Changing consumer choice to ethanol can
1. Reduce dependency on foreign oil
2. Reduce pollution and clean the atmosphere
3. Slow climate change
4. Provide a more renewable fuel source
The use of ethanol blends in conventional gasoline vehicles is restricted to low mixtures up to E10, as ethanol is corrosive and can degrade some of the materials in the engine and fuel system. Also, the engine has to be adjusted for a higher compression ratio as compared to a pure gasoline engine to take advantage of ethanol's higher oxygen content

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

2. INTRODUCTION
• Alternative fuels, known as non-conventional or advanced
fuels, are any materials or substances that can be used as
fuels.
• Conventional fuels include: fossil fuels (petroleum (oil), coal,
and natural gas).
• Alternative fuels include biodiesel, bioalcohol (methanol,
ethanol, butanol), chemically stored electricity (batteries and
fuel cells), hydrogen, non-fossil methane, non-fossil natural
gas, vegetable oil, propane, and other biomass sources.

4. ETHANOL FUMIGATION
• Ethanol fuel is ethanol (ethyl alcohol C2H5OH ), It is most
often used as a motor fuel, mainly as a biofuel additive for
gasoline.
• Creation of ethanol starts with photosynthesis causing a
feedstock, such as sugar cane or a grain such as maize
(corn), to grow. These feedstocks are processed into ethanol.
• Ethanol fumigation is method to spraying gaseous ethanol
into the incoming air or fuel-air mixture.
5. ADVENTAGES
• Increase brake power and torque.
• Volumetric efficiency increased.
• Brake specific fuel consumption decreased(BSFC)
• Reduce CO,HC and NOx emission.
6. LPG
• Liquefied petroleum gas or liquid petroleum gas (LPG or LP
gas), also referred to as simply propane or butane, are
flammable mixtures of hydrocarbon gases used as fuel in
heating appliances, cooking equipment, and vehicles.
• LPG is used to fuel internal combustion engines, it is often
referred to as autogas or auto propane
7. ADVENTAGES
• High Octane Number and Low Evaporation residue of Auto
LPG ensures high efficiency
• Low volumes of vehicular exhausts like CO, SOx, NOx,
Benzene and Particulates etc.
• Auto LPG eco - friendly, resulting in improving the general air
quality.
8. OBJECTIVE
• To built the dual fuel fumigation engine (Ethanol & LPG)
• To condect performance test.(Fuel consumption Torque,
BSFC & BMEP)
• To find the emission characteristics (HC,CO,NOx) of engine
with varies engine speed at varies fumigation rates.
• To compare the results.
9. COMPONENTS TO BE USED
• Ethanol tank
• Petrol tank
• LPG tank
• Two stroke petrol engine
• Evaporator kit
• Stand
11. Engine Specification
• Model= TVS XL Super
• Type = 2 stroke single cylinder petrol engine
• Displacement = 69.9cc
• BrakePower = 2.61 Kw ( 3.5 BHP) @ 5000 rpm
• Max Torque = 50 N-m @ 3750 rpm
• Bore (D) = 46 mm
• Cross section area of cylinder ( A ) = 1661.06 mm2 = 0.0017 m2
• Stroke (L) = 42 mm = 0.042 m
12. Evaporator kit
• LPG vaporizer and solenoid valves are important components in the
LPG Conversion Kits. It is important to store LPG which contains
propane and butane mixture in pressurized containers in liquid
state. This liquid must undergo a phase change into gas so that the
empty space above the liquid in the container is filled by vapour
which is used as fuel. Thus LPG enters as a liquid and exits as a
gas.
13. WORKING PRINCIPLE ETHONAL FUMIGATION
• The fuel and air is supplied from the carburetor already
used in petrol engine.
• Evaporator kit is used to vaporized LPG and Ethanol.
• Vaporized LPG or Ethanol is feed into the carburator.
• Air/petrol mixure with Ethonal or LPG is drown into the
engine during the intake stroke.
• Performance and Emission test are carried out with
testing setup.
14. Two Stroke Engine
• A two-stroke engine is a type of internal combustion
engine which completes a power cycle in only one
crankshaft revolution and with two strokes of the piston.
• This is accomplished by the end of the combustion
stroke and the beginning of the compression stroke
happening simultaneously and performing the intake and
exhaust (or scavenging) functions at the same time.
• Two-stroke engines often provide high power-to-weight
ratio.
15. Two Stroke Engine Intake
• The fuel/air mixture is first drawn into the crankcase by the vacuum
that is created during the upward stroke of the piston. The illustrated
engine features a poppet intake valve; however, many engines use
a rotary value incorporated into the crankshaft.
16. Two Stroke Engine Transfer/Exhaust
• Toward the end of the stroke, the piston exposes the intake port,
allowing the compressed fuel/air mixture in the crankcase to escape
around the piston into the main cylinder. This expels the exhaust
gasses out the exhaust port, usually located on the opposite side of
the cylinder. Unfortunately, some of the fresh fuel mixture is usually
expelled as well.
17. Two Stroke Engine Compression
• The piston then rises, driven by flywheel momentum, and
compresses the fuel mixture. (At the same time, another intake
stroke is happening beneath the piston).
18. Two Stroke Engine Power
• At the top of the stroke, the spark plug ignites the fuel mixture. The
burning fuel expands, driving the piston downward, to complete the
cycle. (At the same time, another crankcase compression stroke is
happening beneath the piston.)
21. Two Stroke Engine Port Timing Diagram
• Intake port opens 35° to 50° prior to TDC position which closes
same amount after TDC place.
• Exhaust port opens and closes 35° near 70° before and after BDC
place, in that order.
• Transfer port opens 35° to 60° in the proceed to BDC closes 35° to
60° after TDC place.
• Ignition takes place with spark by 15° to 20° before TDC place as
charge requires for a while to ignite.
• The exhaust and transfer ports open and close at the same angles
on also side of BDC.
22. Performance Test
• Fuel Consumption ( mf) = ( Volume of fuel consumed in m3 x
density of fuel ) / Time (Kg/sec)
• Torque = ( Brake power in Kw x 60000) / ( 2Л x engine rpm) N-m
• BSFC = ( mf x 3600) / Brake power in Kw kg/Kw.hr
• BMEP = ( Brake power in Kw x60000) / ( L x A xengine rpm)
N/m2
23. Calculation
1)Fuel Consumption ( mf) = ( Volume of fuel consumed in m3 x
density of fuel ) / Time (Kg/sec)
Fuel Consumption ( mf) = (0.00005 x 719.7)/20.1
Fuel Consumption ( mf) = 0.00017903 kg/sec
Fuel Consumption ( mf) = 0.64 kg/hr
2) Torque = ( Brake power in Kw x 60000) / ( 2Л x engine rpm) N-m
Torque = ( 2.6x 60000) / ( 2Л x 1000) N-m
Torque = 24.84 N-m
24. Calculation
3) BSFC = ( mf x 3600) / Brake power in Kw kg/Kw.hr
BSFC = ( 0.00017903x 3600) / 2.6 kg/Kw.hr
BSFC =0.25 kg/Kw.hr
4) BMEP = ( Brake power in Kw x60000) / ( L x A x engine rpm)
N/m2
BMEP = ( 2.6 x60000) / ( 0.042 x 0.0017 x1000) N/m2
BMEP = 21.85 N/m2
47. CONCLUSION
• The results of tests conducted in a LPG and ethanol fumigated two
stroke petrol engine at eight different engine speed, without engine
load to ascertain the influence of LPG/ethanol fumigation on
specific fuel consumption, engine power, torque, BSFC, BMEP
,HC,CO and Nox can be concluded as follows.
• While fumigating LPG/Ethanol to the petrol engine the resulted in
a reducing in specific fuel consumption and BSFC .Also fumigation
increase the BMEP and engine torque. The HC, CO and NOx
levels for fumigation run were less than that for neat petrol run.
48. CONCLUSION
• We compare results with petrol , petrol LPG fumigation and petrol
ethanol fumigation finally concluded that LPG fumigation is give
better performance and emission characteristic, compare with
ethanol fumigation due to there higher calorific value and octane
number.
