Luoyang sigma high temperature electric furnace manufacturer of laboratory ash furnace can produce ash analysis furnace, ash detection furnace, horse boiling furnace for ash analysis and high temperature ash furnace.

The temperature control unit consists micro-pr℃essor based PID controller cum indicator. benefits of using PID controller:

Pr℃essing speed is high

Provides flexibility to alter the system by changing software.

Compact in size.

Operation and maintenance easier.

Maintain precise values

Door options available:

Flap door

Lift door

Front opening door

Heating from 2 sides by ceramic heating plates.

Air inlet and tall chimney give airflow of 5 to 6 changes per minute

Over temperature protection.

Solid state relays provided for low noise operation

Low chamber height holds airflow close to samples for optimum combustion.

Preheating of air before it enters the chamber gives maximum uniformity.

Large flow areas allow large number of samples.

Sample tray and holding handle.

PCRC sheet body - Powder coated steel body assures corrosion resistant furnace and allows working of chamber at high temperature applications.

Digital output – Target and Performance Output of the furnace operations are in digital format(digits) giving precise reading.

Precise Control of Environmental Parameters-The set/ programmable parameters of thefurnace are precise or have less deviation from original value,thus ensuring correct measurement.

Aesthetically designed-Designed according to the standards and principles underlining industry’s aesthetic values.

Corrosion Resistant interior and exteriors-Corrosion resistant coatings like epoxy coatings are applied inside and outside the furnace to prevent against degradation due to moisture, salt spray, oxidation or exposure to a variety of environmental or industrial chemicals/ corrosive agents.

Sturdy Construction - WEIBER furnaces are built with robustness to withstand stress and strain, giving it long life and ability to perform in extreme stress environments.

Ashing is a test to deduce the amount of ash forming material present in a product so as to decide its use in certain applications.Ashing is usually performed by placing the sample in furnace and destroying the combustible (organic) portion of the sample by thermal decomposition using a muffle furnace. Typical ashing temperatures are 450 to 1100 °C. Magnesium nitrate is commonly used as an ashing aid. Charring the sample prior to muffling is preferred. Charring is accomplished using an open flame.

WEIBER Ashing furnaces are Light weight with ceramic wool insulation (instead of Brick insulation). The outer casting is made of double walled thick PCRC sheet, duly painted with attractive stove enamel. The inner casing is made of ceramic wall. The unit is provided with single door (flap type, lift type, front opening). This door is provided with magnetic door closer. This door is provided with l℃k and key arrangement. The triple walled back of our ashing furnaces are provided with two/Four/Six/Eight (size specific) air circulation fans for uniform maintenance of the temperature throughout the furnace.

快速灰化炉

灰化是测定产品中灰分形成物的数量,从而确定其用途的试验应用。灰化通常通过将样品放入炉中,并使用马弗炉通过热分解破坏样品的可燃(有机)部分来完成。典型的灰化温度为450至1100°C。硝酸镁通常用作灰化助剂。*好在消声前将样品烧焦。炭化是用明火完成的。

快速灰化炉是专为煤、焦炭、石油等的快速灰化而设计的高温电阻炉,可供电力、煤炭、化工、冶金、科研院所及大专院校等单位的实验室进行灰化和灰分的测定使用,是常用的煤炭化验设备之一。

风扇辅助烟囱可实现在加工过程中清除炉箱内烟雾。灰化过程在 900-1300℃时均可进行。炉箱容积在 3 到 40 升之间。

温度控制单元由基于微处理器的PID控制器和指示器组成。使用PID控制器的好处:
