One of the most valuable evaluations can you spend money on is to assess the current performance of your coal handling and delivery system. After all, this is where 100% of your dust and spillage originates from no matter what the coal. Our assessments target the areas most prone to causing dusting and spillage. We evaluate transfer points, load zones, open runs, roll-back/carry-back conditions, silo/bunker flow conditions, dust control effectiveness, and explosion potential. For a full scope evaluation, we combine this with a fire protection assessment to provide you a complete picture of your risk.

We evaluate areas that are typically overlooked by others such as excessive air velocities in transfer chutes and across silos and operational impact on pulverizers. For PRB CONVERSIONS, we provide a detailed report regarding the most vulnerable areas where greater risk can be expected.

Experiencing pluggage, spillage or excessive dusting? Transfer point flow dynamics control the successful performance of any coal handling system. The four major performance criteria that impact successful flow and control of dust are: Through-put, Spillage, Air Velocity and Fugitive Dust. We perform insitu testing that measures each of these criteria and provides you with a detailed report of passing and failing conditions. Don’t assume that the “latest and greatest” engineered chutes function as designed. Don’t spend money upgrading where you don’t need to....justify your upgrades based on hard test data. These tests are also recommended to verify OEM performance test results.

One plant or a fleet....don’t leave your fate to State or Federal Inspectors. Our OSHA NEP Assessment is performed just as OSHA would do it. Know your compliance status with all the regulations pertaining to dust referenced in CPL-03-00-008 BEFORE OSHA does. The scope of our assessment is extremely comprehensive, but in essence we assess the three major COAL HANDLING programmatic areas where deficiencies are almost always notable: Engineering & Design, Controls & Procedures, Training & Records.

An optional scope to the standard assessment is the measurement of fugitive dust. We use calibrated equipment to measure dust in mass concentration and present the data as OSHA TWA results. THE ONLY DIFFERENCE IN OUR AUDITS AND OSHA’S? WE DON’T ISSUE CITATIONS.

Ensuring that proper hazard boundaries have been established and electrical equipment within those boundaries are properly rated are on the OSHA ignition source hit list. We perform a detailed assessment to establish and document correct boundaries and assess the equipment within those boundaries for appropriate hazard classification. OSHA will ask to see your design basis documents.

As the EPA tightens its grip on the coal-fired industry, seemingly common modifications can trigger requirements that are often overlooked. NFPA 85 is the Boiler Safety Code adopted and enforced by the Boiler Safety Divisions of most states. While most plants were built before many of the current requirements went into effect, major modifications to the flue gas path (done at most plants since being built) triggers a little known retroactive requirement to reassess and modify the coal flow path between the feeders and the furnace, and to protect from furnace excursions that could cause pulverizer and coal pipe explosions. MFT’s leave this system in a very vulnerable state of explosivity. We have performed such assessments and would be pleased to provide a proposal to you.

Whether you are using bituminous or sub-bituminous coals or biomass, fires and explosions in bunkers/silos are a very real possibility. The major aspects that contribute to these events are fuel type, moisture, structural configuration, cone design, liners, flow, and ventilation. Impacted are explosion relief and fire control. This assessment will allow you to know how vulnerable your silos are to fires/explosions and what can be done to mitigate these vulnerabilities. We investigate recurring fire events. Dealing with a fire in silo is a major event that can lead to catastrophic results. See what training is available for firefighting under “Training Services.”

We provide pre-purchase risk audits of plants or we can provide a subject matter expert to participate and assist in a utility’s own internal audit team.

Balance of Plant Assessments (BOP) can be combined with a Targeted Coal Assessment or performed as a stand alone assessment. Items included in BOP assessments include risks associated with Turbine-Generators, Lube Oil & Hydrogen Systems, Boilers, BFP’s, Switchgear Rooms, Control Room Envelops and outlying buildings.
