BOILER-UTILISER Russian patent published in 2009 - IPC F23G7/06 F23G5/46 

FIELD: chemistry.

SUBSTANCE: boiler-utiliser is intended for neutralisation and utilisation of smoke gas heat and can be used in coke-chemical, metallurgical, chemical and other branches of industry. Boiler-utiliser contains joining pipe for smoke gas supply, joining pipe for smoke gas output, reactor supplied with cyclone combustion chamber, including burner device, into which tangentially joining pipe for smoke gas supply is joined, system of heat utilisation, which includes heat-exchanging surfaces and is connected with reactor and joining pipe for smoke gas output. Boiler-utiliser is supplied with system of enriching smoke gases with fuel and air, which is connected with joining pipe for smoke gas supply. Reactor additionally contains at least one cyclone combustion chamber and is supplied with chamber of after-burning connected with cyclone combustion chambers and forming together with them working volume of reactor, ratio of after-burning chamber volume to working volume of reactor being determined by the following dependence: 0.43<V₁/V₂≤0.85, where V₁ is after-burning chamber volume, m³; V₂ is working volume of reactor, m³.

EFFECT: ensuring high degree of smoke gas purification from admixtures, as well as increase of reliability of boiler-utiliser work and efficiency of utilisation of heat of smoke gases released from fuel-burning aggregates.
