Conforma Clad Burner Components

...lengthen run-times and reduce maintenance costs by up to three times!

1. Increased Productivity

Extended burner component life results in fewer equipment shutdowns and component changes, lengthening run-times between maintenance windows.

2. Enhanced Burner Performance

Decreased burner component wear leads to better NOx performance, leaving you with more credits for sale.

3. Superior Erosion Resistance

One sixteenth inch (1.5 mm) of Conforma Clad’s wear protection performs fifteen times better against erosive wear than an equivalent layer of typical overlays and fifty times better than plain carbon steel. And it is up to twenty-five times more erosion resistant than high-temperature stainless steels.

4. Proven Results

Conforma Clad’s premium technology has been used in coal-fired power plants for more than 15 years, extending the life of burners, gas fans, boiler tubes thermowells, ash conveyance equipment, pitot tubes, pulverizer components and other plant equipment.

Conforma Clad is a leading provider of severe wear solutions for applications involving extreme abrasion, corrosion, impact and erosion. Our proprietary infiltration brazed tungsten carbide
cladding is metallurgically bonded to burner components. Conforma Clad’s cloth delivery system enables densely-packed tungsten carbide to be uniformly applied to complex geometries, providing a protective barrier that wears at a uniform and predictable rate.

Conforma Clad® burner components last longer and sustain maximum performance levels by maintaining critical component geometries for extended run times. The proven reliability of Conforma Clad® components has made us an industry standard.

Erosion Resistance

Riley Power conducted laboratory testing, following ASTM G73 standards, on low swirl coal spreaders to determine the best erosion protection from fine-grit black beauty coal slag. Testing was conducted at a 90° impingement angle with a particle velocity of 240 ft/sec for 30 minutes.

Conforma Clad’s WC 219 cladding provided top wear protection while retaining critical component geometries. Conforma Clad increased Riley Power’s low swirl coal spreader life from 1-2 years to 3-4 years.

Performance Data

Conforma Clad protects low NOx burner components at coal-fired power plants throughout the country, including Wisconsin Electric, Valley Station’s CCV® burner spreaders. Coal spreaders are essential components in distributing pulverized coal to the burner flame and are designed to enhance combustion by controlling the flame length and minimizing NOx and Unburned Carbon (UBC). In order to maintain critical geometries and coal distribution patterns, the coal spreader vanes are protected with Conforma Clad’s tungsten carbide cladding.

The Valley Stationplant’s burner components experience increased erosion rates because of high burner velocities (approximately 87 ft/sec) and the coal’s high silica and alumina content.

Wisconsin Electric tripled the service life of their Riloy® 74 (50Cr/50Ni with Cb) spreaders by applying 0.040" of Conforma Clad® tungsten carbide cladding to the spreader’s leading edges.

Low Swirl Coal Spreader Wisconsin Electric tripled the service life of their Controlled Combustion Venturi® burner components with Conforma Clad.
