Abstract: A system for detecting abnormal situations associated with a heater in a process plant receives statistical data associated with the heater unit. The statistical data is analyzed to detect whether one or more abnormal situations associated with the heater exist. The statistical data may comprise statistical data generated based on pressure variables sensed by one or more pressure sensors associated with a furnace, a stack, a fuel supply, etc., associated with the heater. Additionally, the statistical data may comprise statistical data generated based on temperature variables sensed by one. or more temperature sensors associated with the furnace, the stack, etc. If an abnormal situation is detected, an indicator of the abnormal situation may be generated.

Abstract: A method of determining the amount of air flowing through an outside air damper (24) of a recirculating air heater (10) includes the steps of sensing an amount of airflow flowing through the damper, recording the amount of airflow and a damper position value at a plurality of damper positions, and interpolating a curve relating the amount of airflow to the damper position for all damper positions between a minimum damper position and a maximum damper position. Once the amount of air flowing through the outside air damper is determined from a position on the curve, the concentration of carbon dioxide (CO2) within a building space can be calculated and/or determined to be within acceptable limits.

Abstract: A method and apparatus to conduct O 2 /CO 2 combustion or oxygen-enriched combustion. The boiler exhaust gas passes through a Gas Primer Sector (GPS) combined with the boiler to effect heat transfer to the combustion gas in indirect counter-flow heat exchange. Sharply reduced gas flows result from using largely moisture-free CO 2 as diluent for O 2 in the combustion gas which allows long residence time at low velocity for maximum heat transfer from the exhaust gas to the combustion gas. Most particulate drops out and most moisture is condensed from the cooled mostly CO 2 exhaust gas. The larger portion is blended with oxygen for the combustion gas and reheated and returned to the boiler through the integrated GPS; the smaller portion is cleaned and separated, the CO 2 released or recovered. The complete exhaust gas-combustion gas cycle may be 30 to 90 seconds and preferably about 60 seconds. The high heat capacity of CO 2 allows a much higher oxygen content in the combustion gas compared to open-cycle air combustion with a large nitrogen content of lower heat capacity. Efficiency is increased. Final exhaust gas separation and recovery is simplified. Condensate is processed to boiler feedwater or potable water quality. NO x is eliminated, mercury fume captured and CO 2 output reduced.

Abstract translation: 进行O2 / CO2燃烧或富氧燃烧的方法和装置。 锅炉废气通过与锅炉组合的气体入口部分（GPS），以在间接逆流热交换中实现对燃烧气体的热传递。 大量减少的气体流量是由于使用大部分不含水分的CO2作为燃烧气体中的O 2的稀释剂，其允许在低速下长时间停留时间以从废气到燃烧气体的最大热传递。 大部分颗粒物流出，大多数水分从冷却的大部分二氧化碳废气中冷凝。 较大部分与氧气混合用于燃烧气体，并通过集成GPS重新加热并返回锅炉; 清洁和分离较小的部分，释放或回收CO 2。 完整的废气燃烧气体循环可以是30至90秒，优选约60秒。 与具有较低热容量的较大氮含量的开式循环空气燃烧相比，CO 2的高热容量允许燃烧气体中的氧含量高得多。 效率提高。 最终废气分离和回收简化。 冷凝水被加工成锅炉给水或饮用水质量。 NOx被消除，捕获汞烟并减少CO 2输出。

Abstract: The present additional control strategy has been developed to allow the gas turbine to operate at lower load or at other conditions where the total fuel required by the gas turbine is not optimum for full combustion of the fuel. The present invention manages air that bypasses the catalytic combustor and air that bleeds off of the compressor discharge. The bypass system changes the fuel air ratio of the catalytic combustor without affecting the overall gas turbine power output. The bleed system also changes the fuel air ratio of the catalytic combustor but at the cost of reducing the overall gas turbine efficiency. The key advantage of a catalytic combustor with a bypass and bleed system and the inventive control strategy is that it can maintain the catalyst at optimum low emissions operating conditions over a wider load range than a catalytic combustor without such a system.
