Vertical tube natural circulation evaporators
Bradley N. Jackson, Nooter/Eriksen Inc., Fenton, MO, United States
Abstract
Vertical tube, natural circulation evaporator designs have been the go-to technology in the combined cycle power industry for decades. They are reliable, easy to construct, and have a high turndown ratio. They do not require heavy duty circulating pumps and thus avoid the operating and maintenance costs associated with such pumps. The use of vertical tube, natural circulation evaporators also increases the operating flexibility of a power plant.
