Control System of Flying Reconnaissance Flying Robot fot Indoor Environment
Kříž, Vlastimil ; Burian, František (referee) ; Žalud, Luděk (advisor)
This work deals with multi-rotor helicopters, known as copters. The first part is a review of existing solutions, and an appropriate platform for use as aerial reconnaissance vehicle is chosen. In the next part a mathematical model of copter is created and its parameters are estimated. Based on this model a state-space controller for control system is designed. This is then tested on the created model and implemented in real copter.
Pyrolysis of coal/waste plastic mixtures in cokemaking
Melegy, A. ; Sýkorová, Ivana ; Kříž, Vlastimil ; Havelcová, Martina
In the recycling process of waste plastic using coke oven, sub-bituminous coal and added 5 vol. % of plastics are carbonized and changed into coke of optimal properties, tar and gas .
Application of a rotary kiln for the treatment of carbonaceous materials of the selective waste polymer and biomass type
Kříž, Vlastimil ; Bičáková, Olga ; Náhunková, Jana
In the rotary kiln, samples of polypropylene and sawdust in model mixtures with bituminous-coal coke at a temperature of 900°C were pyrolyzed. The composition and features of the pyrolytic gas and solid product were observed.
The use of mixed waste polymers in thermal treatment with brown coal
Kříž, Vlastimil ; Bičáková, Olga ; Machač, P.
Samples of brown coal from Jiří Mine alone and its mixtures with waste plastics were gasified on a laboratory scale. Using a thermal-degratation module, inserted in the stream of volatile products of pyrolysis and gasification, energetic gas with with higher hydrogen content was obtained.
Kontinuální pyrolýza uhlíkatých materiálů s modelovým zplyněním tuhého produktu
Kříž, Vlastimil ; Káš, Václav ; Brožová, Zuzana
Samples of lignite from Jiří Mine alone and its mixtures (30%) with waste tire-rubber, Forsan (ABS) and cellulose were pyrolyzed on a rotary kiln at a temperature of 900°C. The solid product was gasified by steam and carbon dioxide.
Vodík - produkt tepelné konverze uhlí
Kříž, Vlastimil ; Brožová, Zuzana
Hydrogen fixed in the coal structure was converted to gaseous form using two-stage pyrolysis. The hydrogen volume in the pyrolytical gas strong increased along with the temperature in the cracking module. There was verified the possibility to obtain hydrogen by thermal decomposition of coal pyrolysis volatile products.
Treatment of waste rubber by co-gasification with brown coal
Straka, Pavel ; Kříž, Vlastimil ; Káš, Václav ; Hanzlíček, Tomáš ; Brožová, Zuzana
Experiment in industrial scale proved that waste rubber can be treated by co-gasification with brown coal.
Experimental verification of possibility of waste plastics gasification with brown coal
Straka, Pavel ; Káš, Václav ; Kříž, Vlastimil ; Brožová, Zuzana
Process conditions research proved that waste plastic and municipal waste with plastics can be treated by co-gasification with brown coal.
Alternativní využití organických odpadů - jejich ko-procesing s uhlím
Kříž, Vlastimil ; Bučko, Z.
Samples of brown coal mixed with real organic wastes were gasified in a laboratory model gasification unit, using steam and carbon dioxide for gasification. The co-gasification possibility of brown coal/waste tires mixtures at industrial scale was verified.
Laboratory model unit for gasification of carbonaceous materials at atmospheric pressure
Kříž, Vlastimil
A laboratory unit for sample gasification up to 40 g of weight with continuous selected gas components analysis is described.
