Indirect heating by conduction uses drastically less energy than other conventional direct heating equipment, such as fluid bed heaters or rotary heating equipment. Recover and reuse waste energy Indirect plate heating technology makes it possible to capture and use low-grade heat from elsewhere in your facility for heating bulk solids
Nov 09, 2020 · The most common type of indirect heat exchange is performed with a shell-and-tube heat exchanger, which uses a bundle of tubes housed within a cylindrical outer shell. One of the fluids flows through the long surface area of the tubes, making thermal contact with
Heat Exchangers:How They Work, and Why They Are NeededJul 12, 2014 · Typically indirect contact heat exchangers will keep the hot and cold fluids in different sets of pipes and instead rely on radiant energy and convection to exchange the heat. This is commonly done to prevent contamination or pollution of one fluid by the other. The Physical State of the Fluids
Heat exchangers are used in heating systems to separate two media, while at the same time transferring heat from one to the other. An example of this type of application is a heating system with indirect district heating. Here, a heat exchanger is fitted directly after the supply pipe to the building. The heat is transferred from the district
Indirect Heating System - an overview ScienceDirect TopicsFor the case of indirect heating systems, heat exchanger is used where steam is cooled and condensed in the tube and the heated tube delivers the heat to the liquids and gases. There are many advantages for stream process heating systems and it could be used for the varieties of by-product fuels  .
Sigma Thermal offers a unique option for indirect steam generation that utilizes high-temperature hot oil and a customized heat exchanger . In facilities that have several high-temperature users and that plan to use a hot oil system in addition to steam, the need for a separate fuel-fired boiler can be eliminated.
Indirect vs. Direct:The Heat Transfer Method Does Affect Mar 01, 1999 · Most applications employ steam as an indirect source, using either a heat exchanger to transfer heat to a gas carrier or a jacketed vessel or drum to heat a surface. It also is used as a direct heat source to achieve effective drying. The amount of energy that can be carried by steam is related to the pressure at which the steam is delivered.
This indirect heating of the process air is typically achieved by adding a gas-to-gas Industrial Heat Exchanger at the discharge of the air heater. The industrial heat exchanger transfers the available heat contained in the air heater hot products of combustion to a process air stream, while keeping the process air stream segregated from the air heater products of combustion.
Thermal Processing, Indirect Heating & Cooling Technology The BCR ELECTRIC-SCRU TM is an electrically heated screw-type heat exchanger for continuous thermal processing of a wide range of materials. The ELECTRIC-SCRU TM incorporates multiple heating zones with the unique advantage of being able to provide controlled heating at different process stages within the same unit. Feedstocks can be heated to over 1200F while under a sub-ambient vacuum or
Oct 02, 2020 · INDIRECT HEATING TECHNOLOGY. In the last 25 years, a more efficient and cost effective method has been introduced, using indirect heat transfer to heat free flowing bulk solids. A series of vertically stacked modules filled with hollow, stainless steel plates comprise an indirect heat exchanger. This unit uses a counter-current flow of heating water or fluid running through the hollow
