Bu çalışmada, yüksek oranlarda kül içeren ülkemiz
linyitlerinin sabit yataklardan daha hızlı bir şekilde yakılması amacı
ile, 40 kW lık döner yanma odalı bir yakma sistemi tasarlanmış ve
prototip üretimi yapılmıştır. Sistemde, kömür bir sonsuz vida
tarafından bunkerden sabit devirde kendi ekseni etrafında sürekli
olarak döndürülen silindirik yanma odasının arkasına sürekli olarak
taşınmaktadır. Hava eski sistemlerden farklı olarak, kömür yatağına
başlık ekseninden radyal doğrultuda sağlanmıştır.
Sistemin performansının ortaya konulması amacıyla Tunçbilek
linyitinin yakılmasında, baca gazı bileşimine linyit ve hava besleme
hızlarının ve ayrıca yanma verimine yanma odası eğimi ve dönme
hızının da etkisi araştırılmıştır.
Deneysel sonuçlar, Tunçbilek linyitinin böyle bir sistemde oldukça
hızlı, verimli, pratik ve düşük atmosferik kirletici emisyon düzeyleri
ile yakılabileceğini göstermiştir.
In this work, a 40 kW coal combustion system with
a rotary chamber, to burn our country’s lignites, which usually
contain high level of ash, faster than fixed beds was designed and a
prototype model was constructed. In the system, coal has been
continuously carried by a screw conveyor from an hopper to the
cylindrical burner head rotating continuously at a constant speed. As
a difference among the previous systems, combustion air was
supplied, by an axially-centred air tube carrying screw conveyor, into
the air head in radial directions to the coal bed.
In order to evaluate the performance of the system, the effects
of feed rates of lignite and combustion air, angle of tilt and rotation
speed of the burner head on the flue gas compositions and
combustion efficiency were investigated.
The results of the experiments showed that Tunçbilek lignite
could be burned with this kind of system in fast, efficient and
practical and acceptable atmospheric pollutants levels.

Fuel injection system is one of the most important
equipment which affect the engine performance in internal
combustion engine. In available systems fuel is sended
pressurized to combustion chamber, behind intake valve or
intake manifold throat and fuel-air mixed is created. The most
important advantages of injection systems are increase the
combustion efficiency by atomizing the fuel. The atomization of
the fuel is provided by high pressure.
In this study, the effects of using ultrasonic atomization method
as a new atomization method in internal combustion engines
were investigated on the vehicle performance under road
conditions. Therefore, an ultrasonic fuel injection system was
designed and a four-stroke, four-cylinder, spark ignition
carbureted motor was installed. The road simulation was
determined on the vehicle chassis dynamometer and the fuel
consumption and exhaust emission values were obtained by
operating the vehicle for a certain period in urban conditions for
a certain period under intercity conditions. Existing conditions
have been repeated in the performance of the engine with the
original fuel system. The results are converted into graphics and
interpreted.
As a result, it has been observed that there is a significant
reduction in fuel consumption and exhaust emission values
