We know that being in the power generation industry you face problems with consistent coal qualities because of a need for consistent quality for your boilers. In addition, increased environmental regulations for S02 and particle emissions present further challenges to the power industry. This results in increased need for Real Time Analysis at power plants. Real Time Analysis will to enable you to blend your coal to meet required specifications and help increase plant efficiency through a decrease in forced outages and de-rates. SGS will work with you to ensure that your On-Line Analyzer System optimizes your operation and helps you meet the challenges facing power generators today.
As an independent, leading supplier of innovative, technologically advanced services to the power generation industry, SGS is uniquely positioned to partner with you to improve your efficiencies, and enhance your profitability. All SGS work is done in accordance with internationally accepted standards such as ASTM, EPA, ISO and JIS. We are dedicated to providing you with value-added solutions that reduce risk, enhance value and maximize returns at each step in your power generation value chain. Our reputation depends on your complete satisfaction.
Through our global network of operations, SGS can deliver a broad spectrum of independent evaluation services to power generators worldwide. This is aimed at reducing your risks and maximizing your profits. Through our team of professionally qualified engineers and support staff we can provide you with technical expertise in the areas of:
Mechanical Sampling Systems
Risk associated with inaccurate evaluation of coal is managed by selecting the proper Mechanical Sampling System (MSS). SGS has a team of professionally qualified engineers and support staff that have the experience needed to provide services related to your new or existing Mechanical Sampling Systems. We have 25 years experience in the design, supply, installation and commissioning of client-dedicated, site-specific MSS, with more than 300 SGS-designed systems operating in over 20 countries worldwide.
Qualified SGS personnel perform technical audits and provide on-going maintenance to ensure the best possible sampling from your equipment. SGS will maintain a quality assurance program for your Mechanical Sampling Systems in accordance with international standards including:
- Inspection of the Mechanical Sampling Systems
- Bias testing of the Mechanical Sampling Systems
- Collection and analysis of the samples from your Mechanical Sampling Systems
- Modification of the existing MSS to improve the performance and/or eliminate bias
- Technical advice on the operation of the sampling system
- Breakdown repairs

To design an effective MSS, detailed information about the location of the MSS and the material to be sampled is needed (including its top size, surface moisture content and material handling characteristics). A site visit is often required to ensure your MSS design meets the design criteria defined by ASTM, ISO or other global standards. SGS will use tried and proven designs and modify these, where necessary, for each new application. Through this process we provide you the best and most cost effective solution to your sampling problems.
On-Line Analyzer Systems
SGS is a global leader in the field of on-line analyzer systems (OLA), providing complete design, installation and support services for your new or existing OLA System. An OLA system will allow you to monitor, control and optimize your processes as they occur and allow you to undertake process modifications when they are beneficial to operations. This can have a substantial, often overwhelming impact, on your facility’s profitability.
By properly blending your coal with an SGS designed on-line analyzer system, you can:
- Control and possibly eliminate your slagging and fouling problems resulting in a reduction of forced outages and de-rates
- Ensure maximum operational efficiency through consistent blending of coal
- More easily comply with environmental
regulations including S02 and particle emissions
- Operate nearer your design capacity without an increased risk of power fluctuations and environmental pollutant surges
SGS is unrivaled when designing and supporting OLA Systems for the coal industry. Once designed, our technical experts will install, commission, and calibrate the On-line System in accordance with globally recognized standards. Experienced SGS personnel using a continuous surveillance program will then provide ongoing support for your OLA System, including on-site inspections and recommendations for enhancements and improvements to your systems and procedures.

Sorting and Blending
Traditionally, coal producers use online coal analyzers to meet tight specifications for sulfur. However, given the power of On-line Analyzer Systems to sort coal consistently and accurately based on multiple quality factors (sulphur, ash, moisture, etc), there are many opportunities for coal producers to realize additional value from these systems.
Sorting based on quality allows raw coal that meets shipping specifications to be bypassed around the preparation plant. The yield of the preparation plant will increases, resulting in a more efficient and profitable operation. The ability to reliably blend various coal qualities to arrive at a specific product allows to:
- Blend lower cost poorer quality coals with high quality coals to exactly meet contract specifications
- Market and sell your coal to power generators more easily due to consistent quality
- Avoid rejected loads and quality penalties
SGS provides inspection and supervision services such as weight certification, sampling, chemical and quality analysis of coal and coke at most ports and major inland trans-shipment points. Whether you are selling, buying or transporting coal or coke, SGS is ready to assist and independently verify shipment weight and quality.

Laboratory Services
SGS provides the complete range of laboratory procedures to meet all your coal testing requirements. All laboratory analysis is performed in accordance with recognized global standards such as American Society for Testing and Materials (ASTM), International Standards Organization (ISO) and Japanese Institute of Standards (JIS). Quality assurance standards are constantly monitored through participation in numerous industry and standards body correlation programs, as well as in our own, unique round robin program administered through the Institute for Inter-laboratory studies. Our labs use concepts of total quality management (TQM) to ensure consistent operation on a daily basis.
Our qualified technicians operate in laboratories with state-of-the-art instrumentation, using industry best practices to provide you with complete, accurate and timely coal analysis. SGS coal analysis capabilities include:
- Proximate Analysis
- Ultimate Analysis
- Calorific Value
- Elemental Analysis
- Toxicity Testing
- Hardgrove Grindability Testing

Biofuels
Biofuels currently provide approximately 3% of all energy consumed in the United States. Using biomass fuels reduces the amount of waste and assists in the development and growth of agricultural products. This has been triggered by a combination of rapidly rising crude oil prices and national mandates on emission reduction, which have made the production and blending of biofuels commercially viable.
SGS has been involved in every aspect of biofuel production since the 1990’s. SGS monitors all aspects of the biofuel supply chain from plant choice for the farmer, through crop assessment, to monitoring the quality of feedstocks, and blending those biofuels into commercially distributed fuels. The SGS staff, both in the field and in the laboratory has examined all aspects of the various processes to make them more efficient and monitor trade volumes through the custody chain.
SGS has the experience and technical expertise to assist the industry with an extensive array of services focused on characterizing the biofuel, improving boiler efficiency, and ensuring compliance with contract specifications and local, regional, or federal regulations. As a partner, SGS can help a Customer increase a sustainable advantage by offering reliable analytical support to characterize biofuels under consideration.
If the intent is to buy or sell wood chips, grains, pellets, particles, sawdust, and fibers SGS can assist with the following services.
- Sampling, verification of quality (species, granulation, moisture content, ash content, dirt)
- Supervision of loading or discharge
- Vessel Hold inspections
- Vessel Draft surveys
