Microcomputer Dual Control Oxygen Bomb Calorimeter for Solid Combustibles Calorific Value Determination

Product Overview

This system represents an advanced thermodynamic measurement platform engineered for precise calorific value determinations of solid combustibles. Built around an intelligent microcomputer architecture, the equipment incorporates asynchronous dual-control technology that enables two independent oxygen bomb testing stations to operate simultaneously via a single workstation. By automating fluidics, vessel charging, dynamic thermal equilibration, and numerical data processing, this instrument delivers high-accuracy gross and net calorific values while maximizing laboratory sample throughput.

Designed primarily for high-demand quality control, fuel trade settlement, and standard research workflows, this unit serves foundational roles across power generation stations, coal mining operations, metallurgical coking plants, and third-party inspection agencies. The platform strictly satisfies the rigorous testing mandates set forth in GB/T213-2008 standards for coal calorific determination, delivering verifiable measurement integrity whether analyzing raw coal feeds, prepared coke, petroleum residues, or washery gangue.

Industrial testing environments demand equipment capable of resisting ambient thermal drift and mechanical fatigue. This equipment couples heavy-gauge isothermal jacket stabilization with robust internal fluid management to suppress convective and radiative interference. Equipped with integrated hardware safeguards and predictive fault self-diagnostics, this analytical instrument maintains operational repeatability across multi-shift evaluation schedules, minimizing operator intervention while safeguarding raw data authenticity.

Detail & Parts

Key Features

• Asynchronous Dual-Vessel Architecture: Driven by a centralized microcomputer interface running on an intuitive operating system, this platform enables completely independent asynchronous control over two distinct calorimeter barrels, allowing simultaneous or staggered testing runs without mutual cross-talk or computational lag.
• End-to-End Fluidic and Operational Automation: The internal fluid mechanics system automates quantitative water dosing, pneumatic filling, thermal adjustment, and post-combustion drainage, requiring the analyst only to mount the prepared oxygen bomb before initiating an automated testing sequence.
• High-Precision Temperature Sensing: Featuring an ultra-sensitive thermal acquisition core, the system achieves a measurement resolution of 0.0001 K across its thermal gradient, capturing minute enthalpy variations during primary combustion to guarantee authoritative precision.
• Precision Quantitative Dosing: An integrated automated weighing and volumetric metering mechanism regulates inner vessel liquid charge within a tolerance of ≤ ±0.1 g, eliminating human volumetric error and establishing uniform thermal capacity for every measurement cycle.
• Advanced Cooling Correction Algorithm: Integrated thermal leakage algorithms continuously calculate exchange rates between the inner vessel and the surrounding 30-liter constant-temperature jacket, executing real-time cooling curve corrections that mitigate ambient thermal influence.
• Automated Heat Capacity Calibration: The onboard software automates heat capacity standardization using certified benzoic acid standards, instantaneously computing conversion values, logging historical calibration factors, and applying calibration baselines to sample runs.
• Safe Low-Voltage Ignition Circuitry: Controlled 24 V electrical ignition sequencing ensures positive, rapid ignition of sample wires with integrated continuity sensing and timed thermal curve triggers, eliminating partial burn errors and protecting internal electronics.
• Integrated Data Governance and Reporting: The administrative software suite provides comprehensive spreadsheet compilation, customized statistical reporting, baseline recalculation capabilities, and automatic printout functionality for seamless integration into industrial laboratory management systems.
• Comprehensive Fault Self-Diagnostics: Active diagnostic routines monitor jacket fluid circulation, sensor continuity, and quantitative dosing performance, triggering automatic protective shutdowns and descriptive screen alerts whenever parameters fall outside safe operating windows.
