Combustion and Performance Optimization
Nalco Mobotec has been an industry leader in providing air protection services. Maintaining optimum combustion and boiler performance increases not only overall boiler efficiency but also conserves fuel and maintains low emissions rates which is a direct result in overall savings. As the emissions regulations require additional equipment and technologies the flexibility of boiler operation decreases.
Soot blowing Optimization
Nalco Mobotec can optimize your existing soot blowing system for increased performance. Whether the issue is excessive slagging, high steam temperatures, low steam temperatures, high furnace exit gas temperatures, or excessive tube erosion Nalco Mobotec can perform a detailed analysis of your existing system and recommend a solution to your existing problem.
Nalco Mobotec provides one of the best SNCR systems in the industry and our field service staff is well versed in not only our systems but also competitors system. Whether the issue is purely reliability based or performance based we can provide a full condition assessment and optimization of your current SNCR system. Many times we can upgrade existing SNCR’s to provide better control, performance, and reliability or we can simply optimize the current system for maximum NOx reduction. Poor system design can cause tube leaks, pendant corrosion, excessive ammonia slip, and poor NOx reduction performance. Nalco Mobotec is comprised of not only a field service group but also a comprehensive Research/Technology department and design engineering group capable of solving the toughest problems. NOx reduction via chemical injection using urea or an ammonia takes specific knowledge of droplet size, furnace mixing (penetration/coverage), temperature, gas velocities, and chemical processes to make a system perform at its best. Over the course of time a plant can unknowingly change combustion characteristics within the furnace without knowing it. The most significant of these changes is fuel quality which impacts pulverizer performance, air requirements, burner performance and finally emission levels. Equipment wear accounts for another subtle change within the system. All of these affect the combustion within the furnace whether it’s shifting temperature zones within the furnace, excessive CO, slag buildup, furnace gas velocities, and higher NOx formation. These factors all affect the performance capability, chemical utilization, and reliability of a SNCR. Annual tune-ups are recommended to ensure that maximum performance and chemical utilization of these systems are maintained.
