Abstract
The invention discloses a kind of conduction oil and the double medium coproduction CFBBs of water vapour, both in traditional CFBB, on the basis of device of working medium radiation heating-surface, cyclone separator, device of working medium convection heating surface, air preheater are set, conduction oil radiation heating-surface is added in boiler hearth of circulating fluidized bed, conduction oil convection heating surface is added in back-end ductwork.The present invention can not only heat conduction oil simultaneously, produce steam by setting up conduction oil heating surface in CFBB, moreover it is possible to reduce exhaust gas temperature, improve boiler thermal output, improve separate unit boiler heat load.
Description
Technical field
The present invention relates to a kind of heat-conducting oil heating boiler, specifically one kind can heat conduction oil, and and can production water steams
Double medium coproduction CFBBs of vapour.
Background technology
Conduction oil belongs to organic heat carrier, is a kind of excellent heat-conduction medium of low-voltage high-temperature, with steam, hot aqueous medium's phase
Than it has the characteristics that to keep under high temperature (~400 DEG C), and liquid, thermal conductivity factor be big, easy temperature control system.
Current heat-conducting oil furnace is mainly using the combustion systems such as hand fired grate, traveling-grate stoker, moulded coal fire grate, these burning sides
Formula will not only use high-quality bituminous coal, and the thermal efficiency is low, energy waste is serious, separate unit boiler heat load is small.
If the water in existing production water vapour CFBB heating surface or vapor are directly changed to import oil, though energy
Increase the thermic load of separate unit boiler, but boiler still suffers from the shortcomings of exhaust gas temperature is higher, the thermal efficiency is relatively low.
The content of the invention
It is an object of the invention to:By arranging two kinds of working medium of conduction oil and water in CFBB, pot is reduced
Stove exhaust gas temperature, improve boiler thermal output while improve separate unit boiler heat load.
The technical solution adopted by the present invention is:A kind of conduction oil and the double medium coproduction CFBBs of water vapour, bag
Include burner hearth, conduction oil heating surface, device of working medium heating surface, cyclone separator, feeding back device, back-end ductwork and air preheater, institute
The boiler stated uses CFBB, burner hearth arrangement conduction oil radiation heating-surface and device of working medium radiation heating-surface, afterbody cigarette
Arrangement conduction oil convection heating surface inside road;Device of working medium convection heating surface is arranged in back-end ductwork.It is high caused by burning in burner hearth
Warm flue gas in burning bed by radiation of burner hearth heating surface after, cigarette temperature drop is low, into cyclone separator carry out flue dust separation, then
Into back-end ductwork, after back-end ductwork with convection heating surface by exchanging heat, temperature further reduces, and subsequently enters boiler air
Preheater, eventually enter into smoke processing system.
Wherein, both in traditional CFBB, conduction oil radiation is added in boiler hearth of circulating fluidized bed
Heating surface, conduction oil convection heating surface is added in back-end ductwork.
A kind of conduction oil of the present invention is with the advantages of water vapour pair medium coproduction CFBB:Both in tradition
CFBB in, set device of working medium radiation heating-surface, cyclone separator, device of working medium convection heating surface, air preheater
On the basis of, conduction oil radiation heating-surface is added in boiler hearth of circulating fluidized bed, conduction oil pair is added in back-end ductwork
Flow heating surface.
