Biomass Heat Detection Instrument

Biomass Calorific Value Testing Instrument Biomass Calorific Value Testing Instrument Hebi Biaochuang Instrument Manufacturing Co., Ltd.

Solid biomass samples used for determining calorific value should be prepared as general analysis samples smaller than 1mm. Wrap 1g of the biomass sample tightly with three layers of lens paper of known calorific value, weigh accurately to 0.2mg, and place it into the combustion crucible. Install the ignition wire and cotton thread (ensure the ignition wire does not contact the combustion crucible to avoid ignition failure). Add 5ml of distilled water to the oxygen bomb, carefully tighten the bomb lid, and slowly fill the bomb with oxygen until the pressure reaches 2.8-3.0MPa (28–30 standard atmospheres). The oxygen filling time must not be less than 15 seconds. If the oxygen pressure exceeds 3.2MPa, stop the experiment, release the oxygen, and refill. Place the oxygen bomb into the inner bucket filled with water, ensuring the water level covers the top surface of the bomb lid by 10-20mm. Check the airtightness of the oxygen bomb; there should be no bubbles leaking. If leakage occurs, identify the cause or replace the gasket, then refill with oxygen after addressing the issue. Close the calorimeter lid.

Performance Features:

1. Utilizes an advanced microcontroller system to control the instrument, enabling automatic water filling, automatic water temperature adjustment, automatic water quantification, automatic stirring, and automatic ignition;

2. Possesses all functions of an intelligent calorimeter, with high testing accuracy, stable performance, low failure rate, and the ability to save system constants and experimental results long-term without loss after shutdown, offering excellent cost-effectiveness;

3. Features an advanced technology LCD screen with an integrated installation method, ensuring the screen's sturdiness. No external computer is required for direct operation;

4. Full Chinese menu-style operation interface. Under the guidance of the large Chinese LCD screen, users only need to prepare the oxygen bomb to complete the entire experimental process. The interface is intuitive, user-friendly, easy to learn, and easy to use. Experimental results are clear at a glance;
