LB-90 Nitrogen Charging OvenPlease do not copy the appearance

1. It consists of a box body, a working chamber, a heating system, gas on/off control, a gas pressure reducing regulating valve, an exhaust port, and other components. The box is processed and welded from thin steel plates, and high-quality stainless steel plates are used for the inner wall of the working chamber. Aluminum silicate fiber cotton is filled between the box and the working chamber as insulation material. The box door and the outer frame of the studio are equipped with insulation sealing strips (using high-temperature resistant sealing strips and compression devices), effectively ensuring the sealing performance of the box body.

2. Small space, low nitrogen consumption, can exchange air 15 times per hour, more uniform temperature, better test repeatability, stainless steel heating tube, with automatic opening and closing vents.

3. High work efficiency, can hold up to twelve full moisture weighing bottles (Φ 70 × 35) at once

Special note:

Stainless steel suitable for all types of coal and suitable for arbitration analysis. Moisture is one of the important indicators in coal settlement, and the accuracy of moisture testing results directly affects the price of coal, according to national standardsGB/T211Method for determination of total moisture in coalGB/T212The "Methods for Industrial Analysis of Coal" respectively stipulate the determination methods of total moisture and air drying basis moisture in coal.

Both standards stipulate that onlyNitrogen dryingThe law applies to the testing of all types of coal,Nitrogen drying methodIt is a standardized arbitration analysis method.

Adopting standards:GB/T212-2008Industrial Analysis Methods for Coal 、GB/T211-2007Method for determination of total moisture in coal.
