Greenbank India Private Ltd | Company Profile

Improvement of fuel distribution across the burner zone (andacross the boiler load range) is key to delivering improvedcombustion performance and associated coal­fired boilerperformance optimisation.

This is achieved through measurement and understanding of fuelflow and associated velocity specific to each burner PF pipeconfiguration followed by the necessary adjustment to fuel flowusing appropriate flow­balancing technology. This helps facilitateimproved alignment of air flow and fuel flow, thereby helping toestablish the required air­to­fuel ratio (AFR).

Addressing improved fuel distribution and associated burner­to­burner AFR is fundamental to managing emissions to air suchas NOx, CO, particulates, etc. It is also fundamental to addressingother combustion performance­related challenges associatedwith fireside corrosion and carbon­in­ash as well as slagging andfouling within the furnace. Delivery of improved combustionstability is also fundamental to improved flexible operations andminimum stable generation (MSG).

In addition to fuel distribution, PF particle size distribution canhave a significant impact on burner combustion performance.Good management of PF particle size distribution throughappropriate management of the milling system is essential.

Therefore, on­line measurement and monitoring of mill exit PF particle size distribution will help facilitate appropriate mill management and help ensure fuel is delivered to the burner zone at the required particle size distribution.

Whilst addressing and managing key influencing factors such asburner­to­burner fuel distribution, fuel quality and particle sizedistribution are essential to delivering improved combustionperformance with commensurate improvement in boilerperformance, there are other factors that must be addressed.Management of combustion zone stoichiometry (theoretical plusexcess air necessary for complete combustion) is a further keyelement that must be addressed.

Combustion zone stoichiometry is managed via the addition ofappropriate primary and secondary air flow to the furnace.Getting the balance right is extremely important but is oftenundermined via excessive ‘uncontrolled’ furnace air ingress(tramp air) or in­leakage at other locations such as the air­heaterand duct seals.

Key to facilitating improved combustion performance is thebalancing of fuel distribution across the burner zone,management of fuel quality and PF particle size distribution andminimising uncontrolled air ingress to ensure the combustionzone operates at the required AFR.

Greenbank India Private Ltd | Company Profile

Greenbank’s award winning products and services help deliver improvements to large combustion plant, improving not only efficiencyand greenhouse emissions but health and safety in the workplace.

GravMaster® Pressurised Gravimetric Feeder.Designed to accurately discharge unpulverised fuel intoa pulverising mill. Improves particle fineness and milling

throughput, reduces bunker blockages and fires, andimproves efficiency by keeping hot air away from the

feeder and bunker.

CoalFlo® PF Balancing Damper.Designed to balance PF distribution from multi­outlet mills. Improving PF distribution providesboth plant flexibility in operation and the abilityto run more efficiently on high and low load.

VARB® PF Diffuser.Designed to break PF roping inherent in the conveying offine particulates in air. VARB technology can guaranteegood distribution of particulates at splits in pipelineswhich is necessary for both plant efficiency andreduction of greenhouse gases such as NOx and CO.

MillMaster® Particle Size Analyser.Designed to accurately measure particulates taken from aPF or dust ducting. Measuring the size of PF particulatesmonitors the performance of the pulverising mills orexhaust gases and advises the operator of anydeterioration of plant performance.

PFMS® PF Monitoring System.Designed to provide rapid on­line measurement of

pulverised fuel distribution in burner pipelines.Accurate and rapid on­line measurement gives theoperator the ability to optimise PF distribution and

stoichiometric conditions under different loads.

G­CAM® Carbon­in­Ash Analyser.Designed to rapidly analyse the level of unburned

carbon­in­ash carried in flue gas. Assessing levels ofcarbon­in­ash provides the operator comfort over

boiler stoichiometric conditions which helps ensurefly­ash is suitable for re­sale rather than landfill.

GA200® Series Acoustic Steam Leak Detection.Designed to provide advanced warning of

high­pressure tube­leaks on large combustion boilers.The system accurately identifies and locates a boiler

tube­leak at early stages against the noise of anoperational boiler.

Materials HandlingProducts & ServicesGreenbank Materials Handling products and services offers both standard and bespoke product and systems based designs andsolutions for companies operating in the power, cement, steel, minerals, glass, pharmaceuticals and ports and terminals markets. GMH is also at the forefront of developing bulk materials handling solutions for the new and emerging biomass market.

Continuous Weighing ProductsGreenbank now offers a full range of industrial weighing equipment, including belt­weighers, feeders, weigh screws and silo weighing.Using the GBWI­436 dynamic belt­weigher controller enables continuous calculation of the rate of material flow over the belt and thetotal quantity of material transferred.

Controlled Flow ChutesInefficient designs can result in the degradation of material,increased spillage, generation of dust, increased wear onconveyor components and increased power consumption.

Another knock­on effect of poor design can be increased costsstemming from spillage, demurrage, maintenance and additionalrepairs.

Greenbank provide chute designs that increase the lifeexpectancy of conveyor components, reduce downtime andminimise maintenance costs.

From conception to installation, our specialised engineerscombine the latest techniques in CFD and DEM with expertdesign skills to produce high performance chutes which reducedowntime and improve operational efficiency.
