Bone porcelain kiln, use 4

Commonly used with environmental bone porcelain kiln have spirit of fuel gas, liquefied petroleum gas, etc. Fuel gas has many advantages, such as combustion process ( Including temperature, atmosphere, fire, length, etc. ) Easy to control; Easy to realize automatic adjustment; Itself can preheat, with low calorific value of coal gas can obtain a higher combustion temperature, to adapt to the bone China product firing process requirement, or the use of waste heat heating gas and fuel economy. Gas fuel mechanical impurities, less able to adapt to certain purification require strict industrial kiln, bare can realize open flame to burn, is an ideal fuel. But gas fuel or explosive, this also is the bone porcelain kiln problems should pay attention to in the design and production. To solve problems, to ensure the bone porcelain kiln all thermal parameters such as temperature, pressure, atmosphere right stability problem should be in consideration in the design. ( 1) Bone China production by presenting the ratio of gas leakage gas fuel and combustion air can only be carried out within the scope of the burning, this range is called fire concentration range, also called explosive, flammable gas is different, have different fire concentration range. ( 2) Bone China production to keep the normal pressure of gas and combustion-supporting air pressure of gas and combustion air is determined according to the performance of the burner, each burner for gas and combustion-supporting air, bone porcelain production requirements, some pressure range of pipeline gas pressure in the high and low, directly affects the throughput of size, to make normal combustion, bone porcelain production should be according to the better air coefficient of gas and combustion air volume control. If bone porcelain production of combustion-supporting air pressure too low or fuel gas pressure is too high, can make the air quantity is insufficient, the combustible ingredient in fuel cannot fully burning and flue gas discharge, resulting in not burning heat loss, and atmospheric pollution; When the smoke exhaust temperature at or above the gas ignition temperature, and may cause explosion. ( 3) Bone porcelain production in tropical mouth set fire monitor for preheating zone ( Especially close to the kiln head) Temperature is lower, could not reach the ignition temperature of gas, the bone porcelain production once lighted burner is put out, the gas could not be renewed automatically, therefore in the preheating zone and the flue will contain a large amount of gas, it is wasteful, 2 it is easy to cause explosion, so monitoring combustion situation in the process of the tropical burner flame, immediately send out sound and light alarm and automatically shut off the burner gas solenoid valve on the pipeline, before cutting off gas source, avoid the accident. ( 4) Monitoring tunnel kiln preheating zone of the exhaust fan bone kilns to internal pressure is usually negative pressure, the pressure will affect bone the atmosphere inside the kiln, the pressure is normal or not by adjusting the size of the amount of smoke to control, if the malfunction of the exhaust fan can cause bone kilns in flue gas out, the pressure is too high, combustion atmosphere, causing the flue gas flow back, thus affecting bone China product quality. In addition to the set pressure regulating and testing in the design of alarm device, set the smoke exhaust fan and gas main valve chain, exhaust fan doesn't start, the gas main valve to open it. ( 5) For high furnace temperature monitoring of kiln temperature too high can cause bone porcelain product accidents, such as deformation, burning kiln body bone bone porcelain kiln in the design of general thermocouple in the calcining zone set up a separate testing, once the kiln temperature overrun, sound and light alarm immediately and automatically shut off the gas main valve at the same time, to cut off the gas source, protect bone porcelain kiln. Bone porcelain kiln gas problem except to thoughtful design, also the operation of the bone porcelain production, in short, as long as the design and production operations are attention, is guaranteed. — Bone plate is gone. 。 。 。 。 。
