor detects a predetermined water level in the basin. The controller can be configured to shut on and off the water supply to the basin by sending a signal to actuate the water supply valve.

An induction heating system for a basin of a pedicure chair and a pedicure chair with one or more pumps and one or more heating sources are disclosed. A conducting object is located on an interior side of a first wall of the basin, with an induction heater located on the exterior side of the first wall. The conducting object is separated from the induction heater by a solid portion of the first wall. The induction heater is configured to generate a high frequency field that passes through the solid portion of the first wall and causes the conducting object to generate heat. A controller is configured to turn on/off the induction heater to maintain a desired temperature in the basin.
