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

• 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
Steam turbine generators are 3-phase, WYE-connected, 50Hz, and totally CACW (closed air closed water) synchronous machines rated at the capacity suited for operation at the maximum capability of corresponding steam turbines.

Auxiliaries related to turbo-generator:
