kettle type heat exchange
kettle-type reboiler is consists of tube bundles, the tube bundles are supported by a support plates. The structure of tubes can be either straight tubes or U-shaped tubes. The straight tubes are more versatile they make the cleaning easier. The U-shaped tubes have an advantage that they allow for thermal expansion without putting the rest of the exchanger at risk.
The defining feature of the Kettle type reboiler is that the tube bundles are placed inside a large specifically designed horizontal shell known as TEMA K-shell. The weir is provided inside the shell in order to control the level of the liquid. The vertical length of the weir dictates what quantity of liquid will be retained in the shell. It is important because the tube bundle must compulsorily be immersed inside this quantity of liquid at all times during the runtime of the process.
The difference with other heat exchangers in structure is that the upper part of the shell is provided with an evaporation space, the size of the evaporation space is determined by the gas production and the required vapor quality.
Applications:
Oil refining, petrochemical , natural gas chemical, coal chemical, shale oil , synthetic resin and plastic, rubber, chemical fiber, chemical, pharmaceutical, daily chemical, chemical additives , metallurgical , power , light, food and other industries of material preheating, heating, cooling, distillation, distillation, concentration, material and the heat back Collection, tail gas treatment and other processes industrial.
The equipment material can choose all kinds of stainless steel and other metal materials, the heat exchange tube adopts special seamless steel tube for heat exchanger, and the heat exchange area can be customized as required. The tubesheet and baffle are punched by nc drilling to ensure the accuracy of the hole. Tube plate and heat exchange tube welding joint adopts automatic argon arc welding, hydraulic expansion joint, it's high qiality,safety reliable and durable.
Advantage:
- Low circulation rates, horizontal configuration and all vapour return flow make kettle type reboiler relatively insensitive to system hydraulics, as a result they tend to be reliable even at very low (vacuum) or high (near critical) pressures.
- Kettle type reboilers can operate efficiently with small temperature driving forces, as high heat fluxes can be obtained by increasing the tube pitch.
