Abstract
In this paper according to the calculation of chips productivity needs for gasification in the demo CHP plant for co-generation: electricity and heat, chippers were analyzed due to: the type of mobility, running for chipping and the method of delivering chips to temporary yard. The plant was planned to generate electricity power up to 200kWelec. First, in consideration were taken the chippers with medium capacity, which mainly served for chipping brushwood and leaves that remain after harvest plantations on mostly flat terrain and parks. Later, the comparative characteristics of the world's three largest manufacturers of machinery for the production of wood chips significantly larger amounts (up to 30m3/h) were given. These chippers were particularly suitable for the higher density of crops and stationed yard, in which brushwood would be brought and chip. At the end, the types of convective dryers were analyzed that could be successfully used for drying wood chips (drum and pneumatic dryer) and based on the calculation proposed the types of dryers that were available in the local market.

Имајући у виду поменуту количину сечке од 4275 m3 годишње за континуиран рад нашег демо CHP постројења требало би сакупити грањевину и остали отпадак са око 8-9 просечних шумских етата [5]

Summary
На основу анализе спроведене на територији газдовања шумама газдинства "Сремска Митровица", може се закључити да je реалнa количина дрвног остатка који се може користити за енергетске потребе 28 479,1 m3/god. Према Извештају са пројекта ТР 33049 [4] потребно је 1752 t отпатка годишње за континуиран рад демо CHP постројења снаге 200kWe, које се налази у предузећу “Агросава“ из Шимановаца. Видимо да је ова потребна количина сечке за рад демо-постројења око седам пута мања од расположивог дрвног остатка који се може користити за енергетске потребе на територији газдовања шумама газдинства "Сремска Митровица". Имајући у виду поменуту количину сечке од 4275 m3 годишње за континуиран рад нашег демо CHP постројења требало би сакупити грањевину и остали отпадак са око 8-9 просечних шумских етата [5]. Разматрања око одлагања сечке и концепције избора CHP постројења дато је у радовима [6, 7, 8]
