On Line Simulation Algorithm on Exhaust Gas Heat Loss for Industry Natural Gas Boiler

Owing to environmental protection and energy conservation, industry natural gas boiler will be used increasingly, whose energy conservation work has become more obvious. Exhaust gas heat loss is the most important of all heat loss, so study a site shortcut calculation for exhaust gas heat loss is important. Exhaust gas heat loss calculation involves the on-site running data and the natural gas analysis data, so the MATLAB software is adopted in the paper to program the calculation of exhaust gas heat loss, and fit natural gas quality data by the regression analysis, then simulation the exhaust gas heat loss calculation in the field, which could calculate the exhaust gas heat loss quickly on scene. Using field test data for validation, which show that the fast simulation algorithm has higher accuracy.
