Combustion Engineering

BMA provides pre-engineering and detailed engineering for the supply and installation of combustion equipment or accessories. Whether the equipment is designed and customized by BMA or purchased "off-the-shelf", BMA will use its knowledge and expertise of the different combustion equipment technologies to carry out the engineering necessary to ensure that the equipment will meet all your present and future needs.

Pre-engineering will take the guesswork out of budgeting for your project.  Subsequent detailed engineering can include:

• Specifications for new equipment, such as boilers, furnaces, dryers, or heat exchangers, or accessories such as burners, fuel trains, or other boiler or furnace auxiliaries, while adhering to applicable codes such as CGA (Canadian Gas Association), NFPA (National Fire Protection Association), etc.
• Preparation of a bidding package
• Bid analysis
• Assistance with obtaining installation approvals or certification
• Production of the necessary drawings (layout and general arrangements, P&ID, PFD, assembly and fabrication) and procedures
• Project management

A few examples of how clients have benefited from BMA's combustion engineering services:

Operating cost savings:

BMA provided engineering for modifications to the burner and other auxiliary equipment of a 150,000 lb/hr package boiler at a pulp and paper mill steam plant. The modifications increased turndown and thus prevented venting of excess steam during the summer months. Engineering included specification of new components, preparation of installation drawings, supervision of installation carried out by plant personnel, and start-up assistance. The improved turndown resulted in a project payback period of three months.

Improved operating flexibility:

BMA provided engineering for the modification of the burner and fuel train of four rotary kilns of a ferroalloy plant with capacities ranging from 150-180 MMBTU/hr in order to convert to dual fuel operation which would provide more operating flexibility. Engineering included preparation of technical specifications and drawings for burner and fuel train modifications, assistance for CGA approval and certification, supervision of installation carried out by plant personnel and start-up assistance for each kiln in series. The project allowed the plant to use natural gas to supplement its primary fuel (blast furnace top gas) to maintain a more even heat input to the kilns and thus, a better product quality.

Equipment upgrade:

BMA provided engineering for the modernization of the burner for a 25 MMBTU/hr coal dryer of a ferroalloy plant. The engineering included preparation of technical specifications, scope of work and performance specifications, preparation of a bidding package for the supply of the new burner and combustion air fan, design and production of fabrication drawings for a new windbox and pre-combustion chamber, selection and sizing of fuel train components, layout and installation drawings for the burner, fuel train and auxiliaries, installation supervision, and start-up assistance. In addition to modernizing the burner, which had become obsolete, the project also allowed the plant to convert to dual fuel operation (diesel oil and blast furnace top gas), with improved operating reliability and stability.
