摘要： A tube bundle heat exchanger having an additional tube bottom with insertion tubes arranged in the inlet chamber upon the inlet side of the hot gases for the tubes located between the tube bottoms of the tube bundle. The additional tube bottom is arranged in such a way that both tube bottoms in the inlet chamber define another inlet chamber for colder, slag-free gases, which inlet chamber is accessible through an inlet in the shell of the tube bundle heat exchanger. The insertion tubes project far into, but not to the end of, the tubes of the tube bundle. The insertion tubes, with the outer tubes, form relatively narrow annular spaces suitable for generating high discharge speed. Four spiral formed strips respectively located in the annular spaces impart a twist to the gas flow discharging from the annular spaces to assure that gas discharging between the insertion tubes and the tubes of the tube bundle remain in flowing contact along the inner walls of the tubes. Slag-containing gas coming from a coal gasificatin reactor flows through an inlet into the inlet chamber of the tube bundle heat exchanger and is cooled off in three regions during flowing through the tube bundle heat exchanger whereby temperatures of the cooling-off gas are maintained in such a manner that slag is precluded from depositing upon the heat transfer surfaces while the gas is cooling off.

摘要： Device for cooling gases deriving from ammonia synthesis. The device consists of pipes accommodated in an interior space. The space is subjected to a heat-absorption medium and surrounded by a cylindrical mantle. The pipes are secured in a pipe floor and communicate with a gas-intake chamber and a gas-outlet chamber. When an ammonia-production plant has several reactors, a single gas-cooling device has up to now been associated with each. The new device is intended to decrease the engineering expenses involved in cooling the gases in such plants. A gas-intake chamber and a gas-outlet chamber is positioned at each of the two opposite ends of the jacket. Straight pipes are associated with each chamber. The pipes are adjacent and the gas flows through them in opposite directions.

摘要： A heat exchanger for cooling superheated steam with water, yielding saturated steam. The heat exchanger consists of U-shaped pipes (4) that the superheated steam flows through. The pipes are accommodated in a jacket (1) provided with intakes (10 & 11) and outlets (12 & 13) for the evaporating water. The pipes have their ends secured in a slab of tubes. The slab demarcates a chamber that is separated by a partition into an intake compartment (17) with an intake (14) and an outlet compartment (18) with an outlet (15). To improve the generic heat exchanger, part of the partition (16) has been removed and replaced with a rotating plate (19), the plate is attached to a rotating disk (21) that is perpendicular to the plate and has an opening (22) through it and a solid section on each side of the plate, the rotating disk faces a stationary disk (23) secured to the inner surface of the chamber (7) away from and parallel with the slab (5) and provided with openings (24) and solid sections that are similar to those in the rotating disk, and the side of the slab that faces away from the chamber rests on a thicker support (8).

摘要： A tube-bundle heat exchanger for cooling a medium having a high inlet temperature. The heat exchanger has an inlet tube bottom and an outlet tube bottom, in which are fastened the ends of tubes which connect the bottoms and through which the medium of high inlet temperature flows. An intermediate tube bottom, having insert tubes arranged concentrically in the tubes, is located in the inlet chamber, with these insert tubes projecting out on both sides from the tubes and forming annular spaces therewith. Toward the inlet chamber, the annular spaces open into an intermediate chamber limited by the inlet tube bottom and the intermediate tube bottom; in the opposite direction, the annular spaces open into a deflecting or reversing chamber sealingly covering the insert tubes.

摘要： An overpressure-control valve has a valve housing formed with a front output chamber, a back intake chamber adjacent and back of the output chamber, and a valve seat lying between the chambers. A valve body can move in the housing forward toward the valve seat into a closing position on the seat and blocking flow between the chambers and backward from the valve seat and into an open position permitting flow between the chambers. This body has at least one forwardly directed face and at least one backwardly directed face exposed in the chambers. The effective surface area of the forwardly directed face is greater than that of the backwardly directed face. A spring urges the valve forward into the open position with a predetermined generally constant biasing force so that the valve body moves back against the spring into the closed position when the backwardly effective pressure on the forward face overcomes both the force of the spring and the pressure on the back face.

摘要： A flow-control valve assembly comprises a housing formed with a valve chamber, an inlet port and an outlet port both opening into the valve chamber, a valve seat at one of the ports, and a control chamber. A valve body is displaceable in the valve chamber between a closed end position engaging the seat and blocking flow between the ports and an open end position clear of the seat and permitting flow between the ports through the chamber. This valve body has a valve face exposed to the pressure at the inlet seat in the closed position. A control body in the control chamber has a control face and an oppositely directed counterpressure face. This control body subdivides the control chamber into a control compartment at the control face and a counterpressure compartment at the counterpressure face. The counterpressure face is of greater effective surface area than the valve face. A link interconnects the control and valve bodies for joint movement for increasing the volume of one of the compartments while decreasing that of the other compartment as the valve body moves from the open to the closed position and for decreasing the volume of the other compartment while increasing that of the one compartment as the valve body moves from the closed to the open position.

摘要： A heat exchanger for cooling hot reaction gas with a coolant. The exchanger rests on a gas-supply chamber (4) and has gas pipes (8). The pipes extend individually out of a wall (1) that surrounds the pipes and are accommodated in a pipe-slab floor (6) between the wall and the chamber. The pipes extend through bores (20) in the floor leaving an annular gap (21). At least one coolant-supply line (9) terminates on the side of the floor facing away from where the gas enters. Chambers (12) demarcated by a flat bottom (15), by a partition (13) that parallels the pipes, and by part of a wall-mounted ring (14) are accommodated in the half of the floor facing the side where the gas enters. The chambers communicate with a common coolant supply. One or more gas pipes (8) extends through every such chamber. The ring is positioned at the edge of the floor and surrounds all the chambers. The floor comprises a thinner section (18) that is cooled by the coolant and constituted by the bottoms of all the chambers and a thicker and rigid section (19) that the thinner section rests on by way of the partitions.

摘要： A nested-tube heat exchanger with tubes (1) secured at each end in tube plates (3 & 4) for transferring heat between a hot gas that flows through the tubes (1) and a liquid or vaporous contact that flows around the pipes. The tube plates are secured to a jacket (2) that surrounds the nest of tubes. One of the tube plates has parallel cooling channels (7) in the half that faces away from the jacket with coolant flowing through the cooling channels. The tube plate has bores (15) that open into the jacket, communicate with the cooling channels, and concentrically surround the tubes. The tube plate that has the cooling channels is at the gas-intake end of the heat exchanger. The tubes in each row extend through cooling channels. The base (12) of the cooling channels on the side that is impacted by the gas is uniformly thick.

摘要： A heat exchanger is especially for cooling cracked gases with boiling water. It consists of pipes (1) that the gas to be cooled flows through and that are surrounded by a cooling jacket with a coolant flowing through it. The end of each pipe that faces the gas intake is surrounded by a sleeve. The coolant flows through the sleeve. The volume of coolant flowing through the sleeve is less than the heat supplied from the gas being cooled. (FIG. 1).
