Boiler combustion system for producing steam

Abstract

The invention provides a boiler combustion system for producing steam. The system comprises a master control system, a combustion control system and an equipment configuration system. The master control system comprises a PLC master control module and a data collecting module. The PLC master control module comprises a processor, an analog quantity input module and an Ethernet module. Through a fuel and boiler steam load coordination module, parameters adjusted by a boiler steam load adjusting module can be sensed in real time, a fuel amount calculation module can give out the correspondingly-changed boiler combustion fuel amount according to the required change of the boiler steam load, real-time fuel and boiler steam load matching is ensured, boiler normal running is maintained, through an air supply and fuel adaptation module, the fuel amount information is received in real time, the air supply amount coordinated with the fuel amount is prepared, an air supply machine is controlled to reasonably supply air, the air supply amount and the fuel amount are matched, economic combustion is achieved, and the highest heat efficiency of a boiler is achieved.

Description

technical field [0001] The invention relates to the technical field of combustion systems, in particular to a boiler combustion system for producing steam. Background technique [0002] During the use of the boiler, the pulverized coal is transported to the furnace through the powder feeder, and is fully burned after being mixed with the flue gas to emit heat. The furnace water in the water wall absorbs the heat emitted by the pulverized coal through radiation and conduction to form saturated steam, and then The steam is heated by the superheater to form superheated steam, which is supplied to external users, and in this process, the combustion system is the core; [0003] In the existing boiler combustion system, when the steam load demanded by the boiler changes, the heat provided by the fuel combustion is difficult to adapt in time, and the normal operation of the boiler cannot be guaranteed, and the existing boiler combustion system is difficult to adjust the amount of a...

Problems solved by technology

[0003] In the existing boiler combustion system, when the steam load demanded by the boiler changes, the heat provided by the fuel combustion is difficult to adapt in time, and the normal operation of the boiler cannot be guaranteed, and the existing boiler combustion system is difficult to adjust the amount of air blast and fuel supply The proportion of the boiler cannot guarantee the best combustion state of the boiler. At the same time, the existing boiler combustion system is difficult to ensure that there is a certain negative pressure in the furnace, and the thermal efficiency of the boiler is not stable enough. Sometimes the furnace is overheated and sprays fire outwards, which has potential safety hazards. Therefore, the present invention proposes a boiler combustion system for steam production to solve the problems in the prior art
