What are the combustion methods of tanuru ya muffle?

The combustion method of the muffle furnace:

1. Nafasi ya kutosha ya mwako

Flammable substances or fine dust volatilize from the fuel and burn as the flue gas burns. If the furnace space (volume) is too small, the flue gas flows too fast and the flue gas stays in the furnace for too short time, so it cannot be manufactured. Combustible materials and coal dust have been completely burned. In particular, when combustibles (combustible gas, oil droplets) hit the heating surface of the boiler before the boiler is completely burned, the combustibles are cooled below the ignition temperature and cannot be completely burned to form carbon nodules. At the same time, sufficient combustion space is ensured, which is conducive to the full contact and mixing of air and objects, so that combustibles can be fully burned.

2. Muda wa kutosha

Mafuta hayatashika moto hadi yameteketezwa kabisa. Hii inachukua muda zaidi, hasa katika tanuru ya stratification. Mafuta lazima yamechomwa kwa muda wa kutosha. Kubwa kwa chembe zinazowaka, muda mrefu wa kuungua. Ikiwa wakati wa kuungua hautoshi, mafuta hayatawaka kabisa.

3. In order to make the muffle furnace reach the economic operation index, it is necessary to solve the problem of complete fuel combustion.

4. Furnace temperature is high enough

Temperature is the main condition for fuel combustion. The lower temperature required for the fuel to start the violent oxidation reaction is called the ignition temperature. The heat required to heat the fuel above the ignition temperature is called the heat source. The heat source of the fuel ignited in the combustion chamber usually comes from

Heat radiation from the flame and furnace wall, and contact with high-temperature smoke. The temperature of the furnace composed of the heat source must be kept above the ignition temperature of the fuel, that is, the temperature of the furnace must be high enough to continuously burn the fuel, otherwise the fuel will be difficult to ignite and burn.

5. Kiasi sahihi cha hewa

Ni lazima mafuta yawe yamegusana kabisa na yachanganywe na hewa ya kutosha hewani. Wakati joto la tanuru ni la kutosha, kasi ya mmenyuko wa mwako ni haraka sana, oksijeni katika hewa hutumiwa haraka, na hewa ya kutosha inapaswa kutolewa. Katika operesheni halisi, hewa nyingi hutumwa kwenye tanuru, lakini hewa ya ziada haiwezi kuwa nyingi. Vizuri kuepuka kupunguza joto la tanuru.
