Product details
Yixing Steyr Thermal Technology Co., Ltd. is located in Wanshi Town, Yixing City, Jiangsu Province, known as the "Ceramic Capital". It is a department that integrates kiln development and design, as well as high-temperature material research and development. We mainly design and produce high-temperature experimental furnaces, experimental furnaces, atmosphere furnaces, tube furnaces, rotary tube furnaces, vacuum atmosphere furnaces, vacuum atmosphere tube furnaces, box atmosphere furnaces, roller kilns, well crucible furnaces, mesh belt silver burning furnaces, push plate furnaces, lithium positive and negative electrode material kilns, LED fluorescent powder furnaces, forging furnaces, sintering furnaces, pre firing furnaces, rubber extrusion furnaces, silver burning furnaces, aluminum melting furnaces, etc., which are widely used in industries such as electronic components, powders, ceramics, and lithium batteries Today, I will introduce the thermal efficiency of a rotary tube furnace.
The thermal efficiency of a rotary tube furnace is 50-70 ℃
As is well known, the magnitude of thermal efficiency is related to the heat loss of the outlet flue gas, incomplete chemical combustion, and heat dissipation loss to the surrounding medium.
But more importantly, it is related to the temperature and quantity of the flue gas, the * II gas coefficient, and whether the combustion is complete.
The temperature of the flue gas leaving the convection tube bundle should be 100- higher than the temperature of the oil entering the convection tube bundle! 500C0
In most tubular Shanghai, the temperature of the oil crystals entering the convection tube bundle is above 1500C, generally between 300-45D0C. Therefore, it is unreasonable to lower the flue gas temperature below 3000C, and sometimes below 5000C, when there is no auxiliary backup for heat recovery of the exhaust gas (such as air heating, generation of Yan steam, or Yan steam overheating).
Due to the fact that heavy oil with high sulfur flea content is mainly used as fuel in the tubular Shanghai area of the Soviet Union, which has severe corrosion and fast scrapping, it is not suitable to use general orange shaped air TA heaters. This is the reason why most rotary tube furnaces have low thermal efficiency.
However, even when the heat from the outlet flue gas is effectively utilized, the heat loss is still significant due to the high coefficient of over braking air (a=1.8-2) of the outlet flue gas.
Although most nozzles can operate under the condition of excess air coefficient a, 2,. 25-1.3, due to the inability of fuel and air volume to automatically thicken, the over braking air coefficient in the furnace is generally a, 2, 1.5-1.81 during actual operation
When the rotary tube furnace adopts a fully N first mixed nozzle, it can operate at a low and alkaline excess air coefficient. Plate type blow nozzle stove belongs to this category.
Most of the protective devices contribute 5-8% of the heat dissipation to the surrounding medium through the large area of the Shanghai wall. In the plate nozzle dual radiation wall furnace, because the radiation wall is made of coarse nozzles and the well is cooled by the gas air mixture used for combustion, the heat loss is relatively small.
Most of the protectors lose -2% of their heat through the surface of the elbow
