The energy consumption for a house heating may be greatly reduced by replacing a noncondensing gas boiler unit to a condensing unit. To save the operating cost of a heating system, the optimal operation of a boiler unit is necessary. Mathematical models of a condensing gas boiler system, which are composed of dynamic models for a blower, a gas valve, a pump, a pipe, a burner, a boiler heat exchanger, and a hot water heat exchanger, were developed. Control algorithms of a blower, a gas valve, and a pump were selected. Dynamic models along with control algorithms were used to analyse control performances of a boiler system. Simulation was performed by using a computer program. Simulation results showed good predictions of dynamic behaviors of a boiler system. Therefore, dynamic models developed for this study may be effectively used for the optimal control algorithm development and the control performance prediction of a condensing gas boiler system.

Plant availability and safety are affected by the risk of the plant strongly. To reduce the risk, the efforts in every life cycle (plant design, plant equipment procurement and plant operation) of the plant industry are needed. In this paper, we introduce ICT convergence technologies which are carried out in dept. of the energy plant safety technology in KIMM, especially smart plant equipment, plant inspection/maintenance and safety action.
