A shop-assembled solar receiver heat exchanger having an arrangement of heat transfer surfaces and a vertical steam/water separator structurally and fluidically interconnected thereto. A vertical support structure is provided to support the vertical separator and the heat transfer surfaces. The vertical support structure is bottom supported, while the vertical steam/water separator and heat exchanger heat transfer surfaces are top supported from the vertical support structure. The vertical support structure provides structural support and rigidity for the heat exchanger and a means by which the heat exchanger can be picked up and lifted for placement at a desired location. A fabrication/transport/lifting fixture is provided which facilitates fabrication, assembly, transportation and erection of the heat exchanger from the shop to the field. The fixture supports two trunnion shafts attached to the support structure of the receiver. Lifting lugs would be located on the top end of the support structure. Upon arrival at the job site in the field, a crane lifts the heat exchanger receiver to vertical, rotating about the trunnion shafts on the fixture, and then lifts the heat exchanger receiver for placement at a desired location.

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.

A fluid flow circuit for a boiler having a combustion chamber and an exhaust passage. In one embodiment there is provided at least one upflow evaporative generating bank module in the exhaust passage and at least one downflow evaporative generating bank module in the exhaust passage, positioned downstream of the upflow module. One or more upper downcomers are connected to a steam drum and supply water to the lower header of the upflow module and to the upper header of the downflow module. If needed, the convection pass wall enclosures can also be fed by the upper downcomers to their upper inlet headers. One or more lower downcomers may be connected to each lower header of the downflow module (and to the lower outlet headers of the convection pass wall enclosures) for supplying the water to a plurality of furnace circuits which extend along the combustion chamber in the boiler. The opposite end of each furnace circuit is connected to one or more risers which, in turn, are connected to the steam drum. The upper header of the upflow module is also connected to the steam drum through one or more risers for completing the circuit.

A steam generator circulation system is provided and includes a boiler feed pump for forcing water through an economizer, and through the waterwall tubes of an evaporator. A separator receives a mixture of steam and water and sends the steam to a steam utilization unit such as a superheater. A valve is provided below the separator. If the valve is open, the saturated water from the separator is mixed with feedwater and recirculated through the tubes of the evaporator. If the valve is closed, recirculation is terminated. At loads below the critical point, the valve below the separator system would be open and the boiler would operate like a natural circulation drum boiler. At loads above the critical point, the valve below the separator system would be closed resulting in a boiler that operates like a once-through boiler.

122467, 122470, 122482

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.

A conical cyclone separator for separating steam from water in a steam/water mixture supplied to a steam drum of a boiler, comprises a conical portion with upper and lower cylindrical portions. Unlike conventional separators which include a tangential inlet extending the axial length of the conical portion of the separator only, the disclosed separator has an inlet which extends by approximately 20% of its length over the lower cylindrical portion of the housing and is vertically elongated over the inlet of conventional separators.

A dual-exposure heat absorption panel is disclosed, which can be used in a solar receiver design. Generally, the heat absorption panel includes a tube panel through which a heat transfer fluid is flowed to absorb solar energy from heliostats that are focused on the tube panel. A structural support frame surrounds the tube panel. A stiffener structure runs across the exposed faces of the tube panel. The headers and other support structures on the periphery are protected by use of a heat shield.
