Embodiment Construction

[0022] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the invention is capable of various changes in different embodiments without departing from the scope of the invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.

[0023] The terms in this manual are introduced as follows:

[0024] 1. Coal consumption: the amount of coal consumed by the boiler per hour, unit: ton / hour (T / h), under normal circumstances, the coal consumption of a 100T boiler is about 13 tons per hour.

[0025] 2. Boiler thermal efficiency: COP (CoefficientOfPerformance), that is, the conversion ratio between the energy consumed by the boiler operation and the heat generated, referred to as the heating energy efficiency ratio.

[0026] 3. Standard coal: also known as coal equivalent, which has a unified calorific value...

Abstract

The invention provides a boiler high-efficiency combustion energy-saving control method and a boiler high-efficiency combustion energy-saving system. The boiler high-efficiency combustion energy-saving control method and the boiler high-efficiency combustion energy-saving system are used for a heating supply system. The control method comprises the steps that S1, the content of oxygen in flue gas of a boiler of the heating supply system is detected; S2, whether the detected content of oxygen in flue gas is within the set range or not is judged; and S3, if the detected content of oxygen in flue gas is not within the set range, the blast volume of an air blower and / or the coal feed quantity of a coal feeder of the heating supply system is controlled until the detection value of the content of oxygen in flue gas is within the set range. By the adoption of the boiler high-efficiency combustion energy-saving control method and the boiler high-efficiency combustion energy-saving system, the blast volume can meet the requirement for sufficient combustion of fuel, the phenomenon that the furnace box temperature is reduced due to the fact that the blast volume is excessively high cannot exist, and therefore the boiler can achieve the highest thermal efficiency.

Description

[0001] The present invention is a divisional application. The filing date of the original application is October 10, 2013, the application number is 201310470243.7, and the title of the invention is: boiler automatic combustion energy-saving control method and energy-saving system. technical field [0002] The invention relates to heat supply technology, and in particular to a boiler high-efficiency combustion energy-saving control method for a heat supply system and a boiler high-efficiency combustion energy-saving system. Background technique [0003] In the traditional heating industry, heat supply is explored based on experience, there is no standard operating data in the industry, heating depends on the weather, and there is no quantitative heating. It is usually said that "burn less in hot weather", how much is this "one point"? No heating company can say clearly. If the weather is colder and burns a little more, how much is this "a little bit"? Also no heating compa...
