Title: 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 » 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.« less
