Fireside Chemical Treatment

Nalco Mobotec Fireside Chemical Treatment Programs: How They Work

Nalco Mobotec’s Fireside Chemical Treatment (FCT) programs are applicable to any combustion system whose availability and efficiency are diminished by slag or fouling deposits, whether boilers, kilns, incinerators, or others. These slag and fouling deposits result from the combustion of ash-producing fuels such as coal, heavy oil, wood products, and other biomass and waste materials. Nalco Mobotec FCT employs a variety of proprietary slag-inhibiting or combustion-enhancing chemistries. These products (when combined with Nalco Mobotec’s unique application technologies) are designed to maximize program effectiveness and minimize customer cost. FCT programs also include the consulting and mechanical maintenance services of Nalco Mobotec professionals to help ensure that desired results are achieved.

Chemicals injected into the furnace through Nalco Mobotec FCT programs actually change the molecular composition of slag deposits as they form. Not only are the deposits themselves dramatically decreased, but the resilience of remaining deposits is lessened, so that soot blowers and other slag removal devices can clean surfaces more thoroughly and efficiently.

Technological and Financial Benefits of Nalco Mobotec FCT Programs

Certain FCT formulations offer the added ability to enhance combustion efficiency and reduce unburned carbon that may be part of ash material. Nalco Mobotec uses a custom design process to develop an application strategy that maximizes the efficiency of each system’s applied chemistry. The benefits of this approach include:

• Reduction of fuel required to keep a system running at peak performance by as much as 5 percent
• Maximized production capability while a system is online
• Extended run times between offline cleanings by up to 100 percent
• Minimized costs for maintenance (removal of slag and fouling) and equipment repairs, such as those necessitated by falling slag

A typical Nalco Mobotec FCT program begins with a complete system survey that may involve computerized modeling of the combustion system. From this, a custom solution is developed that best enables a high return for the customer. Nalco Mobotec provides all application equipment and chemicals necessary to achieve desired results. In addition, Nalco Mobotec offers unique monitoring and laboratory analysis to diagnose slag, fouling, and combustion-related problems. We also help ensure that successful solutions are implemented at the customer site. The goal of every program is to optimize efficiency while lowering the customer’s total cost of operation.
