摘要： A method for improving pulp mill steam cycle efficiency includes the steps of providing at least one deaerator tank having a first pressure, and lowering the pressure of said deaerator tank to a second pressure. Feedwater is supplied to a pre-economizer, where it is heated. The water is then delivered to at least one feedwater heater, where it is heated. The water is then delivered to an economizer. By this method boiler steam rate is increased while boiler efficiency is maintained and turbine extraction for deaerator and feedwater heating is minimized.

摘要： An enhanced steam cycle utilizing a dual pressure recovery boiler with reheat. A dual pressure designed recovery boiler furnace is provided with a lower furnace and an upper furnace. The lower furnace is operated at a lower temperature to prevent or reduce corrosion of the lower furnace wall tubes. The lower furnace can be either a low pressure natural circulation steam generating (drum) system or economizer. The upper furnace operates as a high pressure natural circulation steam generating (drum) system, or as a once-through supercritical steam generating system at higher temperatures and pressures permitting implementation of higher efficiency reheat steam cycles.

摘要： An enhanced steam cycle utilizing a dual pressure recovery boiler with reheat allows a large increase in electrical generation with various turbine cycles while overcoming traditional lower furnace material limitations. A dual pressure designed recovery boiler furnace is provided with a lower furnace and an upper furnace. The lower furnace is operated at a lower temperature to prevent or reduce corrosion of the lower furnace wall tubes caused by the reducing environment. The lower furnace can be either a low pressure natural circulation steam generating (drum) system or economizer. Unlike the lower furnace, the upper furnace is not exposed to a reducing environment and is therefore not as susceptible to severe corrosion rates. The upper furnace is operated at higher temperatures and pressures which permit implementation of higher efficiency reheat steam cycles. The upper furnace thus operates as a high pressure natural circulation steam generating (drum) system, or as a once-through supercritical steam generating system. The dual pressure recovery boiler can thus be coupled to a variety of condensing, non-condensing or a combination of condensing and non-condensing turbine cycles to provide a large increase in electrical generation.
摘要翻译：利用具有再热的双压力回收锅炉的增强的蒸汽循环允许在克服传统的较低炉材料限制的情况下，具有各种涡轮循环的发电量大大增加。双压设计的回收锅炉炉具有下炉和上炉。下炉在较低的温度下运行，以防止或减少由还原环境引起的下炉壁管的腐蚀。低炉可以是低压自然循环蒸汽发生（鼓）系统或节能器。与下炉不同，上炉没有暴露在还原环境中，因此不会受到严重的腐蚀速率的影响。上炉在更高的温度和压力下运行，这允许实现更高效率的再热蒸汽循环。因此，上部炉子作为高压自然循环蒸汽发生（鼓）系统，或作为一次通过的超临界蒸汽发生系统。因此，双压力回收锅炉可以耦合到各种冷凝，非冷凝或冷凝和非冷凝涡轮循环的组合，以提供大量的发电增加。
