flue gas exchanger

A flue gas exchanger is a preheating system used, for example, in boilers where exhaust gases are used to increase the temperature of the incoming air stream by reducing the thermal difference. Thus, the same boiler can achieve the same result using less energy.

In these recovery systems we can find different systems, such as air-air, air-gas or air-exhaust fumes systems, and also using other methods, such as air-water or air-steam systems. For example, in wood dryers.

These systems are important to take advantage of all our industrial resources and use surplus industrial energy to reduce our consumption and be more responsible for the environment.

At Boixac Tech we have air-to-air exchangers that can work with high temperatures, high pressures, dusty and corrosive environments.

Heat exchangers in the energy industry

ENERGY INDUSTRY HEAT EXCHANGERS FOR ENERGY OPTIMIZATION Heat exchangers are a very important product in the optimization of energy transformation processes, whether in thermal power plants, nuclear power plants or hydroelectric power plants, among others. Let’s dive deeper into the uniqueness of each of these systems below: 1. In thermal power plants, heat exchangers are used to transfer heat generated by fossil fuels such as coal, oil or gas to a fluid such as superheated water or steam. This fluid reaches high pressures and drives a turbine that generates electricity. As the fluid drives the turbine, it cools and we condense it using a new heat exchanger we call a condenser. Once condensed, we reuse the fluid to heat it with fossil combustion and generate energy again. In thermal power plants we could find cogeneration plants which, in addition to producing heat, generate electricity, as well as trigeneration plants, which, in addition to producing heat and electricity, generate refrigeration energy, which means greater energy efficiency and sustainability. 2. In nuclear power plants, heat exchangers are essential to control the temperature of the reactor with the help of a coolant. The heat transfer fluid absorbs the heat and transmits it to a steam generator which will convert the energy into electricity. This coolant, once cooled, will return to the start to start the process over. Beyond this aspect of operation, heat exchangers are also used as a preventive measure in diesel engines with the aim of controlling a possible electrical shutdown. There are many other models of energy generation, all with very particular singularities that we will analyze in other articles. Beyond the explanatory brushstrokes we have made, all projects require in-depth analysis and a highly experienced professional team. If you have any needs, contact us, we are at your disposal.

ECONOMIZER GREENHOUSES AND FARMS Heat recuperators are important in many fields and one of them are greenhouses and farms. In this area we work in two main blocks: 1. The first block refers to the treatment of water for the hydroponic growth of tomatoes, lettuce, peppers, strawberries, etc. One solution is to heat the water in the channel before it is distributed to the plants through finned tubes. These heat exchange systems can be supplied with spiral fins or continuous fins in the same direction as the tubes. This technology homogenizes the heat in all plants and facilitates its control. Another solution is heating the air through upper ducts where BOIXAC provides the finned exchangers that heat the air in the greenhouses and farms. These exchangers can include multiple accessories such as fans and controls. 2. The second block refers to the technology that enriches the environment and thus increase photosynthetic activity. We do this by reusing the excess heat from the exhaust gases through the ECOND, AIRY or GASY heat recuperators. These heat exchange equipment are selected based on the primary and secondary fluids, in addition, the materials are also chosen according to the specific needs of each installation.
