The experience of burning the high-moistured waste of biomass conversion
Abstract
Industrially developed countries have a large stock of operating boiler plants to utilize timber industry waste materials (bagasse, bark, wood chips, hydrolytic lignine, sawdust, etc.) for biogenesis of energy. Standard combustion methods employing a bed or flare process cannot guarantee a reliable and economic boiler plant operation with abruptly changing biomass characteristic features. The moisture content in bark or lignin can vary from 50 to 75% during an hour. Particle sizes can vary from powdered to very large, and can have a hundred thousand times size difference. Large metal and mineral inclusions into the starting fuel also complicate the process. The low-temperature whirling combustion technology developed in Russia was taken as a basic. An economical and stable operation of boilers has been achieved by means of up-to-date vortex chamber aerial dynamics, the use of unique devices of fuel feed and preparation with screening the waste materials into sizes. The firing chamber is equipped with a multi-chamber device where screening and fuel particles preparation with the removal of noncombustible inclusions take place. At presenting the firing chamber with multi-step process of burning is in operation with 20 boilers. The firm {open_quotes}POLYTECHENERGO,{close_quotes} a developer and producer of such equipment, carries out themore »

The firm {open_quotes}POLYTECHENERGO,{close_quotes} a developer and producer of such equipment, carries out the modernization of the boiler plant without changes in the its thermal circuit. In most of cases no replacement of draught means is needed. Competitive with the proposed low-temperature whirling technological process can be only a fluidized bed process, but due to the complexity in service, low reliability, high energy expenditures, such chambers at present are very few. The capital expenses one existing boilers updating for a fluidized bed process exceed the expenses on a low-temperature whirling process by 15--20 fold.},
