The combustion of fuel generates heat and is transferred to the water in the boiler. The effect of heat transfer is called thermal efficiency. At present, in foreign countries, High Thermal Efficiency Gas Steam industrial boilersrequire the following conditions to ensure high thermal efficiency, high safety performance and low fuel consumption:
1. The residual heat of flue gas can be recovered by condensation or semi-condensation technology, thereby greatly reducing the exhaust gas temperature and minimizing the heat loss of exhaust gas.
2. Using the intelligent control device for combustion, according to the continuous monitoring of the composition of the flue gas, the combustion air-fuel ratio is automatically adjusted to ensure that the air-fuel ratio is always maintained at an optimum state, thereby substantially avoiding incomplete combustion heat loss and continuously reducing the heat loss of the exhaust gas.
3. Adopt IoT technology to supervise online boiler scale and scientifically guide water quality control and descaling. If the manufacturing process and manufacturing technology are scientific and rigorous, High Thermal Efficiency Gas Steam industrial boilers will become more and more common, bringing enough benefits to enterprises and institutions.
