Intensification of heat-exchange of a direct-flow steam boiler of a coil type based on an educational laboratory stand

In the work under consideration, using an experimental stand formed by a cylindrical coil, modes of air movement through flue ramjet steam boiler were investigated. Experimental studies have revealed shortcomings in operation direct-flow and proposed ways to increase heat transfer turbulizing gas-air flow convective part flue. The Ansys programmable engineering environment was used simulate exchange between waste gases water exchanger. SpaceClaim program design geometric model. Finite element grid created Icem CFD program. process creation, materials selected designated for each model, temperatures inside exchanger, exhaust gas temperature, boundary conditions them also set. After entering all parameters model calculations carried out results presented form temperature distribution diagram. conclusion, variant further research aerodynamic processes demonstration option presented.
