Abstract

The invention discloses a control method of a boiler group and a control system of the boiler group. The control method of the boiler group comprises the following steps that a pressure value of a steam mother pipe at an outlet of a steam steam-distribution header of the boiler group is acquired, the boiler combustion quantity of the boiler group is determined according to the pressure value, andwhen a plurality of boilers in the boiler group operate simultaneously, a boiler needing peak regulation is determined according to a steam output flow parameter, a sub-drum outlet pressure parameterand a heating return water temperature of the operated boilers, and the boiler needing peak regulation is burned and operated within a preset combustion load range. According to the control method ofthe boiler group, the boiler combustion quantity of the boiler group can be automatically controlled according to the pressure of the steam mother pipe at the outlet of the steam steam-distribution header, the control of the boilers of the boiler group is more convenient, and the control accuracy can be more ensured compared with manual control.

Description

technical field [0001] The invention relates to the field of heat exchange control, in particular to a method for controlling a boiler group and a control system for the boiler group. Background technique [0002] In related technologies, when multiple boilers are running at the same time, personnel need to manually judge the boiler load and boiler outlet steam pressure, manually adjust the combustion load of the boiler burner, and change the operating status of the boiler to meet the steam demand of the boiler. This control method is difficult to achieve accurate control of multiple boilers, and consumes energy, and the control method of multiple boilers is complicated. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the first aspect of the present invention proposes a control method that is more convenient to control multiple boilers at least to a certa...
