Industrial gas burner package

Abstract

An integral industrial burner package has been described. The burner housing includes a blower housing integral to the burner housing for housing a blower motor and fan. Burner components are mounted on the blower housing and are cooled by blower inlet air flowing over the components. The blower output air flows through a collection chamber integral to the housing and into an air conduit formed within the burner housing. A fuel conduit is provided within the air conduit and is connected to a nozzle internal to a combustion chamber where the fuel and air is mixed and ignited.

         2 . The integral industrial burner system of  claim 1  further comprising a flame safety module for monitoring burner flame, the flame safety module attached to the blower housing.  
     
     
         3 . The integral industrial burner system of  claim 1  wherein the burner system housing further comprises a cover having an air filter opening for receiving an air filter, the air filter opening located in an air flow inlet path of the blower.  
     
     
         4 . The integral industrial burner system of  claim 1  further comprising a pressure switch mounted on the blower housing.  
     
     
         5 . The integral industrial burner system of  claim 1  wherein the burner housing further includes a radially increasing collection chamber connected to the blower housing, the collection chamber receiving the air flow output.  
     
     
         6 . The integral industrial burner system of  claim 5  wherein an axis of the collection chamber is perpendicular to an axis of the combustion chamber.  
     
     
         7 . The integral industrial burner system of  claim 1  further comprising a mounting flange on an end of the fuel conduit for mounting the electronic fuel control valve.  
     
     
         8 . The integral industrial burner system of  claim 1  wherein the blower is driven at variable speeds via a variable frequency drive and the electronic fuel control valve is modulated to regulate fuel flow to the burner nozzle, the modulation of the electronic fuel control valve being related to the variable frequency drive to provide a selected fuel to air mixture.  
     
     
         9 . An integral industrial burner package comprising: 
 a burner system housing having a blower housing integrally formed therewith, the burner system housing having an air conduit and a fuel conduit, the blower housing connected to a radially increasing collection chamber that opens into the air conduit;    a combustion chamber attached to the burner system housing;    a nozzle mounted in the air conduit and extending into the combustion chamber, fluidically connected to the air flow output and adapted to convey gas fuel and air for combustion, the nozzle connected to the fuel conduit;    a blower mounted within the blower housing, the blower comprising an electrical motor and a fan for generating an air flow output, the blower positioned below the air conduit; and    an igniter mounted on the blower housing for igniting gaseous fuel and air.    
     
     
         10 . The integral industrial burner package of  claim 9  further comprising a fuel control valve interposed in the fuel conduit for regulating gaseous fuel flow to the nozzle.  
     
     
         11 . The integral industrial burner package of  claim 9  wherein the igniter is mounted on the blower housing proximate the nozzle.  
     
     
         12 . The integral industrial burner package of  claim 9  further comprising a flame safety module mounted on the blower housing, the flame safety module monitoring at least one parameter of a flame produced when the gaseous fuel and air is ignited.  
     
     
         13 . The integral industrial burner package of  claim 12  further comprising a fuel control valve interposed in the fuel conduit for regulating gaseous fuel flow to the nozzle and wherein the fuel control valve shuts off gaseous fuel flow if the flame safety module detects that the parameter of the flame is outside limits.  
     
     
         14 . The integral industrial burner package of  claim 9  further comprising an airflow actuator mounted to one of the blower housing and collection chamber.  
     
     
         15 . The integral industrial burner package of  claim 14  further comprising a pressure switch mounted to the blower housing.  
     
     
         16 . The integral industrial burner package of  claim 9  wherein the burner system housing further comprises a mounting flange for mounting the burner system housing.  
     
     
         17 . The integral industrial burner package of  claim 9  wherein the burner system housing further comprises a cover having an air filter opening for receiving an air filter, the air filter opening located in an air flow inlet path of the blower.  
     
     
         18 . The integral industrial burner package of  claim 9  further comprising: 
 a flame safety module mounted on the blower housing, the flame safety module monitoring at least one parameter of a flame produced when the gaseous fuel and air is ignited;
