This research aim to improve a combustion system of boiler within increase combustion efficiency and use all out of the energy. The large boilers were used in the industrial factories which consume a lot of energy for production. By oil and gas fuel will be increasing costs everyday cause many factories interested in energy saving with any method technical engineering specifically for production costs and environment effect decreasing. This researching was installed and program was invented in the industrial factory. This industry factory consumed cogeneration energy for fabric dying. The efficiency before installing the software is measured about 65.85 - 71.98% which heat in exhaust gas about 20% of overall energy is filled in the system. After installing heat loss in the system has been fallen until remain about 5 - 12% and efficiency of heat in system has been reached a peak of 80 - 85%.

This research aimed to improve combustion burning system of boiler and to increase burning efficiency and use all out of the energy. The large boilers were used in the industrial factories which consume a lot of energy for production. The Increasing oil and gas fuel costs everyday cause many factories interested in energy saving with any technical engineering methods specifically for production costs and environment effect decreasing. This research program software was installed and invented for the industrial factory. This industry factory consumed cogeneration energy for fabric dying. The efficiency before installing the software is measured about 65.85-71.98% and heat loss by 50% of overall energy in the system. After installing heat loss in the system has been fallen to 5-12% and efficiency of heat in system has been reached a peak of 80-85%.
