A PRE-HEAT HEAT EXCHANGER WITH MULTI-WALL WHICH LEADS THE
WATER TECHNICAL FIELD
The invention relates to a heat exchanger which increases the contact surface of the water with the flame and flue gas during the water heating process in boilers and the like heat exchangers and provides both energy saving and minimization of flue gas heat by providing preheating with at least two-walled structure.
PRIOR ART
Boilers used in indoor heating work on the principle that the water circulating around the combustion chamber is heated with the heat generated in the combustion chamber by burning the air-gas mixture.
In the prior art, heat exchangers in the form of spiral tubes or in the form of plates are used. Science and industry, which works to make human life comfortable with limited energy resources, continues to work intensively on efficient heating of water and minimizing the damages of the flue gas to the environment.
The temperature of the gases exit from the burner during operation of the boiler has an average value of 950 to 1 ,000 ° C. In order to transfer the temperature to cold water efficiently with the help of heat exchanger, the contact surface must be wide. In addition, unburned gas residues and high temperature release of flue gas into the atmosphere are a threat to environmental health.
In the prior art applications, the heating of the water passing through the pipe or plate is heated as a result of the heating of the pipe or plate by single-wall water channels arranged circularly and with spaces between the edges of the combustion chamber. In addition, a set is placed between the combustion chamber and the flue outlet so that the direct flow of the flue gas to the flue is prevented and the energy of the flue gas is reduced by providing more contact with the plate or pipes. The limited contact surface reduces the expected yield.
Another factor affecting the efficiency is that the burner of the boiler ensures that the gas in the combustion chamber is burned as full as possible. This makes the burner cover, where the air-gas mixture is made, an important part of the system. Here, it is necessary to isolate the noise generated by the fan in order to provide gas and air mixture. However, the failure to achieve this is one of the technical problems.
Combustion of gas and air in the combustion chamber of the boiler burner generates a high temperature inside. Even a heat insulating material is placed on the inside of the burner cover, reflection of the heat occurred inside to the burner cover cannot be prevented and due to this situation, it can reach a heat level that may cause harm to human health on a contact. The fan must operate in order to provide gas and air mixture. Noise pollution occurs during fan operation. In addition, different types of silencers are used to minimize this noise pollution.
BRIEF DESCRIPTION OF THE INVENTION
The invention is a heating system comprises a heat exchanger with at least two walls, one in the outer section and one in the inner section, which gradually provides the heating of the water and provides homogeneous efficient heating by distributing the heat of the gas, the flue gas and the heat of the heated water in a balanced manner between the plates and between the walls with maximum exchange surface. The invention further comprises a burner cover which sends a mixture of hot air and gas into the burner by making use of the heat generated on the burner cover and minimizes the noise level and provides the mixture of air and gas.
The sheets forming the heat exchanger system is in a two-part form and comprise at least two walls, one in the outer section and one in the inner section, which allow the heating of the water gradually. Heating is provided by circulating water gradually on these walls. In the same area, water is provided to come into contact with more surfaces of the plate, thus providing maximum interaction with the heat energy in the environment. In addition, homogeneous heating is provided by means of the heat transfer between liquids thanks to the contact surface between the wall. The instantaneous water heating capacity can be increased at the rate of need with the cycle formed by grouping the sheets having the same walls and providing the water cycle.
Each sheet is in a two-part form and has a different wall structure thus provides ease of service and installation. The problem that will occur in one of the parts of the sheets eliminates the necessity of replacing the whole of the heat exchanger and the repair process is economized and becomes easier by only replacing the relevant part of the sheets. In addition, all surfaces on which the burned gas circulates are provided to be in contact with water. In this process, all the energy of the burned air gas mixture is taken and efficient heating is provided, while the temperature of the flue gas is minimized.
The system comprises a combustion chamber (inferno) formed by combining the sheets, the condensate section, the burner and the burner cover which allow the transport of gas mixture to the combustion chamber. The condensation section at the end of the combustion chamber, which is formed in at least two stages, contains a set between the combustion chamber according to the number of stages. By means of these sets, the circulation of the air - gas mixture burned by the burner in the combustion chamber between the plates and the contact surface of the slices are maximized. In the condensation section, the temperature of the flue gas is minimized. Thanks to the at least two-stage set created in this stage, the flue gas performs its pre-heating function by contacting all the plates in the stages and transferring its energy to the cold water. As the heating capacity is increased, the amount of flue gas and temperature will increase and the number of stages is increased at that rate to maintain efficiency.

In the final stage of preheating, after the water circulates in the inner wall (3.1.1 ) of the H 1 H2 sheet set (4.3), it passes through the water direction between sheets (3.1.4) outlet to the water direction inside the sheets (3.1.5) at the end of the inner wall to the outer wall (3.1.2) of the H 1 H2 sheet set (4.3), then to the outer wall (3.1.2) of the F1 F2 sheet set (4.4). The H 1 H2 sheet set (4.3) serves as the transition set between condensation and heating. After the preheated water has circulated through the outer wall (3.1.2) of the F1 F2 sheet set (4.4) and E1 E2 sheet set (4.6), the water in the E1 E2 sheet set (4.6) is passed to the collector (3.1.3) through the water direction collector (3.1.9). During the preheating process, cold water circulates the inner and outer walls of all the sheet sets in the condensation unit (4) first as the inner wall and then the outer wall. In this way, the flue gas formed by the mixture of air and gas burned by the burner (2) transmits its energy to the cold water in the inner and outer walls by contacting the surface of all the sheet sets in the condensation unit (4) by means of the outer flame direction (4.5) set. Thus, while the flue gas heat released to nature is reduced to a minimum, preheating is performed before the cold water is sent to the heating unit (3) and the amount of energy to be spent for heating is reduced. Thanks to the contact surface between the inner wall and the outer wall, it is a homogeneously heated water by transferring the heat of the circulating water in the walls during the preheating process. At the same time, by changing the direction and order of these sheets, water flow volume and flow rate are increased by entering and circulating water from two or more sheets simultaneously. For this reason, the water flow volume and flow rate required for higher calories are provided.
The preheated water is transferred from the collector (3.1.3) through the water direction collector (3.1.9) to the outer wall (3.1.2) of the A1A2 sheet set (3.2). After the water to be heated circulates in the outer wall (3.1.2) of the A1 A2 sheet set (3.2), it comes to the outer wall (3.1.2) of the B1 B2 sheet set (3.3) from the water direction between sheets (3.1.4) outlet. After circulation is provided in the outer wall (3.1.2) of the B1 B2 sheet set (3.3), water is transferred from the water direction between sheets (3.1.4) outlet to the outer wall (3.1.2) of the C1A2 sheet set (3.4). After the circulation in here is completed, comes to the outer wall (3.1.2) of the B1 B2 sheet set (3.3) through the water direction between sheets (3.1.4) outlet. The group made of C1 A2 sheet set (3.4) and B1 B2 sheet set (3.3) is connected in series and the amount of water to be heated instantaneously in the circulation is increased. After the circulation is completed, the water between the sheets is transferred from the water direction between sheets (3.1.4) outlet to the following D1 D2 sheet set (3.5). After circulation is provided in the outer wall (3.1.2) of the D1 D2 sheet set (3.5), the water passes through the water direction inside the sheets (3.1.5) located at the end of the outer wall to the inner wall (3.1.1 ) of the D1 D2 sheet set (3.5). After the water is circulated in the inner wall (3.1.1 ) of the D1 D2 sheet set (3.5), the water passes through the inner walls (3.1.1 ) of the group connected in series formed by the B1 B2 sheet set (3.3), C1A2 sheet set (3.4) respectively and comes to the inner wall (3.1.1 ) of the A1A2 sheet set (3.2). After the heating process is completed, the water is circulated through the inner wall (3.1.1 ) of the A1A2 sheet set (3.2) and is fed to the system through the plumbing hot water outlet (3.1.8) through the water direction collector (3.1.9). As the inner walls are the closest to the flame, the heating is completed by this circulation. In the heating unit (3), the flame formed by burning the air gas mixture by the burner (2) in the combustion chamber (inferno), which is formed by the A1A2 sheet set (3.2), B1 B2 sheet set (3.3), C1A2 sheet set (3.4), D1 D2 sheet set (3.5), is held in the heating section by at least one insulated inner flame direction set (3.6). Thus, the flame circulating between the sheet sets transfers all its energy to the preheated water in the inner and outer walls by contacting the surfaces of the all sheet sets. Thanks to the contact surface between the inner wall and the outer wall, homogeneous heating is provided by transferring the heat of the circulating water to each other during the pre-heating process. Thus, it is ensured that water is supplied to the system at constant temperature and instantaneous temperature changes are minimized.
The flame required for the heating of the water is formed by firing the air-gas mixture provided by the burner cover (1 ) in the combustion chamber of the burner (2) by means of the sparking plug (1.6). The heat generated by the ignition of the air and gas mixture reaches the cover despite the thermal insulation. With the help of the heat transferred to the cover, the cold air entering through the silencer manifold (1.1 ) is heated while passing through the airway (1.8) while the cover is cooled. The cooling of the cover prevents burn-related injuries during contact with the boiler. The heated air increases the heating efficiency as it is not transmitted cold to the combustion chamber together with the gas. The flame formed in the combustion chamber circulates by contacting the outer surfaces of all the sheet sets in the heating unit with the insulated inner flame direction set (3.6). The externally directed flame is guided between the sheet set H1 H2 and D1 D2 by means of the outer flame direction (4.5). The insulated inner flame direction set (3.6), located in the middle of the F1 F2 sheet set (4.4), directs the formed flue gas outward. After contacting the E1 E2 sheet set, it reaches the hood through the middle of the E1 E2 sheet set (4.6). The gas passing through the hood section to the chimney exits from the chimney by reducing the chimney gas temperature to a minimum.
In order to solve the problem of noisy operation of the boiler in the prior art, to increase the efficiency of the heat exchanger by making use of the heat in the burner cover (1 ) and to avoid noise pollution, two processes are performed simultaneously without using an additional silencer. In this way, the reflection of the heat generated in the boiler to the external environment is reduced to a minimum and the efficiency of the boiler heat exchanger is increased. The burner cover (1 ) becomes whole with the Manifold with Silencer (1.1 ), the air way (1.8), the fan (1.2), the mixer (1.3), the gas inlet (1.4), the heat insulation (1.5), the sparking plug (1.6) and the intake manifold which further comprises the intake manifold outlet (1.7.1 ). While the fan
(1.2) is suctioning, the cold air drawn by the fan first enters through the silencer manifold (1.1 ) and continues through the airway (1.8). Thus, the heat of the flame formed in the combustion chamber is transferred to the cover while the cold air is heated while the cover is cooled. The heated air coming from here enters the mixer
(1.3) by means of the intake manifold (1.7). The gas entering through the gas inlet
(1.4) mixes with the heated air entering from the intake manifold (1.7) by means of the mixer (1.3) and the mixed gas and air passes through the air gas mixture way (1.9) to the burner (2) by means of the fan (1.2). The ignition is made in the burner (2) with the aid of the sparking plug (1.6). Thanks to this circulation, the manifold with silencer (1.1 ) acts as an exhaust and minimizes the noise generated by the friction of the air. At the same time, the heat passing through the insulation material inside the burner cover is cooled by the air passing through the burner cover and the heat that may cause human health in contact is prevented. The heat we receive from here increases the efficiency of the heat exchanger by giving a mixture of hot gas and air into the heat exchanger.
