The article presents the suitability of polish lignite deposits for clean coal technologies, mainly fluidized bed gasification and underground gasification. One of the key elements in this study, is a detailed diagnosis of the resource base, its analysis on the basis of the established verification criteria and -as a result - the achievement of a reliable assessment of suitability for highly efficient production of fuels and electric energy through lignite gasification in both surface and underground installations, taking into account both sozological conditions and protected geological sites. The analysis has shown that only 10 out of from 166 lignite deposit meet the criteria for the potential development of process underground gasification.

“…In accordance with the principles of the standard International Classification of In-Seam Coals (1998) and its supplement the Low Rank Coal Utilization -International Codification System (2002) lignite from the Szczerców deposit is humic orto-lignite (Bielowicz 2012a(Bielowicz , 2012b. According to the average values of the technological parameters of coal, the code for the studied lignite as follows: humic low-rank C (orto-lignite) 19 51 23 33; where: C -low class, which is called the clean coal, 19 -net calorific value on dry ash free basis (here is 18.861 MJ/kg), 51 -average natural moisture on received basis (here is 51.7%), 23 -average ash content on a dry basis (here is 23.6%), and 33 -average sulphur content on a dry basis (here is 3.36%).…”

Bełchatów Lignite Mine is the largest producer of lignite in Poland with estimated coal reserves of 700 million tons. The mine excavates two lignite deposits Bełchatów and Szczerców. The Szczerców lignite deposit occupies the western part of the Kleszczów trough, located in the Polish Lowlands. The main part of the lithostratigraphic profile of the Szczerców lignite deposit is a multilayer coal complex, whose thickness varies from 1 to 180 m, with the overburden ratio of 2.84:1. The average thickness of the balance lignite amounts to 40 m. The carbonaceous coefficient of the coal complex in the predominant part of the deposit is over 70%, but locally reaches even up to 100%.Lignite from the Szczerców deposit is of an average technological quality. It typically contains 51.7% of total moisture, 23.6% of ash on dry basis, 3.36% total sulphur recalculated to dry basis, and a net calorific value of 7.33 MJ/kg. Random reflectance (R 0 ) is 0.27% with huminite group macerals averaging at 85%. According to the International Classification of In-Seam Coals and Low Rank Coal Utlization, the technological code of the lignite from the Szczerców deposit is: humic low-rank C (orto-lignite) 19 51 23 33. Similarities between the quality parameters of lignite from the Szczerców and Bełchatów deposits will allow it to be burned in the Bełchatów lignite-fired power plant and may give a chance to extend its activity after the completion of lignite mining from the Bełchatów deposit.

“…W innym artykule zostały omówione sposoby suszenia niskogatunkowych paliw węglowych [43]. W tym miejscu warto wspomnieć o publikacji, w której zaproponowano klasyfikację niskogatunkowych paliw, ułatwiającą podjęcie decyzji o sposobie wykorzystania paliwa [5]. Przedmiotem przeglądu literaturowego była woda zawarta w niskogatunkowych węglach, z uwzględnieniem jej rodzaju, oddziaływania ze strukturą paliwa i wpływu na proces transformacji w wyższych temperaturach [61].…”
