TSSA BASED SERVICES OFFERED BY ARCTIC COMBUSTION

Customers often have a need to determine whether they are in compliance with current TSSA (and other) code requirements. At Arctic Combustion, our service goes beyond inspecting the equipment for compliance, we provide a detailed analysis of your current code status and what is required to meet an approved state. This includes giving funding quality estimates as a way to quantify the costs to bring equipment up to this approved status.

Reviews of Burners, Boilers and other appliances 1

Including all Fuel handling equipment to the relevant TSSA implemented codes, generally B149.1, B149.3, B139.1 and B139.3. Other studies available provide life expectancy of the equipment involved life cycle costing, and approval impact estimates for control changes.


Recently our TSSA reviews and upgrades have often been on equipment upgrades involving:

  • Linkageless Controls Upgrades,

  • Cross-Limited Controls Upgrades,

  • Duct burner rebuilds and repairs for HRSGs

  • New Burner Installations for Lower Emissions

  • Approvals overlooked at installation

  • U.S. and other imported equipment

  • New and Used Boiler Installations

  • Rental Boiler installations

  • Service Contracts offered by Arctic Combustion

  • Process and heating related fuel handling systems (e.g. dryers, air heaters, and furnaces)


Audits of Existing Equipment with Fixed Price or Time & Material based reviews

Typically when performing an Audit, the deliverables are a list of items out of compliance, and a funding estimate as to the most cost effective, and most timely methods to bring the appliance up to code and receive an approval.

Arctic Combustion will perform a review of appliances etc. to current codes as well as identify developmental issues within the regulatory agencies involved that may be implemented within the affected time frames relevant to the equipment owner.

This will show and report equipment grandfathered2, equipment necessary to be upgraded, replaced, or re-designed for current compliance, as well as future compliance issues to be implemented within the life of the equipment. Additionally, determine when a pre-approved piece of equipment has broken its approval envelope and lastly, determine what is maintenance versus an upgrade3.


Critical Equipment and Information Reviewed

  • Burner Management Logic Devices and shutdown systems including reviews of PLC and DCS programming, panel wiring and relay design. Electrical approval and proper adherence to the electrical code is mandatory at this level.


  • Flame Monitoring for proper flame detection, and multi burner discrimination.


  • Firing and Appliance Controls; including adherence to new Linkageless controls (FARC) requirements being implemented by TSSA. This includes reviews of PLC and DCS programming, panel wiring and where necessary, Failure Mode and Effects Analysis.


  • Fuel Trains for delivering, and controlling fuels such as natural gas, oil, plus extensive experience with process fuels, waste fuels, liquid and gaseous. Attention is given to piping design, procedures, code compliance such as B31.1, flanges, and component selection as to current and past CSA standards and labeling for general approval, with appropriate flow and pressure sizing.


  • Fuel Venting System design for proper sizing to provide functional and compliant pressure relief, paying particular attention to cost-to install wall penetrations, roof penetrations, and general piping runs.


  • Fresh Air and Combustion Supply Venting design for proper sizing to support the appliance/boiler and where necessary augment the mechanical supply with auxiliary instrumentation


  • Chimneys, Breeching and Multi-Flue Stack design, (using our unique relationship with Industrial Chimney Maintenance) for reviewing the quality and appropriateness of the exhaust system design and stack condition. We include this as a matter of course in all large system reviews.


Who does the Audits and Field Approval Submissions?

For minor projects, Arctic Combustion uses a technician (6 available) with the appropriate gas or oil certifications to perform the on-site work and relatively straightforward approvals. Larger scopes usually entail a professional engineer or designer from Arctic Combustion with considerable experience for large scale, involved submissions, including variances submission and logic system design (PLC or DCS), as well as a professional engineers stamp for one-of-a-kind situations.


What if I am out-of-compliance and I cannot do the upgrades quickly?

Arctic Combustion regularly seeks and obtains variances to continue operation based on developing a plan and schedule to upgrade the equipment at a later date, where TSSA inspectors and later, our technicians test and validate the safe operation of the current installation until the necessary changes are made.


Pressure Vessel and Piping registrations

Arctic Combustion maintains a TSSA approved Quality System for Boiler repairs and Alterations, Power Piping and Process Piping. All of these Systems reference ASME B31.1 and B31.3. In addition to these approved programs Arctic Combustion has worked with customers to get their programs approved. We offer a full range of support, including:

  • Arctic Combustion performing all work at a customers site

  • Providing approved work using Arctic Combustion programs and procedures for selected work on a customers site, applying for new “P” numbers, or even CRNs where appropriate

  • Providing welders that can work to a customers program and procedures

  • Supplying support for a customer to obtain an Approved program

  • General liaison with TSSA on the customer’s behalf for unique applications and systems.


At Arctic Combustion we are in regular discussions with the Ontario Technical Standards and Safety Authority and their Provincial counterparts across Canada on all matters related to Fuels, Boilers, Pressure Vessels and Operating Engineer regulations. We may be able to give you guidance directly, or we can assist you in formulating enquiries that you may have to the appropriate division or individual within the TSSA. The requirements for Canadian Registration, the acceptable Quality Programs and the Certificates of Authorization required to import equipment into in Canada can be a problem for non Canadian Companies as these requirements apply over and above the ASME Boiler and Pressure Vessel Code requirements. As well, Operating Engineer regulations and their associated equipment horsepower differ across North America.

Allow us to bring our considerable experience and expertise to assist you with our extensive experience of the applicable Canadian and Ontario Acts and Regulations.

Notations:

1 An Appliance is any fuel burning equipment covered under the authority having jurisdiction; in Ontario’s case, the Technical Standards and Safety Authority (TSSA).

2 According to information presented by TSSA personnel, appliances are considered to be modified and shall be re-approved when:

  • Fuel input changes in excess of plus or minus 20%

  • New installations of relocated/moved equipment

  • Gas supply pressure changes in excess of 10%*

  • Fuel is changed or new fuel is added to existing approved appliance

  • Process temperature is increased to above existing high temperature limit setting.

  • Sequence of operation or logic are modified

3 Maintenance versus Upgrade

Rationale: Allows for equipment to be upgraded without upgrading entire system. This promotes an increase in safety rather than deterring it by the economics of upgrading the entire system.

Premise: The equipment was approved at the time of installation. Equipment that was not installed and approved in accordance with the codes/regulations at the time of installation cannot be grandfathered.
