US Maintenance Services for Coal and Biomass Burning Boilers
With decades of experience providing mechanical and refractory services in pulverized coal, CFB, and grate fired boilers in the US power industry, IGS had the knowledge to develop and implement the best boiler maintenance services for each individual client.
We understand the difference between providing technical expertise for long term solutions improving boiler capacity and efficiency and offering lesser repairs. We operate in strict compliance with ASME Section VIII and IX, our stringent Quality Control plan, and customer specific requirements. We provide welding per our MIG, TIG, GMAW, and SMAW weld procedures. Our field service teams are non-union, which provides a more self-sufficiency which leads to a more efficient and lower cost model for our customers. Our maintenance services include metal spray coatings for life extension of the boiler, in addition to mechanical and refractory services.
IGS understands the dynamics of working in an outage, where every minute saved means less costs to the owner and have developed both our US based and our global infrastructure to meet all of our clients’ needs.
We Are Maintenance and Refractory Services Specialists
The power industry in the United States has undergone a dramatic change, with many plant closings putting more operational pressure on the remaining coal and biomass burning boilers. Outage cycles have been extended in order to reduce annual maintenance costs and maximize revenue. Premature boiler failures causing forced outages must be avoided in order to ensure maximum capacity and availability.
In terms of mechanical services in CFB boilers, IGS has successfully performed many replacements of vortex finders, including the refractory services. We supply and install the vortex finder during critical outage time due to the knowledge and expertise of our project managers and technicians. We have also developed and installed a new block nozzle design in lieu of the existing arrowhead design for longer life due to reduced plugage. IGS also supplies a number of other services in CFB units such panel replacement, welding and grinding, loop seal replacement, and tube shield work.
In PC-fired units, IGS has superior expertise in the backend of power plants in SDA chambers and SCR units. We have the capability to make metal repairs to the SDA chambers, and apply our metalspray coatings to extend the life of the carbon steel. We have successfully performed these services for many utilities, including Basin Electric Antelope Valley Station and for Edgecombe Genco.
In terms of the SCR, IGS has services for improved performance and extended catalyst life. IGS can supply and install specially designed LPA screens upstream from the catalyst to protect against Large Particle Ash, and secondary screens over the catalyst for additional protection. IGS also provides expertise in removing catalyst layers and installing new layers in the SCR. We have performed numerous catalyst installation projects within the critical path outage schedule and within budget
