1. Overview of high temperature and high pressure fluid electric heater:

The high-temperature high-pressure fluid electric heater includes a housing and a heating tube. A metal tube is installed in the inner cavity of the housing. One end of the metal tube passes through the housing as a heating medium outlet, and the other end passes through the housing as a heating medium inlet. The inner diameter walls of the metal pipe are evenly arranged, and each heating pipe is placed close to the inner diameter wall surface of the metal pipe; the shell includes a heat insulation shell and a heat insulation layer covering the heat insulation shell. It can be seen from this: this patent can heat gaseous and liquid media under high temperature and high pressure, with high pressure (IOMpa), high temperature resistance (above 800 degrees Celsius), and low cost (cost is one-fifth of high-pressure, high-temperature boiler ), Fast heating, high efficiency and other advantages.



The high-temperature high-pressure fluid electric heater is an internationally popular high-quality long-life electric heating device. It is used to warm up, keep warm and heat flowing liquid and gaseous media. When the heating medium is heated by an electric heater under pressure, the principle of fluid thermodynamics is used to evenly remove the huge heat generated during the operation of the electric heating element, so that the temperature of the heated medium reaches the user’s process requirements.

2. Working principle of high temperature and high pressure fluid electric heater:

 The high temperature and high pressure fluid electric heater is a kind of electric energy consumption converted into heat energy to heat the material to be heated. During operation, the low-temperature fluid medium enters its input port through the pipeline under pressure, along the specific heat exchange flow path inside the electric heating container, using the path designed by the principle of fluid thermodynamics, to take away the high-temperature thermal energy generated during the operation of the electric heating element. The temperature of the heated medium is increased, and the outlet of the electric heater obtains the high-temperature medium required by the process. The internal control system of the electric heater automatically adjusts the output power of the electric heater according to the temperature sensor signal of the output port to make the medium temperature of the output port uniform; when the heating element is over temperature, the independent overheating protection device of the heating element immediately cuts off the heating power to avoid Overheating of the heating material causes coking, deterioration, carbonization, and in severe cases, the heating element burns out, effectively extending the life of the electric heater.

Fluidtherm Construction Design

Fluidtherm, Thermic fluid heater, consists of two concentric coils in which inner coil acts as a radiation zone and outer coil act as a convection zone.

Flue gas velocity is generally higher between the 2 coils and between the coil and the outer shell, so higher the velocity higher will be the convective heat transfer between the flue gas and fluid.

Thermic fluid heaters can be made either 3 pass or 4 pass depending on the design of thermic fluid heater and the type of fuels to be burnt. The efficiency of the heater increases with an increase in the number of passes.



Working Process of Thermic Fluid Heaters

The maximum temperature of 350℃ of thermal fluid can be achieved in a Fluidtherm although the higher temperature of the thermal fluid can be achieved provided the temperature of fluid does not exceed the auto-ignition temperature.

Thermodyne, Fluidtherm – Thermic Fluid Heater also consists of a deaerator and expansion tank. The density of fluid decreases with increase in the temperature of fluid so a tank is generally installed in a process to help accommodate the extra volume of fluid which is increased due to increase in the fluid temperature. For every 100℃ rise in the fluid temperature, the volume of fluid increases by 7% so expansion tank is added to take care of that extra volume.

Deaerator tank is combined with the expansion tank and is generally used to vent out air from the fluid which acts as resistance in transferring heat to the fluid.

Five points for attention in operation of thermopac 5 lakh kcal thermic fluid heater are summarized.

1. The heat transfer oil boiler uses the large heat transfer oil as the heat carrier of oil and gas. The system shall be equipped with expansion tank, measuring instrument and control device, etc.

2. Check carefully in use to prevent water, acid, alkali and low boiling point substances from leaking into the use system. The system shall be equipped with filter device to prevent impurities from entering and ensure the purity of oil products.



3. When the heat transfer oil boiler is put into use, at the beginning of operation, start the circulating oil pump first, run for half an hour, then ignite and heat up. When it is used for the first time, the temperature shall be raised slowly, about 20 ℃ per hour. When the temperature rises to 180 ~ 200 ℃, it can be put into normal use after holding for a period of time.

4. After half a year of use, the oil analysis shall be carried out. After long-term use, if poor heat transfer effect or other abnormal conditions are found, the oil shall be analyzed and added or replaced according to the analysis results.

5. In order to ensure the normal service life and heat conduction function of heat conduction oil, it is strictly prohibited to use the heat conduction oil boiler over temperature.

Once the squib will directly lead to leakage of the heat transfer oil, it will cause the heat transfer oil furnace to blast. In order to guard against the onset of this situation, we need to pay attention to the time of the device. We must select the device company that has experience. The welding time should be carefully and carefully. We can not use the screw to connect the interface. The flange connection should be properly used. data of.

 

    Combined with many years of project experience, the reason why the heat-conducting oil furnace is bursting is: When the quality of the heat-conducting oil in the heat-conducting oil boiler is not pure, the amount of carbon is generally beyond the specification, or there are impurities such as moisture inside, when we conduct heat When the temperature in the oil boiler is too high, the phenomenon of fuel injection or ignition may occur. Perhaps the moisture in the boiler is vaporized due to excessive temperature, resulting in too much pressure in the heat transfer oil boiler and overpressure blasting.

 

    Therefore, our staff must punctually sample and analyze the heat transfer oil we use, timely grasp the quality of the oil, analyze the quality and the cause of the sudden change, and prepare for the cause, and punctuality to the heat transfer oil furnace The amount of heat transfer oil is compensated.

 

    Of course, the heat transfer oil that we add to the heat transfer oil boiler needs to be qualified and dehydrated. If there is any problem with the quality found in this process, we should promptly adopt the corresponding countermeasures to deal with it.

Precautions when stopping the hot blast stove: The hot water hot blast stove is a hot blast stove that produces hot water. It refers to the use of thermal energy released by fuel combustion or other thermal energy (such as electrical energy, solar energy, etc.) to heat water to a nominal temperature. Thermal device. So what do we need to pay attention to when using a water heater for intermittent heating? Let us have a look now!



  (1) When the hot blast stove stops heating, if it is a normal shutdown furnace fire, the blower should be stopped first, then the induced draft fan should be stopped, and the coal supply should be stopped, but the circulating water pump cannot stop. The pump water still evaporates due to the closing of the pump, and the pump still needs to continue. run. When the system water temperature drops below 50-60 °C, stop the circulating water pump. If the interval between intermittent heating is short, it is not necessary to stop the circulating water pump.

  (2) When starting the furnace again, the circulating water pump should be turned on first, so that the water in the system reaches the normal cycle, the induced draft fan and the blower are started, the grate and the coal charging system are started, and the coal seam combustion is gradually recovered. When the furnace is shut down for a long time, the coal seam is burned and then covered with a thick coal seam for pressure ignition.
