Boilers works as steam generation units and
finds use in industrial applications especially in areas where steam is
required for process handling. The industry areas includes pulp, paper,
sugar plants, rice mills, chemical, food industries and others. The boilers
are based on factors such as exit pressure of steam, capacity of steam
generation, type of fuel, type of construction, type of feeding of fuel and
others.
Features :
- We can offer boilers under options like Single Drum or Bi-drum or
Multi Drum or Travelling Grate or Dumping Grate Boilers
- These can be supplied in steam production capacity from 5 MT to 175
MT as well as pressure from 10 Kg/cm2 to 110 Kg/cm2
- For firing of boilers, some of the fuels that are suitable include
Wood Chips, Paddy Husks, Bagasse (from cane), Groundnut Shell, Coal,
Lignite, Cocoa Shell, Saw Dust and others
Applications :
These are suitable for processes requiring steam including :
- Pulp industry
- Paper industry
- Sugar plants
- Rice mills
- Chemical industry
- Food industries
AFBC Boilers
AFBC Boilers are based on latest Atmospheric Fluidized Bed
Combustion (AFBC) technology and come with bubbling bed type configuration.
Backed by extensive R&D so as to ensure optimum utilization of existing
energy sources, we ensure the solutions offered by us are user-friendly as
well as suitable for firing varied low calorific value fuels.
Features :
- Comes supported by specially developed fuel feeders & feeding
system for handling even fuels with superior moisture content
- Comes with innovative protection feature for handling bed swept
surfaces
- Innovative oil-fired start-up system that does not require manual
intervention and provides for trouble-free unit start-up
- Allows for simple operation support
- Delivers optimum versatility in applications
- Can be made available in Bi-drum/Single Drum, Natural circulation
top/bottom supported or Water Tube design options
- Comes with better evaporator design for delivering better operation
reliability
- Made available with multi-fuel firing operation support
- Features under bed/over bed fuel feed system support
- Can also be offered with bottom hopper design for specific
applications
- Delivers optimized combustion support with staged secondary air
system
Applications :
- Highly suitable for saturated & super heater steam required
captive and cogeneration power plants
Bi-Drum Boilers
Bi-Drum Boilers find application in generating high
steam-pressure needed for cogeneration/ incidental power generation. These
are specially demanded in saturated steam applications demanding
uninterrupted operation on highly choking fuels. The quality construction of
these boilers also makes these deliver continuous operation support
throughout the year. Further, as these have small water content, these
rapidly respond to changes in heat inputs and loads.
Features :
- In these boilers, water is circulated inside tubes with surrounding
heat source
- Energy generated from heat source can be extracted as
radiant/convective & conduction form
- Features furnace/radiant section which functions as open area
accommodating flames
- Walls of furnace section coming lined with finned tubes known as
membrane panels that come designed for absorbing radiant heat from flame
- Two drums come connected through large number of convective heat
transfer tubes
- Can be delivered in over bed & under bed options
- Delivers better fluidization as well as more residence time
- Helps in achieving superior combustion efficiency
- Boilers available with larger capacities as well as high pressures
find usage for cogeneration of process steam & power using suitable
turbine support
Applications :
- These are used in generating high steam-pressure needed for
cogeneration/ incidental power generation.
Travelling Grate Boilers
Travelling Grate Boilers is operated through burning of
mustered husk and paddy straw and provides for superior combustion
efficiency. Providing for high operation reliability, these also ensure low
down time as well as comparatively less fouling and sagging possibilities.
Features :
- System designed to deliver continuous discharge of ash
- Can be made available with bi-drum/single drum options with natural
circulation support
- Features top supported design
- Features tall furnace for achieving staged/complete combustion
- Allows for optimized combustion using staged secondary air system
- Features 2 stage/3 stage super heater support with provision of
inter-stage spray attemperator
- Allows achieving even fuel distribution on entire grate
- Comes with modulating cyclo motor for spreader dampers
- Features presence of grate driven using mechanical/ hydraulic drive
Applications :
- Process & Power applications for generating high steam-pressure
Dumping Grate Boilers
Dumping Grate Boilers comprise generously sized great and come with soot blower support for achieving on load cleaning of heating surfaces. Coming with secondary air distribution system, these are pneumatically operated sectionalized dumping grate with two stage superheaters as well as single stage attemperator that allows in achieving accurate steam temperature control
Features :
- Process & Power applications for generating high steam-pressure
- Comes with generously sized grate
- Features grit re-firing system as well as soot blowers for achieving
optimum on load cleaning of heating surfaces
- Comes with secondary air distribution system with environment
friendly operations as well as electrostatic precipitator type pollution
control that limits particulate emission up to 30 mg/nm3
- Also features on-line bagasse storage silo for achieving stable
boiler operations
- Features single/three drum feeder option for bagasse feeding as well
as space tube/membrane panel furnace options
- Comes with pneumatically operated sectionalized dumping grate
Applications :
- Reduce radiation losses and uses maximum heat extracted from furnace
