What are the common biomass pellet calorific value testing instruments What are the common biomass pellet calorific value testing instruments

Temperature resolution: ≤0.0001K
3.3 Power: ≥0.65kW
2.4 Accuracy: Test results are within the allowable range of standard samples
2.5 Thermal capacity stability: Annual thermal capacity variation ≤0.20%
2.6 Equipped with a spiral tube isothermal system design, creating a controllable and stable internal environment for instrument experiments (composed of an outer bucket and bucket lid, temperature difference <0.05°C), effectively isolating the impact of external environments (such as airflow, temperature, etc.) on the inner bucket; outer bucket water temperature fluctuates <0.05°C throughout the day and <0.01°C during single-sample testing, ensuring accurate and reliable test results;
2.7 The outer bucket uses semiconductor temperature control technology, combining both cooling and heating functions, eliminating the need for additional cold water cooling, ensuring the independence of the inner and outer bucket water systems. After the experiment, the inner bucket water is directly drained into the water tank, and the inflow and outflow of the inner bucket have no effect on the outer bucket water temperature, further ensuring the stability of outer bucket temperature control; a fixed-volume oxygen bomb is used, with a constant volume unaffected by the operator, eliminating changes in inner bucket water volume due to oxygen bomb volume variations, making the thermal capacity more stable;
2.8 Automatic oxygen bomb lifting, automatic oxygen filling and release, automatic oxygen filling pressure detection, automatic oxygen bomb airtightness detection, automatic inner bucket water volume setting, automatic inner bucket water temperature adjustment, and automatic experiment completion; the lifting arm uses a press-down oxygen filling and release mechanism, which is efficient, stable, and clog-resistant; supports automatic pipeline flushing and automatic water change functions, ensuring long-term stability of thermal capacity.
2.9 Inner bucket circulating water path system, easily detachable new stainless steel oxygen bomb combined with a metal inner bucket for fast and direct volume setting, supplemented by an efficient and stable new inner bucket stirring method, enabling faster heat transfer of the oxygen bomb, effectively shortening test time, with continuous single-sample test time ≤12 minutes;
2.10 Uses fixed-volume and fixed-quantity devices, equipped with a semiconductor temperature-controlled constant-temperature water tank that combines both cooling and heating functions. Compared to conventional compressor-based chilled water tanks, it offers more precise water temperature control, lower overall power consumption, and lower noise.
2.11 All data are measured in real-time, true and objective, without using software corrections to alter test results or fabricate data.
2.12 Supports automatic oxygen bomb airtightness detection to avoid test result errors due to oxygen leakage. Features self-diagnostic functions for easy daily maintenance; equipped with a crucible bracket for convenient handling.
