BAGASSE FIRED BOILER

 

Introduction

HWEL is manufacturing Bagasse cum Oil or Gas Fired Boilers since inception. HWEL
during this period, have designed, manufactured and installed these Boilers for several
Industrial installations, mostly Sugar Mills and Distilleries. HWEL has gained expertise
in supply of Boilers of any capacity upto 100 tons/hr and any pressure upto 50 bar.
Most of the Boilers are tailor made to customer's requirement and of state of the art
design. Engineers in our Boiler division have been trained abroad in Design and
Quality Assurance.

Specifications

• Capacity Any capacity upto 100 tons
• Fuel Bagasse, Furnace Oil, Gas in any combination.

• Dust Catcher.
• Fans.
• Casings, Ducts and Chimney.
• Platforms, ladders and supporting structure.
• Instrumentation and Controls.

Manufacturing and Quality Control Facilities

Our manufacturing facilities are one of the largest in the country and occupy area of
______M2. The biggest bay is 21 M wide and has cranes from 10 to 30 tons capacity.
The special facilities for boiler manufacturing include:

Template cutting machines.
Plate Rolling machines capable of rolling plates upto 70 mm thickness.
Argon welding machine.
Heating Furnace and Hydraulic Press for dished heads forming.
TIG welding machine.
Bevelling and paralle flame cutting machines.
Large drilling machines for drilling of Boiler Drums.
Sand blasting facilities
Stress Relieving Furnace to accommodate 2 M dia amd 10M long drums.
Modern Push Bending Machine for tube bending.
X-Ray equipment.

Hydraulic Test Units.

Quality Control:

Design and manufacturing of Boiler Equipment is carried out as per ASME Code. HWEL follows strict quality asurance measures and Quality Control for inspection of Boiler equipments. We are a Company Certified under ISO-9001-2000. Inspection of products is done by any of the World Known Agencies such as Loyds. SGS, American Breauro of Shipping or TUV.

Instrumentation and Controls:

HWEL Boilers are equipped with automatic starting and tripping equipment. Entire Boiler can be started from a single push button according to a sequenced program. Failure of any important parameter would lead to automatic tripping of fuel supply to Boiler Burners. Control of Boiler through instruments and automation not only improves efficiency but also reduces operational manpower.

Automatic Protection includes:

• High and low water level protection with audio and visial alarm.
• Full flow stoppage upon flame failure.
• Steam cut off upon high pressure.
• Gas low and high-pressure protection.
• Gas leak off protection.
• Metering and record.
  
  
  HWEL Also Provides:
• Most modern bagasse conveying, feeding and spreading equipment.
• De-aerators and feed warter tanks of different types and sizes as per
• Customer's requirement.
• Water treatment units.
• Installation and commissioning services.
• Boiler modifications and improvements.
