Prikaz koncepcije rešenja postrojenja za dobijanje biogoriva u obliku sečke potrebne za rad demo CHP postrojenja u preduzeću 'AGROSAVA' iz Šimanovaca

Abstract

U radu su prema proračunu proizvodnosti sečke koja je potrebna za gasifikaciju u demo CHP postrojenju radi kogeneracije električne i toplotne energije, analizirani iverači prema: vrsti mobilnosti, pogonu za iveranje i načinu dopremanja sečke do mesta iveranja. Postrojenjem je planirano dobijanje električne energije snage 200 kWe. U razmatranje su prvo uzeti iverači srednjeg kapaciteta koji uglavnom služe za iveranje granjevine i lišća koje ostaje nakon seče zasada po uglavnom ravničarskim predelima i parkovima. Kasnije su date uporedne karakteristike najveća tri svetska proizvođača mašina za proizvodnju sečke znatno većih količina (do 30 m3/h). Ovi iverači naročito su pogodni za veću gustinu zasada i stacionirane baze na koje bi se granjevina donosila i iverala. Na kraju su analizirani tipovi konvektivnih sušara koje bi se uspešno koristile za sušenje sečke (dobošaste i pneumatske sušare) i na osnovu proračuna predloženi su tipovi sušara koje se mogu nabaviti na domaćem tržištu.

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.
