Abstract

The invention provides a denitration smoke temperature control device based on regulation of a condensing steam turbine set. According to the control technology achieved through the denitration smoketemperature control device based on regulation of the condensing steam turbine set, the requirement of SCR denitration for smoke temperature can be met while deep peak regulation is conducted on the set, and the peak regulation ability of the set is improved. Due to the fact that the peak regulation ability of the deep peak regulation set is fully considered, the maximum peak regulation ability isfully achieved, when a power grid needs load reduction, the electrical load of the set can be reduced to the lowest, and grid operation space is provided for other clean energy. In addition, throughthe condensing steam turbine set provided by the invention, a balance point is found between the electrical load requirement and denitration catalyst requirement, and meanwhile the requirements of deep peak regulation of the electrical load and of the put-in temperature of a denitration catalyst are met.

Description

technical field [0001] The invention relates to the technical field of thermal power unit wide-load denitrification input control, in particular to a denitrification smoke temperature control device based on the adjustment of a condensing steam turbine unit. Background technique [0002] At present, the domestic demand for electricity is growing slowly, and the contradiction of excess electricity is becoming increasingly prominent. With the rapid development of clean energy wind power technology, hydropower technology, and photovoltaic technology, clean energy power generation technology should be given priority in the power dispatching process. However, in some areas, due to the inability of the power grid to fully consume, the problems of abandoning wind, water, and light are becoming more and more serious, which has become the main contradiction affecting the healthy development of clean energy in China for a long time. [0003] At the same time, as the country pays more ...
