Regenerative heating furnace is generally composed of the following parts: inside the furnace, material system software, tunnel ventilation system software, smoke prevention system, and refrigeration system. Waste heat recovery and utilization device, etc.
Regenerative heating furnace furnace is a space composed of furnace wall, furnace roof, and furnace bottom (including foundation), and is a place where metal is heated.
What are the usual heating methods for regenerative heating furnaces
Regenerative heating furnace walls are divided into side walls and end walls. The thickness of the side walls is usually 1.5-2 bricks thick. The thickness of the end wall depends on the specifications of the natural gas burner and hole, and is generally 2^-4 brick thickness. The furnace wall lining of the regenerative heating furnace is made of refractory bricks, plus heat insulation materials. The application of refractory castables and plastic construction is increasing. The furnace wall business is outsourced with a 4^-11mm thick steel plate casing. The furnace wall has furnace mouth, peep hole, natural gas burner hole, temperature measuring hole, etc. To avoid damage by cutting bricks, the furnace wall should try to prevent immediate additional load, and prefabricated components such as furnace mouth and cooling circulating water pipes should be supported on a steel frame Structurally.
So what are the heating methods of the regenerative heating furnace? How to do it well, let’s take a brief look.
1. The heat transfer of the regenerative heating furnace: the heat transfer is the direct contact of objects with different temperatures (or objects with temperature differences) because of free electric fitness exercises (for stainless steel plates) or molecular structure exercises (for The heat exchanger conditions generated by the furnace gas). This type of heat transfer occurs on the surface and inside of the stainless steel plate and between the stainless steel plate and the furnace bottom;
2. The heat transfer of the radiant source of the regenerative heating furnace: the heat transfer of the radiant source is the whole process of the heat radiation of the object. The higher the temperature, the greater the kinetic energy of the radiant source. This kind of heat transfer exists in the furnace gas to the furnace mouth and furnace. Gas and furnace mouth to the surface of the slab;
3. Thermal convection heat transfer in regenerative heating furnace: Thermal convection heat transfer is the whole process of the heat exchanger when the furnace gas touches the surface of the stainless steel plate, including the heat convection effect caused by the deviation of each part of the furnace gas and the furnace gas Heat transfer in the middle of molecular structure.
Regenerative heating furnace is essentially a collection of high-efficiency regenerative heat exchangers and basic heating furnaces. The key is the heating furnace wall, regenerator, phase conversion system software and its fuel, air supply and smoke prevention System composition. It is more common in the application field.
