float glass furnace waste heat boile
my country’s current float glass furnace emits a large amount of high temperature flue gas at 400~500℃, and the heat energy carried is equivalent to 35~50% of the total input heat. The use of waste heat from glass furnace waste gas to generate electricity is a comprehensive resource utilization project. The comprehensive utilization of waste heat can not only greatly improve the energy utilization rate of the whole plant, but also reduce the electricity consumption and energy consumption per unit glass production cost, reduce the emission of air pollutants, and reduce the greenhouse effect. The heat generating boiler produced by our company is a water tube boiler, adopting natural circulation, type Ⅱ vertical layout, compact structure and small area. The flue gas in the first flue passes through the superheater and the three-stage evaporator horizontally from bottom to top, and the flue gas in the second flue passes through the two-stage economizer and the two-stage deaerator from top to bottom. The heating surface of the furnace adopts light The bottom of the two flues are equipped with ash hopper, and the top of the boiler is equipped with a drum and a deaerator. In order to facilitate operation and maintenance, a multi-level platform escalator is provided.
1. Specially designed soot blowing device solves the problem of dust accumulation in waste heat boilers in the glass industry.
2. The heating surface of the steel furnace adopts a smooth tube structure, which adjusts a reasonable pitch to prevent dust accumulation on the upper surface.
3. Tube box structure, short installation period, can fully guarantee the quality of manufacturing and processing.
4. Adopting a proprietary sealing structure to reduce the leakage rate of the boiler and improve the efficiency of the boiler.
5. Equipped with equalizing and filtering devices, using higher flue gas flow rate, reducing ash deposition and increasing heat transfer coefficient.
6. The flue gas inlet filter design reduces the ash adhesion on the main heating surface and reduces the flue gas resistance.
