New design developments of a steam generator with flame tubes derived from a hot water boiler burning agricultural biomass

The low thermal power steam boiler is required by agricultural companies. The studies started from 450-700 kWt boilers with hot water flame pipes, agricultural waste fuel, developed by Enache Morărit. A preliminary analysis demonstrated the feasibility of transforming these boilers into saturated steam ones. The overall dimensions were imposed by the technological possibilities of that company workshop. Starting from these results, this paper analysed the metal consumption by categories of technological components of the boiler (flame tube, housing, tubular plate, convective heat exchanger) with the estimation of transport problems and costs. The main functional indicators had also revealed, which were compared with those from similar existing boilers.
