Embodiment Construction

[0021] 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.

[0022] The terms in this manual are introduced as follows:

[0023] 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.

[0024] 2. Boiler thermal efficiency: COP (Coefficient Of Performance), 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.

[0025] 3. Standard coal: also known as coal equivalent, which has a unified calorific val...

Abstract

The invention discloses an energy saving control method and energy saving system for boiler automatic combustion. The energy saving control method and energy saving system for the boiler automatic combustion are used for a heating supply system. The control method comprises the first step that the flue gas oxygen content of the boiler of the heating supply system is detected, the second step that whether the detected flue gas oxygen content is within a setting range or not is judged, and the third step that if the detected flue gas oxygen content is not within the setting range, the blast volume of an air blower or the coal supply amount of a coal feeder of the heating supply system is controlled until the detecting value of the fuel gas oxygen content is within the setting range. According to the energy saving control method and energy saving system, the blast volume meets the requirement for the sufficient burning of fuel, the reduction of the temperature of a hearth cannot be caused by too many blast volumes, and therefore the boiler has the highest heat efficiency.

Description

technical field [0001] The invention relates to heating technology, and in particular to a boiler automatic combustion energy-saving control method for a heating system and a boiler automatic combustion energy-saving system. Background technique [0002] 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 company can say clearly. The rest of the extensive expressions such as "almost", "slightly higher" and "burning well" cannot make heating companies seek to improve thermal efficiency, reduce energy waste, and reduce costs. Moreover, the above-mentioned extensive control technology causes energy waste, which...
