本文介绍了波兰东北部农业和森林生物质小规模生产型煤的质量和成本。该实验涉及八种类型的压块的生产。最高的净热值是由松木锯屑制成的煤饼（18，144 MJ t（-1））。由多年生能源植物制成的压块的测量值比木屑压块低1500 MJ t（-1）以上，由秸秆制成的压块的测量值比木屑压块低2000 MJ t（-1）。锯末压块留下了最低量的灰分（干质量的0.40%）。氢、硫和氮的显著最高含量发现于含有最高部分的油菜籽油饼的型煤中。压块的质量各不相同，只有一些符合DIN 51731的要求。松木锯屑制成的煤砖质量最高。油菜秸秆压块和油菜秸秆与菜籽饼（50：50）混合压块的生产成本分别为66.55 ~ 137.87 t（-1）。总的来说，除了用稻草和油菜籽油饼混合物制成的煤饼外，秸秆生产是有利可图的。(C)2013爱思唯尔有限公司版权所有。
This paper presents the quality and cost of small-scale production of briquettes, made from agricultural and forest biomass in north-eastern Poland. The experiment involved production of eight types of briquettes. The highest net calorific value was determined for briquettes made from pine sawdust (18,144 MJ t(-1)). The value measured for briquettes made from perennial energy plants was over 1500 MJ t(-1) lower, and for those made from straw 2000 MJ t(-1) lower than for sawdust briquettes. The sawdust briquettes left significantly the lowest amount of ash (0.40% of dry mass). The significantly highest content of hydrogen, sulphur and nitrogen was found in briquettes containing the highest portion of rapeseed oilcake. The quality of briquettes varied and only some of them met the requirements of DIN 51731. Briquettes made from pine sawdust were of the highest quality. The briquette production cost ranged from 66.55 (sic) t(-1) 137.87 (sic) t(-1) for rape straw briquettes and for those made from a mixture of rape straw and rapeseed oilcake (50:50), respectively. In general, briquette production was profitable, except for the briquettes made from a straw and rapeseed oilcake mixture. (C) 2013 Elsevier Ltd. All rights reserved.
