Definitions

  • ABSTRACT F THE DISCLUSURE This invention is directed to a liquid fuel burner comprising a burner nozzle having an inlet end and a discharge end portion for providing an unimpeded flow path therethrough for the fuel mixture.
  • a means defining a gasifying chamber is operatively connected to the burner nozzle for effecting gasification of the liquid fuel introduced thereinto.
  • the heat for effecting gasification of the liquid fuel in the gasification chamber is effected by providing a plurality of port openings spaced inwardly and adjacent the discharge end portion of the burner nozzle so as to effect recirculation of a portion of the products of combustion generated in or at the burner nozzle to the gasification chamber.
  • a mixing chamber Disposed in communication between the gasifying chamber and the inlet to the burner nozzle is a mixing chamber having a restrictor formed therein. Accordingly, combustion air is introduced into the mixing chamber whereby the flow of air through the restrictor induces a natural circulation to enhance the mixture of the combustion air with the gasified fuel and which creates a zone of reduced pressure adjacent the circulating ports thereby permitting the same to function as a means for retaining the fiame adjacent the discharge end of the burner nozzle.
  • This invention relates in general to a burner construction, and more specifically to a burner construction arranged to gasify a liquid fuel prior to burning to provide for a more intimate and homogeneous mixture of fuel and combustion air; and thereby achieve a more complete and elicient combustion of the fuel.
  • impellers To further enhance the intimate mixing of the atomized fuel particles with combustion air, means in the form of impellers have also been utilized in conjunction with the atomizing means to impart a whirling or swirling action to the atomized fuel and air.
  • impellers While such impellers have been somewhat successful in effecting a more thorough mixing of the atomized fuel with the combustion air, they introduced into the art of combustion additional problems, such as noise and flame instability. Consequently, unless the velocities, which the impellers imparted to the swirling fuel and air, were carefully regulated or controlled, the flame would tend to be blown away from the tip of the burner and thus result in a burner flame-out, which unless quickly detecte ed could and did create serious hazardous conditions in the system in which such burner was used.
  • Another object of this invention is to provide a burner construction in which a portion of the products of combustion generated by the burner are recirculated so that the heat of the combustion gases is utilized to effect gasification of the liquid fuel supplied to the burner.
  • Another object of this invention is to provide a liquid fuel burner constructed and arranged in a manner in which fiame stability is greatly enhanced and in which noise is substantially minimized.
  • Another object of this invention is to provide a burner construction in which the liquid fuel supplied thereto is gasied and intimately mixed with combustion air to form a homogeneous fuel mixture in a manner in which prohibits the condensation of the gasifed fuel.
  • Another object of this invention is to provide a burner construction in which preheated combustion air is intimately mixed with the gasified fuel to form an optimum combustible fue] mixture that is totally consumed to effect a complete and efficient combustion of the liquid fuel.
  • Another feature of this invention resides in the provision of a liquid fuel burner in which the liquid fuel is gasified prior to burning and which is relatively simple ⁇ in structure, that can be inexpensively fabricated, and which is positive in operation.
  • Another object of this invention is to provide a liquid fuel burner in which the liquid fuel supplied thereto is quickly gasified prior to the combustion thereof.
  • Another object of this invention is to provide in a liquid fuel burner means for retaining and stabilizing the flame adjacent the discharge end of the burner nozzle.
  • Another object of this invention is to provide in a liquid fuel burner an arrangement which creates a natural recirculation of a portion of combustion gases through the burner to create adjacent the tip end of the burner an area of reduced pressure that functions to retain the flame thereat.
  • a burner construction comprising a means defining a burner nozzle operatively associated .3 with a gasifying chamber. Liquid fuel is supplied to the gasifying chamber. By subjecting the liquid fuel in the gasifying chamber to heat, the liquid fuel therein is transformed into its gaseous state.
  • the liquid fuel during burner operation is gasied by recirculating a portion of the combustion gases generated by the burner through the gasifying chamber.
  • the heat of the combustion gases is utilized to transform the liquid fuel into its substantially gaseous state within the gasifying chamber.
  • the gasifying chamber is remotely disposed with respect to the burner nozzle and is connected to the nozzle by suitable conduit means, through which a portion of the combustion gases is drawn off and circulated therebetween.
  • the gasfying chamber is disposed in heat transfer relationship with the burner nozzle with suitable port openings interconnecting the burner nozzle into direct communication with the gasifying chamber to provide for the circulation of combustion gases therebetween.
  • a means for mixing combustion air with the gasified fuel and recirculated combustion gases mixed therewith to form a homogeneous combusti le fuel mixture.
  • the mixing of the combustion air with the gasied fuel mixture is attained in a mixing chamber adjacent the inlet to the burner nozzle by passing the air through a Venturi-like restrictor which is open in communication with the gasifying chamber.
  • a negative or reduced pressure zone created thereat causes the gasied fuel to flow from the gasification chamber to the burner nozzle and to mix with the air flowing thereinto to define the combustible mixture which is delivered to the burner nozzle.
  • the combustion air may be preheated by first passing the combustion air through an air heater, e.g.
  • an air heater means disposed in a heat exchange relationship to the burner nozzle. Because the recirculating means of the combustion gases are connected into direct communication with the gasifying chamber, the differential in pressure resulting from the flow of air through the restrictor induces a natural recirculation of a portion of the cornbustion gases from the burner nozzle to the gasifying chamber associated therewith. Accordingly, a low pressure area is created adjacent ports through which the combustion gases are drawn from the burner nozzle and recirculated to the gasification chamber. Preferably, these ports are disposed adjacent the discharge end of the burner so that the area of reduced pressure created thereat functions to retain and/or stabilize the flame at the burner tip during burner operation. Accordingly, as the load of the burner is increased, the greater becomes holding characteristics of the flame adjacent the discharge end of the burner nozzle.
  • a means may also be provided for supplying an auxiliary fuel, as for example a gaseous fuel to the burner nozzle to render the burner readily compatible for burning either liquid fuel and/ or gaseous fuel.

  • a Valve or control 22 is interposed into the liquid supply conduit 21.
  • the gasifying chamber 14 in turn is provided with an outlet 23, connected by a suitable conduit 24 to a fixture 25 which defines a chamber in which the gasified liquid fuel is mixed with combustion air supplied to the mixing chamber 25 through a Venturi-like orifice or restrictor 26 whereby the air and gasied fuel are intimately mixed to define a homogeneous combustion mixture.
  • the liquid fuel supplied to the gasifying chamber 14 is gasified by imparting heat thereto. This is attained by circulation in direct heat transfer with the liquid fuel of the heated product of combustion generated by the burner 1f).

Accordingly, the air supplied through the air heater 30 by a suitable fan or blower is ejected in a heated state through the Venturi-like restrictor 26.
  • the orifice 26 is such that the velocity of the air increases as it flows through the Venturi restrictor, thus creating the pressure differential in the mixing chamber 25 which influences the flow of gasied fuel from the chamber 14 to the burner imparting a considerable velocity to the combustion air-fuel mixture extending past the ports 27a, and also inducing the recirculation of the products of combustion through the recirculating passageways 27 of the burner block to the gasifying chamber 14.
  • a suitable valve 34 is disposed into the air supply line 31 controlling the flow of ⁇ air through the preheater means 30. As shown in FIG. 2, the valve 34 for controlling the flow of air through the preheater 30 is illustrated in the outlet end o-f the preheater 30.
  • a suitable valve may be also interposed into the gas recirculating line 27 to proportion or control the amount of combustion gases recirculated to the gasifying chamber.
  • the amount of combustion gas that is circulated is the amount sufficient to maintain the temperature within the gasifying chamber in a range which is greater than the gasifying temperature ⁇ of the liquid fuel, but less than the cracking temperature thereof. Accordingly, a temperature range of 600 F. to 900 F. is considered to be the optimum temperature range to ⁇ be maintained in the gasifying chamber 14 to effect the desired gasification of the liquid fuel.
  • the temperature of the preheated air is such as to prohibit con densation of the gasifled fuel when the air is mixed therewith in the mixing chamber 25.
  • valve 22 controlling the flow of liquid fuel to the gasifying chamber, and valve 34 controlling the air flow through the air preheater 30 are proportioned in accordance to a desired flame setting.

Accordingly, it has been noted that the recirculating combustion gases effects gasication of the liquid fuels in an atmosphere containing insufcient air to support combustion. Consequently, because of the insufciency of air within the gasifying chamber 14, the danger of flashback is all but eliminated.
  • the arrangement is such that it is rendered readily compatible for operation with a gaseous fuel. Accordingly, whenever a natural or artificial gas fuel is desired to be utilized in the burner as an alternate fuel, an auxiliary fuel inlet may be provided for introducing the gaseous fuel into the gasifying chamber or directly into the mixing chamber wherein it is then subsequently mixed with the air introduced into the mixing chamber.
  • the burner construction described can thus be made readily compatible for burning either a liquid or gaseous fuel separately and/ or in combination. Consequently, separate and distinct burner spuds or nozzles for respective gas or oil fuels are not necessary as heretofore required. Thus, either a gas or liquid fuel may be burned in the same burner nozzle with substantially equal efficiency.
  • the recirculated products of combustion have a catalytic like effect on the combustion of the liquid fuel. This is attributed to the fact that condensation of the gasified fuel is minimized during operation. Also, by utilizing the recirculated products of combustion, the response to the gasification of the fuel in the gasifying chamber is rendered more immediate since the time interval necessary to bring the heating medium up to the temperature necessary to effect gasification of the liquid fuel is reduced to a minimum. Also, the recirculation products of combustion, as the heating medium for effecting the gasification of the liquid yfuel in the gasifying chamber minimizes the danger of flashback because of the low oxygen contents in the chamber. Accordingly, the burner described is relatively simple in structure, positive in operation.
