Application of Economizer Flue Gas Bypass in 330MW Boiler
0. Introduction Thermal power plants remain a cornerstone of global electricity generation, but their environmental footprint continues to draw attention, particularly concerning nitrogen oxides (NOx). NOx, as a key atmospheric pollutant, contributes significantly to smog formation and acid rain. For coal-fired power plants, adhering to stringent environmental regulations requires highly efficient flue gas treatment systems. […]
Anti-Corrosion Spraying Modification of Side Water Wall in a Coal-Fired Boiler
Background The #1 unit of a power plant is a 660 MW ultra-supercritical coal-fired unit. The boiler in use is a B&WB-2091/26.15-M model, designed and manufactured by Beijing Babcock & Wilcox Co., Ltd. It features a once-through intermediate reheating system with a single furnace and balanced ventilation. This outdoor-arrangement boiler employs a dry slag removal […]
Measurement and Control of Boiler Drum Liquid Level
The safe and economical operation of a boiler depends on the precise control of key parameters. Among these, the stability of the boiler drum liquid level is particularly important, as it reflects the dynamic balance between the boiler load and the feedwater flow. If the drum liquid level is too high, the steam-water separation process […]
Research on Industrial Boilers in a Certain City: Energy Efficiency and Saving Strategies
China faces a relative shortage of high-quality energy resources with low per capita energy ownership globally. Its manufacturing, led by high-energy-consuming equipment, has hindered industrial economic growth.

Enhancing Energy Efficiency with Low-Temperature Economizers in 330 MW Power Plant Units
In power plant generators, coal-fired boilers hold a relatively important position. During their production and operation, various heat losses inevitably occur, among which the heat loss from flue gas emission is the largest, accounting for about 65% of the total heat loss. Relevant data shows that when the heating surface of a coal-fired boiler in […]
Power Plant Boiler Steam Pipeline and Support Bracket Safety Inspection Method
Introduction The tragedy of the “8.11” high-pressure steam pipeline rupture and explosion accident in Dangyang, which took place in 2016, is etched in our memories. This catastrophic event led to the loss of 22 lives, inflicted four serious injuries, and incurred a direct economic loss exceeding 20 million yuan. The steam pipelines in power plant […]
