The gate gate is a new type of gate gate developed by our company based on the characteristics and user experience of similar ash and powder gate gates at home and abroad. This series of coal gates is suitable for installation in the lower part of the raw coal bunker of power plants. According to the working condition of the coal mill: control the flow rate of raw coal by opening and closing. It can also be used as an electric gate for discharging powder and granular dry materials. Coal gates are used to isolate raw coal from the lower part of the coal hopper in power plants, and can also be used to isolate granular materials from the ash pipes and coal powder silos under dust collectors and chimneys. There are two types of structures: single gate and double gate. The transmission mechanism of the two door panels of the double gate coal gate is equipped with motion control for opening and closing. The material leaks down from the middle opening, reducing friction on the pipe wall, extending the service life of the pipeline, and reducing labor intensity and working time.

Suitable for sealing air heating of flue gas desulfurization engineering baffle doors in power plants, the sealing air is heated from room temperature to a temperature higher than the flue gas temperature (generally around 130 degrees)

The baffle door is produced and manufactured by Lianyungang Huaneng Electric Power Auxiliary Equipment with imported foreign technology. It adopts a new sealing structure: dual stage soft and hard sealing, and anti adhesion spring plates.

Electric plug-in doors are important auxiliary equipment for boilers, installed on the cold and hot air ducts of boilers in thermal power plants where isolation is required, such as the inlet and outlet ducts of coal mills. This product is reliable in operation, flexible in opening and closing, and tightly sealed, fundamentally solving the shortcomings of previous isolation doors that were not tightly closed and had long closing times. It greatly facilitates equipment switching and shutdown maintenance, and has been widely used in major power plants across the country.

The single axis double speed plate door produced by Huaneng Electric Power Auxiliary Machinery adopts optimized structural design based on the introduction of advanced foreign technology. This product has flexible opening and closing rotation, reasonable driving torque, tight and reliable closing, and long service life. It is an important supporting equipment in the desulfurization system of thermal power plants. Single axis double baffle doors are used on the inlet, outlet, or bypass flue of the absorption tower in flue gas desulfurization systems, or in flue gas denitrification and dust removal systems. The air door usually adopts a louvered double-layer baffle structure, and when closed, sealed air is introduced between the double-layer baffles to achieve the function of isolating and shutting off the flue gas.

The bypass baffle door is produced and manufactured by Lianyungang Huaneng Electric Power Auxiliary Equipment Co., Ltd. with advanced foreign technology. The desulfurization baffle door is used on the inlet and outlet of the absorption tower or the bypass flue of the flue gas desulfurization system, or in the flue gas denitrification and dust removal system. The air door usually adopts a louver type double-layer baffle structure. When closed, sealed air is introduced between the double-layer baffles to isolate and shut off the flue gas.

The split type dual core adjustable shrinkage hole is used to adjust the resistance of the primary air duct on the powder feeding pipeline, so that the primary air velocity at the inlet of each powder feeding pipeline at the burner remains consistent. The specifications are formulated as follows: DN200-DN600, a total of 9 types; The specifications are formulated in English as follows: 18 ", 20", 22 ", 24", 26 ", 28", 30 ", and 32", totaling 17 specifications. According to the degree of wear, the split type dual core adjustable shrinkage hole is divided into two types: ordinary type and wear-resistant type.

The balanced dual core adjustable shrinkage hole is mainly used to adjust the resistance of the primary air duct. The adjustment range of circulation area is 25% to 100% of the cross-sectional area.

The plug-in single core adjustable shrinkage hole is mainly used to adjust the resistance of the primary air duct on the powder feeding pipeline, so that the primary air velocity at the inlet of each powder feeding pipeline at the burner remains consistent.
