ASME Boiler Gas Cooler Heat Exchanger For Power Plant Carbon / Stainless Steel

ASME Certification Boiler Flue Gas Cooler For Power Plant Carbon/Stainless Steel

Product Description

The mechanism of a refrigeration system, a type of heat exchanger, that converts gases or vapors into liquids and transfers heat from the pipe to the air near the pipe in a rapid manner.The condenser is an exothermic process, so the temperature of the condenser is higher.

A power plant USES many condensers to condense the steam from the turbines.Condensers are used in refrigeration plants to condense refrigerating vapors like ammonia and freon.Condensers are used in the petrochemical industry to condense hydrocarbons and other chemical vapors.In the distillation process, the device that converts vapor into liquid is also called a condenser.All condensers work by taking heat away from gases or vapors

Advantage

In the traditional boiler, after the fuel is burned in the boiler, the smoke exhaust temperature is relatively high, and the water vapor in the flue gas is still in the gaseous state, which will carry a lot of heat.Among all kinds of fossil fuels, natural gas has the highest hydrogen content, and the mass percentage of hydrogen is about 20% to 25%. Therefore, smoke exhaust contains a large amount of water vapor. It is estimated that the heat taken away by the steam generated by burning natural gas of 1 square meter is 4000KJ, which is about 10% of its high calorific value.

Flue gas condensation heat recovery unit, the use of low temperature of the water or air cooling flue gas, flue gas temperature lower, close to the heat transfer surface area, the water vapor in flue gas condensation, at the same time realize the flue gas sensible heat release of latent heat release, and water vapor condensation and heat exchanger heat absorption by water or air heating, heat recovery, improving heat efficiency.

Theory

The gas passes through a long tube (usually coiled into a solenoid), allowing heat to escape into the air around it.In order to improve the efficiency of the condenser, heat sinks with excellent heat conduction performance are often added to the pipes to increase the heat dissipation area to accelerate the heat dissipation, and to accelerate the air convection through the fan to take away the heat.

The refrigerating principle of the general refrigerating machine is that the compressor compresses the working medium from the low temperature and low pressure gas into the high temperature and high pressure gas, and then condenses into the medium temperature and high pressure liquid through the condenser, after throttling through the throttle valve, it becomes the low temperature and low pressure liquid.The liquid working medium of low temperature and low pressure is fed into the evaporator, which absorbs heat and evaporates into the steam of low temperature and low pressure, and then is sent into the compressor to complete the refrigeration cycle.

Single-stage steam compression refrigeration system is composed of four basic components of refrigeration compressor, condenser, throttle valve and evaporator, which are connected successively by pipelines to form a closed system. Refrigerant circulates continuously in the system, changes in state occur, and exchanges heat with the outside world.
