談及與煅燒爐的熱量-統一干燥

幾十年來，Heyl & Patterson已建成機器稱為旋轉式煅燒爐，在高溫室的過程材料。煅燒爐的間接熱源，保證在加工過程中熱量和產品之間的完全分離。隨著企業尋找材料，具有更細的顆粒大小和均勻的質量，這些機器已經升級的好處和滿足他們的要求。

一種旋轉式煅燒爐由合金鋼氣缸內部旋轉一個電動的或氣體加熱的爐。產品或材料貫穿該氣缸，這是由一個外部驅動機構打開。以關閉的筒的端部，固定殼體使用。上游住房，使制造商能夠連接他們的給料設備，和下游的住房privides一個連接氣體凈化設備的收集和處理排放的蒸汽，從產品的。煅燒爐中，也可能包含的水噴霧冷卻器冷卻到安全溫度，一旦它已經被處理的材料。

煅燒爐中進行高溫處理（1000華氏度 - 2100華氏度），在其可控氣氛。煅燒爐可用于：

氧化鐵生產
貴金屬回收
催化劑的制備
環境清理
特殊化學品
烘焙的木質生物質
煅燒爐是能夠控制的確切的氣氛要求的任何類型的材料。有了這項功能，分解爐能夠提供增強的特性到成品。

的材料進料器連續地介紹了產品的氣缸的內部。由于氣缸的旋轉，材料進入加熱爐部分，用于熱加工。在這個時候，在氣缸內的氣氛是在一個不斷控制，預先確定的條件。在離開爐子之后，產品可以進入的冷卻部，在那里它被冷卻到所需的溫度。^后，從煅燒爐排出，通過下游的住房。

煅燒爐的熱源可以是電動的電阻線或燃料燃燒器。該熱源加熱的缸的表面上。反過來，氣缸由從外部的輻射傳熱或間接熱傳遞，并直接接觸的產品，并在氣缸的兩側的熱表面加熱的材料。

高爐熱操作組，或區域。每個區域獨立運作，并控制加熱過程中的一個階段。該階段可以是：

干燥階段 - 該產品的游離水分干燥
煅燒階段 - 該產品的生產溫度升高至
浸泡階段 - 溫度被保持在預設的時間，以完成該過程
冷卻階段 - 將產物冷卻到安全溫度的處理，一旦它已經被處理
此帶狀排列允許每個處理階段獨立行事，而不會不利地影響下面的階段。作為一個例子，該產品的濕氣可能會波動，需要更多的干燥煅燒階段之前。增加的濕度水平爐，以提高干燥區中的熱量輸入的信號。因此，現有的材料已經被其設計條件相等的煅燒帶，并沒有改變該區域的運行效率。

煅燒爐的操作有幾個重要的特點：

溫度曲線 - 因為它有多個熱輸入，從爐的熱輸入可以匹配的熱量需求的過程。這將導致在一個高登陸平均溫度，這是在加熱過程中的動能驅動力。保持高度數平均溫差，減少了處理時間，提高了熱效率。
間接加熱源 - 因為熱源從過程流中除去，該材料是理想的條件下。這提供了一個更均勻的高質量的產品。此外，氣氛和壓力可以被控制的各個階段。
小截斷氣體系統 - 關閉氣體處理設備被簡化，更小和更便宜的，因為它的尺寸僅用于的過程氣體的體積。熱源直接排放到環境中，因為它們保持潔凈和未受污染的過程。
回轉煅燒爐提供：

有效的高溫處理
高的傳熱率
^小化的設備的尺寸和成本
提高了產品質量的處理氣氛的控制由于
減少對環境造成的風險低，治療的氣體體積
憑借其高效率和多功能性，分解爐是各種各樣的專業應用的理想選擇。 Heyl & Patterson的Renneburg部門工作回轉煅燒爐試驗廠測試實驗室在匹茲堡，PA，可以決定^好的方式來實現所需的任何應用程序的結果。我們的測試實驗室提供了幾種可用的解決方案，在不同類型的熱加工設備的形式。

For decades, Heyl & Patterson has built machines known as rotary calciners that process materials in a high-temperature chamber. The calciner's indirect heat source guarantees complete separation between heat and product during processing. As companies look for materials that have finer particle sizes and uniform quality, the benefits of these machines have escalated and meet their demands.

A rotary calciner consists of an alloy steel cylinder that rotates inside an electrically or gas heated furnace. The product or material runs through this cylinder, which is turned by an external drive mechanism. To close off the ends of the cylinder, stationary housings are used. The upstream housing allows manufacturers to hook up their feeding equipment, and the downstream housing privides a connection for off-gas cleaning equipment to collect and process the vapor that is emitted from the product. The calciner could contain a water spray cooler that cools the material to a safe temperature once it has been processed.

The calciner performs high-temperature processing (1000 degrees F - 2100 degrees F) within its controlled atmosphere. Calciners can be used for:

Iron oxide production
Precious metal recovery
Catalyst production
Environmental cleanup
Specialty chemicals
Torrefaction of wood biomass
The calciner is capable of controlling the exact atmosphere requirements of any type of material. With this capability, the calciner can provide enhanced characteristics to the finished product.

A material feeder continuously introduces the product to the inside of the cylinder. As the cylinder rotates, the material moves into the heated furnace section for thermal processing. At this time, the atmosphere inside the cylinder is at a constantly controlled, pre-determined condition. After exiting the furnace, the product could enter the cooling section where it is cooled to the desired temperature. Finally, it discharges from the calciner through the downstream housing.

The heat source for calciners is either electric resistive wires or fuel fired burners. The heat source heats the surface of the cylinder. In turn, the cylinder heats up the material by radiation heat transfer or indirect heat transfer from the outside, and direct contact of the product and the hot surface of the sides of the cylinder.

The furnace heat is operated in groups, or zones. Each zone operates independently and controls one stage of the heating process. The stages can be:

Drying stage - The product is dried of its free moisture
Calcining stage - The product is elevated to the production temperature
Soaking stage - The temperature is maintained for a preset time to complete the process
Cooling stage - The product is cooled to a safe temperature for handling once it has been processed
This zonal arrangement allows each processing stage to act independently without adversely affecting the following stage. As an example, the product moisture may fluctuate, requiring more drying before the calcining stage. The increased moisture level signals the furnace to raise the heat input in the drying zone. Therefore, the exiting material has been equalized to its design condition for the calcining zone, and not changing that zone's operating efficiency.

The calciner's operation has several important features:

Temperature profiling - Because it has multiple heat inputs, the heat input from the furnace can be matched with the heat demand of the process. This results in a high Log Mean Temperature, which is the kinetic driving force in the heating process. Maintaining a high Log Mean Temperature reduces the process time and increases thermal efficiency.
Indirect heat source - Because the heat source is removed from the process stream, the material is subject to ideal conditions. This provides a more uniform quality product. In addition, atmosphere and pressure can be controlled throughout the various stages.
Small off-gas system - Off-gas treatment equipment is simplified, smaller and less expensive because it is sized only for the volume of the process gas. The heat source is vented directly to the environment because they remain clean and uncontaminated by the process.
The rotary calciner provides:

Efficient high-temperature processing
High heat transfer rates
Minimized equipment size and cost
Improved product quality due to the control of the processing atmosphere
Reduced environmental risks due to the low, treatable off-gas volumes
With its efficiency and versatility, the calciner is the ideal choice for a wide variety of speciality applications. Heyl & Patterson's Renneburg Division operates a rotary calciner at its Pilot Plant Testing Lab in Pittsburgh, PA that can determine the best way to achieve any application's desired results. Our testing lab offers several available solutions in the form of various types of thermal processing equipment.
