Principle of heat transfer
Heat transfer in professional printed circuit heat exchanger is a process by which the internal energy source from one substance transfers to another. Thermodynamics is the investigation and study of heat transfer and other changes causes by heat transfer.
An understanding of heat transfer is crucial for the study and analysis of a thermodynamic process, such as those that take place in heat engines and heat pumps.
What is heat transfer?
Heat transfer is the process of exchanging heat between two natures and the environment with different temperatures through a separating wall. This is a common case of complex heat exchangers in practice.
Heat exchange between nature and the high-temperature environment with the baffle plane accomplish essentially by convection or convection and radiation.
Conduction of heat through the baffle plane
Heat exchange between the baffle plane and the low-temperature natural environment basically implement by convection.
Depending on the type of baffle plane, there are heat transfer forms such as: heat transfer through flat wall, cylindrical wall or winged wall.
Heat transfer equipment
A heat transfer device, also called a heat exchanger, is a device uses to conduct heat exchange between heat carriers of different temperatures. Examples: condensers or condensers, calorifes uses in drying equipment, water heaters and air dryers in power plants.
Classification of professional printed circuit heat exchanger
Heat exchanger is widely using in engineering, its efficiency and structure can completely be very different but in principle of operation, we can all completely divide heat exchanger into 3 types:
What is heating?
In recent years, heaters have been widely using for indirect process heating. This appliance uses petroleum-basic liquid fuel as a heat transfer medium. These heaters distribute a completely maintainable temperature to the appliance in use.
The oil-fired heater consists of a twin tube, tertiary structure and fit with a network of pressure nozzle systems. Recreational active fluid, as a heat carrier, heat in the dryer and recirculated in the user equipment.
Therefore, the heat transfer fluid for the process passes through the professional printed circuit heat exchanger and the fluid returns to the dryer. The flow of the fluid at the end use control and regulate by pneumatic control and regulation valves, based on the management and operating temperatures.
People control and adjust the recreational performance of the combustion chamber depending on the heat use needs of the material to be heated.
Advantages of heating equipment
The heater operates in a closed cycle with minimal loss compared to steam boilers, automatic control setting, flexible operation, good thermal efficiency. This equipment system does not damage and losses due to blow down discharge of condensate and steam expansion.
The economy of the professional printed circuit heat exchanger depends on the specific application. Coal fired heaters are efficient in the 55% – 65% range and it is comparable to most boilers.
What is superheated steam?
Superheated steam is a form of vapor at a temperature higher than the boiling point of the source liquid. The point of vaporization, at a certain pressure is important. It's a relative state called saturation.
Explain the characteristics and effects of superheated steam (for example for power generation). It includes explanations of thermodynamic processes, superheated steam tables and Mollier (HS) diagrams.
Most importantly, if the saturated steam generated in the boiler of professional printed circuit heat exchanger is in contact with a higher temperature plane. Its temperature will rise above the evaporator temperature.
The steam is then considered superheated steam by the temperature to which it has heated above the saturation temperature.
Application of superheated steam in printed circuit heat exchanger
Use superheated steam for sterilization
Superheated steam is uses as a disinfectant. However, there are many limitations that this application of superheated steam has not widely used such as:
- The place of use must be close to the place where the superheated steam produces.
- Too high temperature affects the area to disinfect.
- Equipment for storage and distribution at high temperatures and pressures shall provide.
- Using superheated steam to spin turbines to generate electricity
A great application in the thermal power industry
Firstly, superheated steam in professional printed circuit heat exchanger considers a great application in the thermal power service industry. Secondly, the enormous energy source within the superheated steam itself is uses for the kinetic reactions. Thirdly, it undergoes mechanical contraction and expansion that drive turbines and generate electricity in thermal power plants.
Superheated steam is preferred over saturated steam. It can completely release a lot of energy in the same state of steam's temperature and pressure specifications.
Using superheated steam in a steam engine
Superheated steam is widely using in steam locomotives and other steam engines. It proved to be more economical and efficient than saturated steam to drive locomotives.
Because of its high dryness, superheated steam in professional printed circuit heat exchanger. It has less ability to condense inside the locomotive's cylinders reducing the need for periodic drainage.
Using superheated steam in industry
Moreover, superheated steam also has uses for industrial applications. For examples: networks of drying systems for agricultural products, seafood, beer factories, confectionery factories, food factories, etc.
Pressure is an influence force
Pressure (symbol: vector N or F) is the perpendicular force on a face or a designated contact area of the user object bearing the force.
However, it is an influence force acting on a defined plane area of an object. The force is perpendicular to the specified area of the bearing plane. In the general sense, as well as the general concept of force, compressive pressure is a vector quantity.
However, the direction (perpendicular to the bearing plane of professional printed circuit heat exchanger) and the direction (towards the bearing surface) have been established. One can absolutely only talk about the magnitude (intensity).
What is pressure in printed circuit heat exchanger?
In conclusion, Pressure is a quantity calculated as the ratio value of the force applied in a direction perpendicular to a surface to the area of that surface. To put it more simply, pressure is the magnitude of the pressure (force perpendicular to the plane of pressure) per unit area pressed.
