Complete fabrication and assembly performed by our experienced teamCustom jigs are used for assembly to ensure proper alignment of all moving partsQC job traveler for each burnerCoal and boiler operating data reviewTest data reviewCFD modeling of air flow and chemical species of combustion3D Solidworks models of the combustion system is made after field measurements.This helps with mechanical design and reducing installation problems.Once the baseline CFD model is completed, the addition of Low NOx burners with and without Overfire Air can be tested.Elevation changes of the OFA can be tested as well as various mill and burner combinations and operating conditions.To maximize NOx reduction when overfire air is used, burner throat modifications are supplied for optimum performanceSilicon carbide interlocking segments and 309 stainless steel retaining ring

Stationary Coal NozzlePower & Industrial Services full line of engineered replacement and upgraded stationary coal nozzles are available with the following features: Providing double the wear life of cast iron, all nozzles can be cast from Power & Industrial Services proprietary CryosteelBolted or integral stainless steel tipAll nozzles available with ropebreaker fuel distribution kickers.Complete shop assembly of nozzle, linkage and tipAdvantages of the Ropebreaker Coal NozzleNo increase in pressure drop from kickersSignificant improvement in fuel distribution exiting the tip resulting in a more stable flame which allows for better combustion control, reduced slagging and lower NOxDisruption of the coal rope significantly reduced localized erosion and increased tip life

P&I Boiler Access Door Features & Benefits:Doors available with or without wallbox and bent tube panelBent tube panels can be made from smooth or weld overlay tubing and come completely assembledAll doors come with P&Is unique replaceable refractory cap shop installed (no field pouring of door refractory needed!)All doors rated for 2800F continuous operation 3000F max excursion temperaturesHeavy duty cast door resists warping to maintain gas seal for the life of the doorYoke and door swing opposite of each other to allow for maximum open areaSome wallboxes may be shop filled with refractory to eliminate any field refractory workP&Is unique combination of refractory cap, air gap, and rigid insulation provide industry best cold face temperatures

The patented Thru-Bolt system developed by Power & Industrial Services for split ring tube alignment castings can be installed by a single person in far less time than required by standard procedures requiring two or more people or use of come-a-longs to pull tubes into alignment. Download Brochure Features & BenefitsOur castings come in either standard 2 high or heavy-duty 3 high. Power & Industrial Services can recommend an alloy based on your needsBenefits of 3 heavy-duty castingsProvides additional strengthParticularly in longer castings where capturing more tubes in one casting can cause additional casting stressProvides more material to withstand extreme operating temperaturesOur new U-Clamp and bar alignment method offers the fastest and most secure method of aligning pendant rows without having to weld to your tubes. This eliminates potential tube leaks.

Online Pipe-to-Pipe Measurement & Control SystemThe Coal Flow Analyzer is a real time pipe-to-pipe distribution monitoring system. Powered by MIC systems, this microwave based solution continuously omits waves into the coal piping. Variations in the mass flow of the coal are detected and the real-time pipe-to-pipe distribution is displayed on the local computer. When paired with either the P&I Adjustable Orifice Valve or the Lehigh CoalControl Adjustable Riffle, the Coal Flow Analyzer provides an accurate, reliable, and easy to use system for performance and combustion optimization. Based on pipe to pipe coal distribution data, each burner air register can be tuned to achieve the lowet possible NOx as well as reducing slag formation that can result with a heavily loaded pipe. BenefitsPortable system can be used across multiple mills and multiple unitsEPRI TestedNo pressure dropDoes not need to be calibratedHighly accurate and reproducibleFits into existing sampling portsHelps reduce fuel consumptionCan be directly tied into DCSDust free fitting allows for clean testingCoal flow velocity measurementPortable System Portable SystemThe compact Portable System can be used to gather data on a per mill basis. Using existing sample ports, pipe to pipe distribution can be gathered in a few hours. Portable system can be easily taken to other units on the same site or to other plant sites. This system should be part of the equipment of every utilitys combustion optimization team.

EU Tech Coalsizer Coal Fineness Euflame FEGT Continues Monitoring Fineness Testing and Mill OptimizationThe coal particle size spectrum has a strong impact on the combustion process. It influences ignition delay, combustion efficiency, LOI, NOx & CO, as well as slagging and fouling. Despite the significance of this property, there has not yet been a robust and easy to handle system for the online measurement of coal fineness inside the pipe. EucoalizerSolutionEUcoalsizer solves this problem. The laser based system measures the particle size distribution and the coal as well as PAPF flow. By traversing the lance through the pipe, a particle size distribution along the cross-section of the coal pipe can be measured. The time of transition method covers a very wide range of particle sizes from 20 m to 4 mm. The simultaneous measurement of coal and air flow proves to be an essential prerequisite for fuel line balancing and coal flow optimization. SpecificationsThe EUcoalsizer system comes turn-key and can be directly applied via an adapter to the coal pipe. The system delivers results on-line and instantaneously. Handling is very easy via an intuitive graphical user interface. The system has many helpful features to support analysis and optimization (report generator, data base, etc.) Rugged industrial design for exposure to highly abrasive flow conditionsEffective lance length > 1 m (covering pipe diameters up to 625 mm 25)Probe diameter 51 mm (2)BenefitsOn-line combustion optimization (reducing LOI, emissions, slagging)Pulverizer performance monitoringCondition-based pulverizer maintenanceCoal flow and airfuel distribution tuningReduction of fuel consumptionReal time, dynamic Rosin Rambler chartAccurate airfuel ratio measurement

PRB Coal Bunker Cleanout System The high volatility of PRB coal has led to unique coal handling techniques. Coal bunker fires can start in a few days after a mill or unit is shut down. Emptying the bunkers has become standard operating procedure for PRB users. Power & Industrial Services has designed a simple and economical method to safely unload a coal bunker without the need for a vacuum truck. PRB Coal Bunker Cleanout Is installed between the coal feeder and the pulverizer.
