RPM has used laser cladding technology to repair a wide variety of shafts since 2004. From out-of-tolerance ash crusher shafts to galled drag line swing shafts, laser cladding has proven itself to be the most timely and reliable solution to shaft wear problems. Unlike spray repair, laser cladding provides a metallurgical bond that wont lift or spall under tough operating conditions. Our engineers will choose the best alloy for your specific wear environment.

Some shaft repairs that have been completed by RPM & Associates include Trunion Shafts, Coal Pulverizer Journal Shafts, PA Fan Shafts, Atomizer Shafts used in Flue Gas Desulfurization Systems, and Pump Shafts. Following are a number of specific case studies of shaft repairs RPM & Associates has completed.

A high-speed 4340 drive shaft was repaired using a conventional spray process. Note the severe spalling in the repaired tapered area of the shaft. The user tolerated this recurring problem due to lack of other options for repair. The LCT process was introduced to the customer and now several of these shafts have been successfully repaired using 420 stainless.

An HP 1103 Journal Shaft from a coal pulverizer system was brought into our shop for repair. The shaft was worn on three surfaces and one face. RPM & Associates has since repaired a number of these shafts.

RPM & Associates performed a repair of a spindle sleeve for a horizontal boring mill using Laser Cladding Technology (LCT). The cladding for this part, due to its size, was performed in open atomosphere. Distortion was kept to a minimum by running the laser at 465 watts and using a 1 mm spot size. 420 LC SS powder was used to give the part better wear resistance.

This example Trunion Shaft had two sections that had worn out. The shaft was machined to minimum cleanup. A process was developed to deposit 420 SS (stainless steel) to build up both surfaces of the Trunion Shaft. The 420 SS material improved the wear resistance of the part to future wear. After material was built up, the Trunion Shaft was then machined to its final dimensions.

The following repair was done on a 4340 Swing Shaft used on a drag line in a coal mine. The 4340 Swing Shaft is 16 1/2 ft. long and weighs 25,000 pounds. Conventional repairs on this type of shaft were not possible due to high heat input.

The repair cost is approximatley 65% less than new and extends the operational life of the shaft compared to new due to the materials used. A number of these shafts ranging in various sizes have been repaired.

A 1035 PA Fan Shaft was knocked out of tolerance due to a crash that occurred while in service. The shaft is a precision shaft that runs at 1,725 RPM and 3,500 horsepower in an ambient condition. Diametrical tolerances are within 0.0005" and run out tolerances are also within 0.0005".

While overhauling a CE11003 journal, we found the shaft had a prior spray on bronze repair at bearing fit location that was failing. Bronze debris was contaminating the oil. RPM pre-machined to remove failed repair, Laser Clad with 420 SS, and post machined to correct tolerances.

coal pulverizer

coal pulverizer

Power generation industry studies have shown that coal pulverizers are an area where improved equipment reliability is badly needed. The Electric Research Institute (EPRI) has determined that 1% of plant availability is lost on average due to pulverizerrelated problems.1 EPRI also identified oil contamination and excessive leakage as two areas where pulverizer drive train failures account for 53% of pulverizer problems.

Pulverization is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.

This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it.

Grinding Action is carried out by a series of hinged or fixed hammers revolving in an enclosed chamber with wear resistant plates. The hammers impact on the coal, crushing it against the plates. Further pulverization is achieved as the smaller coal particles are ground through attrition against each other and the grinding face.

This mill uses hydraulically loaded vertical rollers resembling large tires to pulverize raw coal fed down onto a rotating table. As the table rotates, the raw coal is pulverized as it passes underneath the rollers. Hot air forced through the bottom of the pulverizing chamber removes unwanted moisture and transports the pulverized coal dust up through the top of the pulverizer and out the exhaust pipes directly to the burner. The more recent coal pulverizer designs are Vertical Roller Mills. Figure 2 shows a cutaway view of a Babcock and Wilcox MPS Pulverizer.

Mills A ball or roller between two races or rings provides the grinding surfaces on which pulverization occurs. One or both of the races may rotate against a ball or roll (in a Ring-Roll Mill the rolls may rotate while the ring is stationary). Ring-Roll (Bowl-Mill) and Ball-Race Mills comprise the majority of coal pulverizers currently in service at power generating facilities.

In this design the grinding rolls are stationary, while the ring (or bowl, as it is sometimes called) is rotated by a worm gear drive. Powerful springs force the grinding rolls against the ring, providing the pressure required to pulverize the coal.

Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner. Coal that has not been pulverized into fine enough particles cannot be blown out of the top of the unit; it falls back to the ring and roll to be further pulverized.

The gears and bearings in the gearbox are oil lubricated. Fine coal particles and wear metals from grinding surfaces enter the lube oil through worn bearing and shaft seals, as well as being inhaled through reservoir vents. Historically, the design of pulverizers has been based on the expectation of few drive system problems under prescribed operation and maintenance. In practice, this has often been found not to be true.

Many coal pulverizer designs do not incorporate any filtration in their lube circuits. The pulverizers that do not incorporate filtration use coarse filtration such as 40-micron cleanable mesh or 200-micron cleanable, stacked disk filters. Such OEM-supplied filtration is often unable to keep up with the inherently high ingression rate. This results in contamination levels often exceeding ISO code 30/30, particularly on older designs. This high level of contamination can severely diminish bearing, gear, pump, and seal life, leading to premature need for replacement or rework. Coal pulverizer downtime can be a major factor in reducing overall plant availability and reliability.

Upgrade to Achieve Total Cleanliness Control (See diagrams on back page) The majority of pulverized coal particles are in the 4-30m range, with 70% of these particles smaller than 10m. Ingression rates vary with manufacturer, model, and age ofunit, with older units usually admitting contaminants faster than newer ones. Particulate contamination in the lube system can result in rapid damage to critical components.

In order to protect the coal pulverizer lube system components, Pall recommends maintaining a fluid cleanliness level of ISO 16/13 or better. This can be accomplished through the use of Ultipleat SRT AS grade (12(c) 1000) or finer filters. Ultipleat SRT filters, with their high particle removal efficiency and dirt-holding capacity, are ideally suited to cost-effectively control contamination in this high-ingression application.

When upgrading in-line filtration, a Pall Duplex Assembly is recommended so that elements can be changed out while the pulverizer is operating. Although putting filtration in-line is preferred, difficulty in getting system specifications from the OEM, combined with the typically low pump pressure associated with this application, may make kidney loop filtration a more viable alternative. Reservoir volumes typically vary from 15-300 gallons.

A 20% reservoir volume per minute flow through a kidney loop is generally sufficient to overcome the ingression rate of most applications. The high-viscosityof gear lube oil (2,200 SUS at operating temperature) along with the inherently rapid ingression rate usually associated with these units makes it necessary in most cases to utilize at least one UR619 housing with a UE619 element (12(c) 1000 or finer) for every 50 gpm of flow to provide superior filtration with long element life. Since the pulverizers come on- and off-line, it is important to size the system for the oil viscosity at the coldest possible ambient plant temperatures. Line diameters in the kidney loop should be large enough to facilitate flow of highly viscous lube oil.

Other applications where Pall high-performance filtration is useful include coal-carrying cars and conveyor belts. Many of these applications have both hydraulic and lube systems that are vulnerable to coal dust contamination. This equipment is required to transport the coal stored on-site to the coal pulverizers. Because this equipment is essential to theoperation of the power plant, it is critical that this equipment be free from contamination-related failure.

In March 2003, a major Canadian utility derated its Unit 4 due to a failure of the B mill. The mill was expected to be out of service for about a month. With lost production of approximately 864 MWh per day, the total estimated revenue loss was around $2,000,000. Repair costs for this outage added up to more than $400,000 due to the severity of the damage to drive train components. An analysis concluded that there were multiple causes of this problem, including poor predictive/preventive maintenance practices and poor oil cleanliness.

Pall provided a filter housing for a sixmonth trial to show that oil cleanliness could be improved to industry standards and maintained without the incurrence of substantial element costs. Oil cleanliness went from 20/19/17 to 18/16/13 in approximately 2 hours and has been maintained at this level since.
