The principles of coal combustion and gasification have been well understood for over 100 years. Coal gasification was widespread during the late 1800s, providing coal gas for inner-city lighting and power generation. In recent years, coal gasification has experienced a rebirth because of increasing fuel and electricity costs. At Moss we believe that because of the price and availability of coal, our combustion and gasification systems will become more viable in the approaching years and are committed to provide cost effective and emission friendly systems that keep operating expenses competitive with world utility cost.
Moss System Advantages:
Moss coal combustion, gasification and co-generation technologies has a number of advantages over competitive systems that make it very cost effective to replace natural gas and electricity installations. Some of these advantages are as follows:
- Low Capital Cost - Moss coal equipment designs and low operating overhead allows us to generally be the least expensive vendor on a project. This is due to our very versatile and experienced engineering group that is capable of examining a project and almost always simplify the project or in some cases utilize existing jobsite equipment to accomplish the goal of constructing a dependable and low cost energy system. Whenever we compete directly, we generally are less expensive while supplying superior equipment and technology. Another reason for our low cost equipment and systems is our ability to purchase at the most competitive rates. In addition, our coal burning designs generally require minimal emission control equipment such as mechanical collectors, baghouses and electrostatic precipitators. Our systems are simpler, less expensive and easier to operate compared to conventional combustion and co-generation systems.
- Low Operating & Maintenance Cost - Moss does not make profits by selling spare parts or service/repair hours. We have no desire to make most all of our profits in the aftermarket business like a lot of our competition. Therefore, we make an concerted effort to design systems that are less expensive to operate and maintain. Properly selected refractory, adequately sized grates, large furnace volumes and low system gas velocities promotes less system stress resulting in a extended combustion chamber and boiler life. A properly sized combustion chamber reduces particulate carryover, minimizes tube damage and promotes cleaner tube surfaces; therefore increasing boiler efficiency. We believe that our system designs will greatly increase the boiler life and significantly reduce the yearly operational and maintenance cost.
- System Results - Our simple to operate yet very complex PLC control system is the heart and soul of all Moss solid fuel combustion systems. The controls make the difference in our systems productivity and the low emissions leaving the stack. Moss generally uses all variable frequency drives for proper control of the fans and fuel feed system on all Moss combustion systems. Our control and combustion chamber design allows our systems to operate at lower temperatures promoting lower NOx emissions and because of our high pressure drop and properly designed overfire air system, the systems meets most all CO requirements without the need of auxiliary equipment. All of our combustion systems are capable of very high turndowns. These features results in minimal operator intervention and contributes to low operating cost.
