Many heat exchangers are U-shaped to maximize tube surface and heat exchange in a confined room. A u-tube heat exchanger or let’s say a u-tube configuration also makes it simple to enter the package.
There are three primary classifications of heat exchangers according to their flow arrangement. In parallel-flow heat exchangers, the two fluids enter the exchanger at the same end, and travel in parallel to one another to the other side.
One of the most significant advantages of the straight tube heat exchanger is its simplicity. Straight tube exchanger is also common because of its flexibility. Straight tube exchanger allows for pure countercurrent flow within the exchanger without the need for a second one to be connected in series to the first.
About System Boiler
In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be the combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide-rich off-gasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission.
Several factors should be taken into account when choosing the correct boiler. If you’re replacing an old boiler in your new home or buying one for the first time, the following considerations will help you choose the best boiler for your needs. It’s important to remember that only a professional and knowledgeable gas engineer will advise you on the appropriate boiler for your home and requirements.
