HRSG & FBC boilers
Features & Characteristics:

• state-of-art design, research, development and manufacturing capability
• Granted ASME 'S' & 'U' stamps
•  Familiarity with IBR (Indian Boiler Regulations) of the statutory authorities

Vertical Type HRSG

Design basis & concept:

• Natural circulation HRSG
• Radiant cooling furnace, flue gas pass with super-heater and evaporator are designed as water cooled tubes of membrane construction acting as fully gas tight casing
• Convective third pass holding economizer section
• Fully drainable pressure parts with bare tube construction
• Single drum all welded construction
• Integral deaerator
• Cold casing insulation

Design features:

• Meet variation in flue gas volume and temperature, prolong service time of super-heater
• With lower and optimum flue gas velocity to reduce pressure part erosion problems
• Easy maintenance and accessibility
• Compact layout and limited land occupation
• Less erection workload and period

Horizontal type HRSG:

Design basis & concept:

• Natural circulation HRSG
• Radiant first pass without any tube bundles but with water cooled tubes of membrane construction
• Loose tube between first pass and second pass
• Convective second pass with bare tube evaporator and superheater
• Convective third pass with economizer
• Single drum all welded construction
• Integral deaerator
• Cold casing insulation

Design features:

• Large vertical fast passes meet variations in flue gas volume and temperature; prolong service time of superheater; facilitate delayed combustion of unburned CO that may originate during the upset condition; cool the waste gas well below abrasive temperature to reduce pressure part abrasion problems
• Lower and optimized flue gas velocity reduce pressure part erosion problems
• Bare tube construction avoids slag deposition / dust accumulation on heat exchanger surface and allows dust to fall freely into the hopper

Fluidized Bed Combustion Boiler

Design basis & concept:

• Capability to deal with rapid load changes, short start-up times
• High reliability and availability with low maintenance down time
• High combustion and boiler efficiency
• Excellent exhaust gas quality without flue gas desulphurization
• Wide turn down ratio and excellent load following capability
• Use of various fuels like rice hush and coal etc.

Auxiliaries related to boiler:

• Boiler feed water system including feed water pump, control valves and pipings etc.
• HP & LP dosing system
• Drauglit system including F.D. fan, I.D. fan and primary air fan etc.
• Deaerator
• ESP

Steam Turbine
Awarded the National Quality Medal, our steam turbine suppliers manufacture steam turbine of various types with power output up to 60MW for small and middle sized power station, covering condensing, back pressure, extraction, mixed pressure and machinery driving etc.

Characteristic of extraction condensing steam turbine:

• Suitable for various working conditions and speeds
• Automatic adjustment of power loading
• Under extraction or pure condensation operating condition
• EDH or fully hydraulic governing system
• Compact construction
• Easy and convenient installation
• Stable and reliable service
• Suitable to drive a generator or other machinery

Generator
