摘要： The disclosure provides an arrangement structure suitable for an inverted pulverized coal boiler with ultra-high steam temperature steam parameters, including a hearth, wherein the hearth is communicated with a middle uplink flue, and the top of the middle uplink flue is communicated with that of a tail downlink flue. In the structure, the hearth is connected with the middle uplink flue by a hearth outlet horizontal flue at the bottom, so that the high-temperature gas is drained to a low elevation and then flows upwards through the middle uplink flue; a final heating surface may be arranged at the low position of the hearth outlet horizontal flue and the middle uplink flue so as to reduce the length of the high-temperature steam pipeline between the final heating surface and the steam turbine, lower the manufacturing cost of the boiler as well as the frication and radiation loss of the pipe.

摘要： A small supercritical once-through steam generator (OTSG) includes a radiant section with a furnace coil, and a convection section downstream of the radiant section that includes a superheater which is fluidically connected to the furnace coil. Optionally, the OTSG is devoid of a steam separator. An economizer can also be included downstream of the superheater. Supercritical steam can be generated using the OTSG, for use, among other things, in enhanced oil recovery applications.

摘要： A method for producing superheater tubes and connecting pipes and assembling superheater tubes inside a steam generator tube wall includes preparing tubes composed of precipitation-hardened nickel-based alloys in a solution-annealed state for the straight tubes, the bends, and the connecting pipes in a workshop and preparing sleeves composed of a material that is not to be heat treated in a shop. The bends and the connecting pipes are manufactured in the workshop using bending tools and then the straight tubes, the bends and the connecting pipes are precipitation hardened in the workshop in a first heating device. The superheater tubes are manufactured in the workshop by connecting the straight tubes and the bends with weld seams, and connecting the sleeves with the connecting pipes with weld seams. The weld seams between straight pipes and bends as well as the weld seams between sleeves and connecting pipes are precipitation hardened in the workshop with a second heating devices. The superheater tubes are connected with the connecting pipes on the assembly site inside the steam generator tube walls with a weld seam and the sleeves are connected with the take-up device with a weld seam. The weld seams are precipitation hardened on the assembly site with third heating devices located proximate to the weld seams.

摘要： The disclosure provides an M-type pulverized coal boiler suitable for ultrahigh steam temperature. The pulverized coal boiler comprises a hearth of which the bottom is provided with a slag hole and a tail downward flue of which the lower part is provided with a flue gas outlet. The pulverized coal boiler further comprises a middle flue communicated between the hearth and the tail downward flue, wherein the middle flue comprises an upward flue and a hearth outlet downward flue of which the bottoms are mutually communicated and the upper ends are respectively communicated with the upper end of the hearth and the upper end of the tail downward flue to form a U-shaped circulation channel. In the pulverized coal boiler provided by the disclosure, the middle flue which extends downwards and can make flue gas flow along the U-shaped circulation channel is arranged between the outlet of the hearth and the tail downward flue, so that high-temperature flue gas from the hearth can be introduced into a position with low elevation through the downward flue, and final-stage convection heating surfaces (such as a high-temperature superheater and a high-temperature reheater) can be arranged at positions with low height, and the length of ultrahigh-temperature steam pipelines between the high-temperature superheater and a steam turbine, and between the high-temperature reheater and the steam turbine can be greatly reduced. Therefore, the manufacturing cost of a boiler unit is obviously reduced.

摘要： An evaporator including a lower drum, an upper drum, and at least one tube extending between the lower drum and the upper drum. The plurality of tubes have fluid passageways therein extending from the lower drum to the upper drum. A duct is provided having a heating gas passageway provided therein. The at least one tube extends through the heating gas passageway. The fluid passageways define an overall flow path from the lower drum to the upper drum extending in a direction substantially counter-current to an overall flow path defined by the heating gas passageway extending from a gas inlet of the heating gas passageway to a gas outlet thereof.
