Abstract: Solar energy generates steam in a “once-through” configuration without recirculation, with closely managed steam quality, to produce wet steam from high-contaminant feed water without scaling or fouling. Feed water is pressurized, preheated, and evaporated in a series of pipes exposed to concentrated solar energy to produce a water-steam mixture for direct distribution to an industrial process such as enhanced oil recovery or desalination. Water flow rates are managed based on measurements of solar energy and steam production to manage variations in the solar energy. Steam generator piping system uses continuous receiver pipe that is illuminated by segmented parabolic mirrors enabled to track the sun. Provisions for steam generator piping recurring maintenance are provided. Thermal energy from hot condensate and/or from low quality steam is recaptured and warms inlet water.

Abstract: A cleaning system and method for cleaning heat transfer surfaces in a boiler using a temperature measuring system for measuring and monitoring wall temperature of an annular wall of the tube of a lance of one or more sootblowers. Controlling a flow of steam or other fluid through the tube during the cooling portions of the strokes based on wall temperature measurements from the temperature measuring system. Infrared or thermocouple temperature measuring systems may be used. The steam or other fluid may be flowed at a default flowrate that may be substantially zero until the temperature measuring system indicates the wall temperature of the annular wall begins to exceed a predetermined temperature limit which may be the softening point of the annular wall. Then the steam or other fluid is flowed at a rate greater than the default flowrate.

Abstract: The purpose of the present disclosure is to solve the problems of a difficult operation or occurrence of corrosion damage to equipment caused by the attachment of ammonium sulfate salt, which is generated when unreacted ammonia (NH3 slip) and sulfur trioxide (SO3) in exhaust gas are bonded with each other when a selective catalytic reduction (SCR) is used to eliminate nitrogen oxides that are contained in the exhaust gas generated during the combustion of a boiler or the like, to a heat exchanger of an air preheater (APH) or the like installed at the rear of an SCR device and blocks a passage of the exhaust gas such that the pressure inside the boiler is increased. To this end, a dry ice cleaning device is installed at the front of an exhaust gas inlet in an air preheater such that the blocking of a heat exchanger caused by ammonium sulfate salt or the like is removed by spraying dry ice pellets, and at the same time, high-temperature steam spraying device is installed at a cold end of the air preheater so as to spray the steam in the same direction as that of air supplied to a boiler, thereby removing contaminants more effectively. Furthermore, in order to effectively prevent blocking which occurs in a cold end of the air preheater, dry ice is sprayed to the front of an exhaust gas inlet of the air preheater and also, to the front of a supply air inlet of the air preheater which is an opposite direction thereof, such that a cleaning effect is increased.

Abstract: Fouling of heat exchange surfaces is mitigated by a process in which a mechanical force is applied to a fixed heat exchanger to excite a vibration in the heat exchange surface and produce shear waves in the fluid adjacent the heat exchange surface. The mechanical force is applied by a dynamic actuator coupled to a controller to produce vibration at a controlled frequency and amplitude output that minimizes adverse effects to the heat exchange structure. The dynamic actuator may be coupled to the heat exchanger in place and operated while the heat exchanger is on line.

Abstract: A heat exchanger comprises a plurality of heat exchange tubes inserted into a cleaning device. The cleaning device has the effect of movably scraping the dirt or dust accumulated in an outer side of each heat exchange tube, and a watering device is provided for spraying water to lower the temperature of the heat exchange tubes and to clean the heat exchange tubes. The cleaning device cooperates with the watering device to scrap the dirt or dust accumulated in the heat exchange tubes, clean and lower the temperature of the heat exchange tubes, so as to prevent the dirt or dust from being accumulated in the heat exchange tubes, improve the radiating effect of the heat exchange tubes and save the energy.

Abstract: A curved scraper blade for a scraped-surface heat exchanger pivots about an axis off the centerline of the blade. The profile of the blade is chosen to provide a low initial scrape angle and to change gradually if at all as the blade wears away in service. The off-center pivot placement allows scraped material to flow between the blade and the drive shaft. Several materials are suitable for the blade, including PEEK thermoplastic.

Abstract: Anatase titanium dioxide pigment calcined to a crush strength and density meeting the requirements for an acceptable scour medium is effectively utilized as a scour medium in the chloride process for producing rutile titanium dioxide. The calcining process converts a portion of the anatase pigment to rutile. This calcined anatase can, consequently, be utilized as a scour medium in the chloride process for producing rutile titanium dioxide. The calcined anatase is not a contaminant to the process for producing rutile titanium dioxide. Thus, relatively inexpensive anatase can be converted into a rutile scour medium that can be processed into pigment.
