One of the main features of the modern Industrial High Temperature Processes (IHTP) are severe requirements for on-line control of production quality, process stability and safety. The main achievements of the present Project are: -- Industrial type diagnostic system for temperature monitoring and control of flame (combustion product) and condensed matter allowing to solve the following technological problems: - oxy-combustion furnaces: air replacement by O2 in combustion, gas flow rate decrease, hot spots elimination;- domestic air burners: decrease of toxic component emission (NOx, CO), burner design optimisation; - laser welding in aerospace industry: reduce the number of quality inspection and repair ratio after welding of titanium alloy TA6V and stainless steel; - plasma cladding: eliminate rejection of expensive cladded parts caused by process instability; improvement of functional properties of cladded layers (dilution, microhardness); - waste treatment by plasma torch: limit heavy metal emission and achieve required glass composition and structure stability; Diagnostic system includes Gas Phase Pyrometer (temperature range 600-2500 C, spectral range 2-4.3 µm, sampling time 20 ms) and Multiwavelength Pyrometer (temperature range 1000-3000 C, spectral range 1-1.7 µm, sampling time 15-1000 µs). -- Special optical fibre accessories (pyrometer heads, water cooled probe, objectives, Infra Red fibres and mounting mechanical systems) providing: - radiance signal telemetry of any required area in industrial installation (internal furnace or burner volume, waste melt pool, cladding or spraying zone, weld seam); ong term stability of optical elements under hostile industrial conditions (heating, dust, water condensation, etc.) Advance InGaAs photodetector (24 elements Linear Array, two-stage thermoelectric cooling element, specially designed cooled package, spectral range 0.9-1.7 µm) -- Simplified model of: - domestic air burner (empirical model based on collected experimental data on burner operation); oxy-combustion furnace (PC software based on radiance transfer model for simulation of temperature fields and heat extracted flux on the furnace load). -- Process control methodology for all end-users applications and prototype of process control system for oxy-combustion furnace containing executing elements and sensors.
