big size energy save steam boiler
The main role of the superheater is heated to saturated steam into superheated steam. When the boiler load changes, to ensure that the temperature of the superheated big size energy save steam boiler within the allowable range of fluctuation. Currently superheated steam boiler plant was maintained at a temperature of 540-555 ℃.
Low NOx Burners – Ultralow NOx boiler burners provide stable combustion at lower flame temperatures with lower excess air and offer high turndown (up to 12 to 1 for natural gas), resulting increased combustion efficiency – more energy is available for the load, as less heat from the combustion process is needed to heat combustion air. Depending on the burner style and configuration, some ultra low NOx burners can achieve single digit NOx emissions without the use of flue gas recirculation.
Water tube boiler structure and characteristics (the single vertical water tube boiler drum): a single longitudinal drum furnace wall water tube boiler is divided into light and heavy monolith furnace furnace furnace wall bulk are two, by the vertical drum, water wall tube, and around convection bank set box. Configured features: the central drum longitudinally disposed upper portion of the furnace, and the convection tube sets are disposed on both sides of the waterwall tubes of the furnace, symmetrical, with A similar shape. Smoke vents high temperature flue gas from the furnace into the left rear of the left convection pass forward through the drum from the front end of the transverse flue, the convection pass off to the right person, and then flows back to the front by the economizer, via lead fans and chimneys.
It is understood, Shaanxi Province, 2018 - Continuing to promote the 2019 inspection work in key areas of defense sky war, now in its third phase. November 22, according to the requirements of the program of work for the inspection team to carry out all the Guanzhong area of Shaanxi Province counties (cities, districts) inspection work, inspected 262 units, identify problems and 49, have been transferred to the supervision of Shaanxi Province 20 .
20 environmental issues in the supervision, accounting for 8 in Xi'an, Weinan City, accounting for 7, Baoji City accounted for two, accounting for two Xianyang City, a Korean city of Tongchuan City, Yangling Demonstration Zone and the New West Ham is not problem found.
More units found the problem, companies of "scattered dirt," the one, accounting for 5%; industrial pollution prevention and control 10, accounting for 50%; a coal-fired boiler renovation, accounting for 5%; comprehensive management of dust 1 , accounting for 5%; complaints 4, accounting for 20%; at three open burning control, accounting for 15%.
