Abstract

A boiler designed or retrofitted to produce less greenhouse gasses by using a substantially pure oxygen atmosphere in which to burn fuel. The boiler having a primary burner and water tubes is provided. The boiler further comprises at least one secondary burner located as needed in a zone above the primary burner area and below the boiler steam outlet. The secondary burner providing heat or energy to increase the temperature and quality of the steam. The secondary burner providing the heat or energy lost through the diminished flow rate of exhaust gases through the boiler as a result of the use of oxygen rather than pressurized air.

Description

FIELD OF THE INVENTION

[0001] The present invention concerns steam boilers designed or modified to operate with oxygen and fuel with the absence of normal combustion air and requires a superheated and or reheated steam temperature control employing an advanced method of controlling the superheat and or reheat temperature of steam in the boiler above the conventional combustion region. More particularly the present invention concerns a boiler having at least one additional burner using oxygen and fuel with the absence of normal combustion air in the convection area in order to boost heat and energy at the superheat and or the reheated areas and convection regions as may be required to maintain proper steam temperatures at the outlet of the steam boiler. BACKGROUND OF THE INVENTION

[0002] Power plants and or steam plants used by utility companies, industries and municipalities for, among other applications, the production of steam and electricity, typically comprise small to giant boi...
