摘要： An extended water level range steam/water conical cyclone separator for separating steam from water in a steam/water mixture supplied to a steam drum of a boiler, has a housing comprising a conical portion with upper and lower cylindrical portions, and a conical vane plate. An open bottom extension sleeve portion for discharging water from the steam/water conical cyclone separator housing and connected to the lower cylindrical water outlet portion is provided such that the conical vane plate is located at an intermediate location between the upper conical portion and the open bottom extension sleeve portion of the lower cylindrical portion. Extended water level range capability is thus provided while maintaining adequate steam/water cyclone separator performance characteristics.

摘要： A control system for maintaining a desired heat exchanger outlet flue gas temperature across a range of boiler loads. The heat exchanger includes a plurality of tubular configurations in heat exchange contact with the flue gas with each tubular configuration having a separate feedwater inlet. Flue gas temperature control is achieved by modulating the feedwater flow rates through the tubular configurations. In a system having two tubular configurations, the overall heat transfer capacity of the heat exchanger may be reduced to maintain the desired heat exchanger outlet flue gas temperature by reducing feedwater flow through one tubular configuration and overflowing the other, while maintaining the total flow of feedwater through the heat exchanger substantially constant.

摘要： A gas temperature control system for maintaining a desired economizer outlet gas temperature across a range of boiler loads comprises a plurality of tubular configurations having surfaces that are in contact with the flue gas. Each tubular configuration, preferably, comprises a plurality of serpentine or stringer tubes arranged horizontally or vertically back and forth within the economizer, and each tubular configuration having a separate feedwater inlet. Heat transfer from the flue gas is accomplished by controlling the feedwater flow rates through the tubular configurations. In a temperature control system having two tubular configurations, the overall heat transfer capacity of the economizer may be reduced to maintain the desired economizer outlet gas temperature during low boiler loads by reducing feedwater flow through one tubular configuration and by overflowing the other tubular configuration, such that total flow of feedwater through the economizer is maintained substantially constant. Feedwater flow rate entering the economizer may be used to engage/disengage the economizer water internal proportion or bias system. Once engaged, the measured feedwater flow to the economizer is used to generate a proportioned or biased flow rate demand signal. The demand signal is then compared to the measured underflow proportioned or biased flow rate. If there is a difference between the demand signal flow rate and the measured flow rate, control valve(s) modulating the proportioned or biased flow is/are adjusted.
