Microcomputer Automatic Calorimeter for Solid Fuel Combustion Heat Analysis

Product Overview

This microcomputer automatic calorimeter delivers high-precision thermodynamic measurement for solid combustibles, enabling industrial laboratories to evaluate the gross and net calorific value of coal, coke, petroleum coke, and coal gangue with exceptional repeatability. Engineered around an automated oxygen bomb architecture, the system integrates quantitative water dosing, automated ignition, isothermal temperature tracking, and dynamic cooling correction within a single benchtop footprint. By replacing manual liquid handling and ambient heat transfer estimations with automated closed-loop routines, the equipment maximizes testing throughput while eliminating human error.

Designed primarily for thermal power plants, metallurgical complexes, commercial coal inspection facilities, petrochemical refineries, and regulatory quality-supervision institutes, this unit fulfills the demanding analytical requirements of international combustion testing protocols, specifically aligning with GB/T 213-2008 standards. The instrument accommodates high-volume sample throughput, completing routine combustions in approximately 15 minutes without sacrificing baseline stability or temperature sensitivity.

Built for continuous industrial operation, the apparatus features heavy-duty inner and outer water jackets, precision-machined flow control circuits, and robust 24V ignition electronics that perform dependably under rigorous lab conditions. Industrial procurement teams and laboratory managers can rely on its consistent thermodynamic capacity calibration, software-driven data verification, and stable Windows-based processing architecture to deliver audit-ready results across years of intensive commercial testing.
