Method for operating a steam generation system
A method is disclosed for anticipating operation characteristics of a steam generation system, the steam generation system comprising at least one boiler. The method comprises conducting a fuel analysis of a solid fuel and anticipating the at least one operation characteristic of the steam generation system at the time when a specific partial quantity of solid fuel is combusted in the furnace of a boiler of the steam generation system, and further determining at least one adapted setpoint of at least one operation parameter of the steam generation system dependent upon the fuel composition of any specific solid fuel partial quantity so as to counteract and/or remedy changes of the at least one operation characteristic which are caused by the fuel composition of the specific solid fuel partial quantity. The method may be employed to improve operation of a steam generating system when the fuel composition varies.
Method of installing liner assembly for pipeline repair or reinforcement, and liner assembly and steam generator for same
A method of installing a liner assembly for pipeline repair or reinforcement includes: pulling a prepared liner assembly into position in the pipeline, the liner assembly including an outer tubular liner and an inner inflatable bladder positioned longitudinally within the tubular liner, the tubular liner being wetted with a curable compound; introducing fluid into the inflatable bladder so that the inflatable bladder expands to bring the tubular liner into firm contact with an interior surface of the pipeline; flowing the fluid continuously through the bladder and discharging the fluid into the pipeline, while maintaining the liner assembly in an inflated condition for a time period sufficient for the tubular liner to cure; and deflating the inflatable bladder and retrieving at least a portion of the liner assembly from the pipeline.
Penetration seal apparatus and method
A tubular base plate assembly has a lower surface connected to a heating system component and an upper surface. A tubular seal plate assembly is positioned above the base plate assembly upper surface having a mating surface facing the base plate assembly upper surface with a plurality of grooves therein. Sealing material is provided within the grooves. A tubular hub assembly is positioned above the seal plate assembly. A plurality of fasteners connects the seal plate assembly to the hub. A plurality of external brackets connects the seal plate assembly to the base plate assembly to secure the seal plate assembly. The sealing material forms a first gasket between the seal plate assembly and the base plate assembly. Each of the external brackets is joined to the tubular base plate assembly, so that the external brackets and the tubular base plate assembly are integral.
TUBE LEAK DETECTION DEVICE AND TUBE LEAK DETECTION METHOD
A tube leak detection device for detecting leak of at least one tube of a heat exchanger which increases a temperature of a liquid by heat exchange between the liquid flowing inside the at least one tube and a fluid flowing outside the at least one tube includes: an inlet opening-and-closing valve and an outlet opening-and-closing valve disposed at an inlet end and an outlet end of the at least one tube, respectively; and a pressure detection member for detecting a pressure inside the at least one tube between the inlet opening-and-closing valve and the outlet opening-and-closing valve.
Furnace wall, gasification unit and integrated gasification combined cycle, and method of manufacturing furnace wall
The purpose of the present invention is to provide a furnace wall in which a throat section with a smaller channel diameter than other regions can be formed using all peripheral wall tubes. Provided is a furnace wall comprising: a plurality of peripheral wall tubes (142), which are disposed so as to form a cylindrical shape when aligned in one direction and through the interior of which cooling water flows; and fins (140) that connect neighboring peripheral wall tubes (142) in an airtight manner. In a throat section in which the diameter of a horizontal cross-section of the cylindrical shape is reduced in comparison to other regions, the peripheral wall tubes (142) are disposed so as to be in mutual contact and the fins (140) are disposed on the inner circumferential sides of the cylindrical shapes.
Compact fluid heating system with high bulk heat flux using elevated heat exchanger pressure drop
A fluid heating system for heating a production fluid using a thermal transfer fluid, the production fluid being contained in a vessel includes an electric blower configured to receive ambient air and electrical input power and to provide output source air, a combustion system configured to receive the source air from the electric blower and to receive fuel and to provide the thermal transfer fluid, a heat exchanger configured to receive the thermal transfer fluid from the combustion system and configured to be in thermal communication with the production fluid to provide convective heat exchange from the thermal transfer fluid to the production fluid, and to provide output exhaust gas, and wherein the electric fan provides a predetermined volume flow rate of the output source air at a predetermined blower efficiency such that the fluid heating system has a Bulk Heat Flux of at least about 14.7 kBTU/Hr/ft.sup.2 and a Pressure Drop of at least about 0.7 psi.
All-condition auxiliary denitration system and operation method thereof
An all-condition auxiliary denitration system and an operation method thereof are provided. The system includes a heat-storage medium heater, a low-temperature reheater, an economizer, and an SCR denitration device which are successively interconnected, and further including a heat-storage medium tank and a heat-storage medium and feedwater heat exchanger. A flow of a cold heat-storage medium entering the heat-storage medium heater is regulated, so that heat absorption of the heat-storage medium is matched with a boiler load. Flows of hot heat-storage medium and feedwater, which enter the heat-storage medium and feedwater heat exchanger, are regulated through a feedwater regulating valve and a hot heat-storage medium outlet regulating valve. A total feedwater flow is regulated with assistance of a bypass feedwater regulating valve, so that a temperature of flue gas entering the SCR denitration device is kept in an optimal operation range under different boiler loads, and denitration efficiency is ensured.
Flash boiler
A flash boiler has a water jacket and a vertically oriented interior passage which includes water tubes or superheating tubes, or both. The interior passage is a hyperboloid surface to induce draft. Water tubes and superheating tubes can be staggered so as to create a helical path for flue gas passing through the boiler. Water tubes and superheating tubes may include, internally or externally or both, heat transfer aids such as pins, fins or vanes, which may also be helices.
Tile assembly for a waterwall panel
An array of tile assemblies is fixedly connected to a common waterwall panel to form a refractory liner for an incinerator. Each tile assembly includes a unitary, clip-type, metallic anchor, which is directly welded to the waterwall panel, and a solid refractory tile slidably connected to the anchor through a dovetail locking mechanism. The rear surface of the refractory tile includes a longitudinal rib from which projects a dovetail pin configured to receive the anchor. The longitudinal rib increases the overall thickness of the refractory tile through the region of interconnection with the anchor. In this manner, the anchor is suitably protected by the refractory tile from intense heat which may otherwise cause mechanical failure in the locking mechanism. Additionally, the solid construction of refractory tile both limits the presence of air gaps within the tile assembly and reduces the likelihood of tile fragmentation or cracking.
COMPACT FLUID HEATING SYSTEM WITH HIGH BULK HEAT FLUX USING ELEVATED HEAT EXCHANGER PRESSURE DROP
