Refinery Heat Recovery Industrial Coil Heat Exchanger

Refinery Heat Recovery Industrial Coil Heat Exchanger

The Industrial Coil Heat Exchanger for Heat Recovery in Waste Plants is a device used in waste treatment plants to recover the heat generated by waste incineration or other thermal processes.

Working Principle

Heat transfer: there is a coil inside the heat exchanger, the hot medium (such as high temperature flue gas or hot water produced by waste incineration) flows inside the coil, and the cold medium (such as air, water or other fluids that need to be heated) flows outside the coil. Due to the temperature difference between the two media, heat is transferred from the hot medium through the coil wall to the cold medium to achieve heat exchange.

Reinforcement of heat transfer method: the coil usually adopts special design, such as spiral, finned and other structures, in order to increase the heat transfer area and perturbation of the fluid, to improve the efficiency of heat transfer. For example, finned coiler in the outer surface of the coiler to increase the fins, increasing the contact area with the cold medium, so that the heat transfer is more rapid; spiral coiler can make the heat medium in the tube to form turbulence, to enhance the heat transfer effect .

Structural characteristics

Coil structure: metal tube (such as steel, copper or stainless steel tube) bent into a spiral or other shapes of the coil, has a high heat transfer efficiency and compact structure, can be achieved in a smaller space to achieve a larger area of heat transfer.

Shell and material: the shell is generally made of carbon steel, stainless steel and other materials, with good pressure and corrosion resistance, able to withstand the harsh working environment of the waste plant. According to different application scenarios and media requirements, choose the right material to ensure the service life and performance of the equipment.

Connection: The connection between coiler and shell, inlet and outlet piping is usually welded, flanged or threaded, etc., to ensure a firm connection and good sealing to prevent media leakage.

Advantage

Efficient heat recovery: It can effectively recover heat from high temperature flue gas, waste water or other heat sources in the waste treatment process, improve energy utilisation and reduce energy consumption and operating costs.

Adaptable to harsh environments: Waste plants often operate in harsh environments with high temperatures, corrosive gases and dust. The heat recovery industrial coil heat exchanger has good resistance to high temperature, corrosion and abrasion, and is able to operate stably in such harsh environments.

Customised design: The design can be customised according to the specific process requirements and heat source characteristics of the waste plant to meet different heat recovery needs, such as recovering heat from different temperature ranges, handling different flow rates of media, etc.

Compact structure: occupies little space, easy to install and maintain, can be flexibly arranged in the limited space of the waste plant, and also reduces the installation and maintenance costs of the equipment.

Application Scenarios

Waste incineration power generation: In waste incineration power plants, it is used to recover the heat in the high-temperature flue gas discharged from the incinerator, generate steam to drive the turbine to generate electricity, and improve the efficiency of power generation.

Waste pyrolysis: In waste pyrolysis process, the heat exchanger can recover the heat in the high temperature gas or liquid generated by pyrolysis, which can be used to preheat the waste entering the pyrolysis furnace or other process requirements, reducing energy consumption.

Anaerobic fermentation of waste: In the process of anaerobic fermentation of waste to produce biogas, a certain amount of heat is released. Heat recovery industrial coil heat exchangers can be used to recover this heat and use it to heat the fermentation material or maintain the temperature of the fermenter to improve fermentation efficiency.

Other heat recovery applications: It can also be used to recover the waste heat from other thermal processes in the waste plant, such as waste drying, waste melting, etc., to achieve the comprehensive use of energy.
