Supercritical downshot boiler

Abstract

A downshot boiler for heating water comprising a first combustion chamber; at least one tube for transporting water, each tube being at least partially located at the first combustion chamber, heating means for heating the first combustion chamber, the heating means comprising a downshot burner, wherein the boiler is adapted to heat the water to a supercritical condition. A method of heating water comprising the steps of transporting the water within at least one tube to a first combustion chamber provided in a downshot boiler and heating the first combustion chamber using a downshot burner such that the water within each tube is heated to a supercritical condition.

1 . A downshot boiler for heating water comprising 
 a first combustion chamber;    at least one tube for transporting water, each tube being at least partially located at the first combustion chamber; and    heating means for heating the first combustion chamber, the heating means comprising a downshot burner,    wherein the boiler is adapted to heat the water to a supercritical condition.    
     
     
         2 . The downshot boiling for heating water as recited in  claim 1  wherein each tube includes a substantially linear portion.  
     
     
         3 . The downshot boiler for heating water as recited in  claim 1  wherein each tube includes a substantially vertical portion.  
     
     
         4 . The downshot boiler for heating water as recited in  claim 1  wherein each tube includes either a substantially linear portion and a substantially vertical portion.  
     
     
         5 . A method of heating water comprising the steps of 
 transporting the water within at least one tube to a first combustion chamber provided in a downshot boiler; and    heating the first combustion chamber using a downshot burner such that the water within each tube is heated to a supercritical condition.
