摘要:
Systems and methods for selectively producing steam from solar collectors and heaters, for processes including enhanced oil recovery. A system in accordance with a particular embodiment includes a water source, a solar collector that includes a collector inlet, a collector outlet, and a plurality of solar concentrators positioned to heat water passing from the collector inlet to the collector outlet, a fuel-fired heater, a steam outlet connected to an oil field injection well, and a water flow network coupled among the water source, the solar collector, the heater, and the steam outlet. The system can further include a controller operatively coupled to the water flow network and programmed with instructions that, when executed, direct at least one portion of the flow through the solar collector and the fuel-fired heater in a first sequence, and direct the at least one portion or a different portion of the flow through the solar collector and the fuel-fired heater in a second sequence different than the first sequence.

A direct-fired, pulverized coal-fired furnace (2), wherein the fuel supply system is modified so that a load carrying pulverizer (10) supplying pulverized coal to the furnace through a plurality of burners (4) may simultaneously also supply pulverized coal to a storage bin (16) for storage therein until needed to start-up, warm-up and stabilize the low load firing of the furnace (2) at a later time.

摘要:
An arrangement (100) and a method for handling purged alcohol-based fuel originating from an alcohol fuel system (108) configured to fuel an alcohol fueled engine (112), the arrangement (100) comprising: a boiler system (102) comprising a burner (104) and a fuel inlet (111) configured to selectively supply a fuel and thereby selectively sustain a primary flame in the burner (104) for production of heat and/or steam in the boiler system (102), a purge connection (140) configured to receive a purge mixture purged from the alcohol fuel system (108) using an inert gas, the purge mixture comprising a mixture of the inert gas and purged alcohol-based fuel, and a vapor-liquid separator (141).
