6. Biomass Energy
 Biomass energy means producing energy does not
have to threaten the environment.
 Biomass power plants combust waste to produce
electricity.
 waste means Agriculture waste, Forest waste, Sugar
industries waste like etc…..

7.  Biomass fuels include wood
waste such as:
 Urban wood waste like
construction wood scraps,
broken pallets, clean wood
waste from factories and
residue from tree trimmers
 Forest waste like small trees
and undergrowth cleared
from forests for fire
suppression and growth
enhancement
 Agricultural waste like
orchard removals, rice
hulls, fruit
 Waste from sugar
industries like Bagass.
Types of Biomass

8. Biomass power plant overview

9. INTRODUCTION
 It works in Rankine cycle.
 Steam produced in Boiler is expanded in the prime
mover.
 Condensed steam is fed back to the boiler again.
 The steam turbine drives the alternator produces
electricity.
 Steam power plants contribute about 65% of total
electrical energy generated in India.

11. Rankine Cycle

12. Rankine cycle Procedure
 Process 1-2: Water from the condenser at low pressure
is pumped into the boiler at high pressure. This
process is called reversible adiabatic.
 Process 2-3: Water is converted into steam at constant
pressure by the addition of heat in the boiler.
 Process 3-4: Reversible adiabatic expansion of steam in
the steam turbine.
 Process 4-1: Constant pressure heat rejection in the
condenser to convert condensate into water.

14. Main systems in power plant
 Fuel & Ash Handling system
 Steam Generating system
 Steam Turbine
 Alternator
 Feed water
 Cooling arrangement system

15. Fuel and Ash handling plant
 Fuel is transported to power station
by road and stored in fuel storage
plant.
 Here Fuel means Bagasse, Husk ,
wood chips and pulverized coal.
 Fuel is fed to the boiler by belt
conveyers.
 Fuel gets burned in the boiler and
ash produced and it is removed to the
ash handling plant.

16. ASH HANDLING PLANT
The Ash from the boiler is collected in two forms.
1) Bottom Ash (Slurry):- It’s a waste which is dumped into a Ash pond.
2) Fly Ash:- Fly ash is separated from flue gases in MDC (Mechanical
Dust Collector).

17. Steam Generating system
Steam Generating system consists of a boiler for the
production of steam and other auxiliary equipment for the
utilization of flue gases.
1. Boiler
2. Economizer
3. Super heater

19. 1.Boiler:-
The heat of combustion in the
boiler is utilized to convert
water into steam at high
temperature and pressure.

BOILER

20. 2. Economiser:- Its
essentially a feed
water heater and
derives heat from
the flue gases.
3. Super heater:- The steam produced in boiler is wet
and is passed through the super heater where it is dried
and super heated. Increases efficiency also.

21. Steam Turbine
 Dry and superheated steam from super heater is fed to the Steam Turbine.
 The heat energy of steam when passing over the blades of turbine is converted into
mechanical energy through rotating the turbine rotor.
 After giving energy to the turbine, the steam is exhausted to the condenser which
condenses the exhausted steam by means of cold water circulation.
Steam Turbine with Alternator

22. Alternator
 Steam turbine is coupled to an alternator which
converts the mechanical energy to electrical energy due to
Faraday's law of Induction.
 The electrical output of the alternator is delivered to the
bus bars through the transformer, circuit breakers and
isolators.

23. Feed Water
 The condensate from
the condenser is used as
Feed Water to the boiler.
 The feed water on its
way to boiler gets heated
up by water heaters and
economizer.
 This helps to improve
the overall efficiency of
the plant.

24. Water Utilization
Water in a power plant is used for
 Production of steam – for rotating turbine.
 Cooling purpose – for cooling of various equipments.
3% of water is wasted during this process. Approx 4 cubic meter water is
lost/day/MW.

25. Cooling Arrangement
Cooling Tower • Condenser condenses the
steam exhausted from the
turbine.
• Exhaust steam cooling
purpose we are using a
cooling tower
•This hot water can be
discharged away or used
again by using a cooling
tower.
