Abstract

The invention discloses a low-pressure cylinder few-steam adjusting method of improving electric adjusting capacity of a heat supply unit, and belongs to the technical field of heat supply. A high-pressure cylinder, a low-pressure cylinder, a boiler, a medium-pressure cylinder and a hot-net heat supply system are involved, wherein the boiler, the medium-pressure cylinder and the hot-net heat supply system are connected in sequence; the boiler is provided with an air inlet, a reheat steam inlet, a reheat steam outlet and a main steam outlet, the boiler is connected with an inlet of the high-pressure cylinder through the main steam outlet, an outlet of the high-pressure cylinder communicates with the reheat steam inlet of the boiler, the reheat steam outlet of the boiler is connected with the medium-pressure cylinder, and a regulating valve and the low-pressure cylinder which are connected in sequence are further connected beside the part between the medium-pressure cylinder and the hot-net heat supply system in sequence; and the invention further provides a low-pressure cylinder few-steam operating method for improving the electric adjusting capacity of the heat supply unit. The electric output adjusting capacity of the heat supply unit is improved.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of heat supply, in particular to a low-pressure cylinder steam-less regulation method for improving the electric regulation capability of a heat supply unit. [0003] 【Background technique】 [0004] The steam inlet flow rate of the low-pressure cylinder of the existing heating unit has a low limit requirement, and its electric output is determined by the heat supply, that is, the electricity is determined by heat, and can only be adjusted within a small range. The operation mode of "fixing power by heat" limits the adjustment ability of the heating unit's power output and affects the consumption of renewable energy. [0005] 【Content of invention】 [0006] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a low-pressure cylinder less-steam adjustment method for improving the electric adjustment ability of the heating unit. [0007] In...
