What are the components of a tubular heating furnace? What are the types?
The tubular heating furnace is a direct heating equipment, and the heat transfer method used is radiation heat transfer. So what parts are the tubular heating furnaces composed of? What are the types of tubular heating furnaces? Let's take a look at Kehua's detailed introduction! Tubular heating furnaces 1. The composition of tubular heating furnaces usually consists of the following parts Composition: Radiation chamber: The part that conducts radiation heat transfer through flame or high temperature flue gas. This part is directly washed by the flame, and the temperature is very high (600-1600 ℃), which is the main place of heat exchange (about 70-80% of the heat load). Convective chamber: The heat exchange part mainly based on convection heat transfer is carried out by the flue gas from the radiation chamber. Burner: It is a heat-generating equipment that atomizes fuel and mixes air to make it burn. Burners can be divided into fuel oil burners, fuel gas burners and oil-gas combined burners. Ventilation system: The combustion air is introduced into the burner, and the flue gas is led out of the furnace, which can be divided into natural ventilation and forced ventilation. Tubular heating furnace, including heating furnace body and waste heat recovery system, waste heat recovery system including air preheater, wherein air preheater is composed of two sections of non-condensing air preheater and condensing air preheater, waste heat recovery system There is also a condensate collection pool, an induced draft fan and a blower in the middle. The condensate collection pool is directly below the condensing air preheater, the condensate collection pool is connected with the induced draft fan, and the blower is connected with the condensing air preheater. Using the heating furnace provided by the present invention, the exhaust gas temperature of the heating furnace can be reduced to about 100°C, the partial condensation of the acid-containing water vapor in the flue gas can be realized, and while the low-temperature sensible heat of the flue gas is recovered, part of the flue gas can be recovered. The latent heat of vaporization of acid water vapor further improves the thermal efficiency of the heating furnace and saves energy. Tubular heating furnace 2. Types are classified by furnace structure: vertical furnace, cylindrical furnace, large square furnace Classification by use: chemical reaction furnace, furnace gas heating furnace for heating liquid, furnace for heating miscible fluid It is the relevant information about the tube heating furnace brought by Kehua, I hope it will be helpful to everyone! The operation of the tube heating furnace is relatively dangerous, and everyone must be very careful during the operation.
