Abstract

The invention discloses a steam mixing system for realizing denitrification and temperature raising and its adjustment method, which comprises a driving steam isolation unit, a steam mixing device, a high-pressure heater and an economizer sequentially connected through a steam pipeline. The road is equipped with a pressure and temperature detection device. The inlet of the steam pipeline is connected to a low-temperature and low-pressure steam pipeline. The high-pressure heater is connected to a high-temperature and high-pressure steam pipeline. The mixing device is connected in parallel with a driving steam regulating unit. The feed water passes through the high-pressure heater and flows out after being heated by the economizer. The boiler flue gas enters the denitrification system (SCR) denitrification system after passing through the economizer. And unit operation flexibility, can realize denitrification full load section adjustment, strong ability to adapt to load changes, suitable for flue gas denitrification treatment technology field.

Description

technical field [0001] The invention belongs to the technical field of flue gas denitrification treatment, and in particular relates to a steam mixing system for realizing denitrification and temperature raising and an adjustment method thereof. Background technique [0002] In the current form, renewable energy is developing rapidly. Based on the characteristics of intermittent power generation of clean energy, the demand for adjustable capacity of the power system has increased dramatically. In addition to providing stable power supply, conventional thermal power units also need to undertake the peak regulation obligation of the overall power system. In recent years, with the rapid development of renewable energy, there have been serious abandonment of wind and light, and the consumption of new energy has become a key factor restricting the development of renewable energy; based on my country's energy consumption rules, the proportion of clean energy is increasing, and win...
