1. Water supply equipment
It is composed of water treatment equipment, water supply tank and feed pump 24. Water treatment equipment is used to remove impurities in water, such as oxygen, calcium and magnesium ions, to avoid scaling and corrosion on the inner wall of steam boiler, and to ensure the quality of boiler water supply. The treated boiler feed water is lifted by the feed water pump and then sent to the upper drum through the economizer.
2. Ventilation
The ventilation equipment includes air supply fan, induced draft fan and chimney. Its function is to provide air for mule fuel combustion and lead out combustion product flue gas from the boiler, so as to ensure the normal combustion, and make the flue gas wash the heating surface at the necessary flow rate of 7a68696466fe78988e69d8331333433626465 to strengthen heat transfer. Finally, the stack with a certain height will exhaust the smoke to the atmosphere to reduce the smoke pollution and improve environmental health.
3. Fuel supply, slag removal and dust removal equipment
This is for conveying fuel to boiler, removing ash and purifying flue gas. Belt conveyor, ash conveyor, ash truck and dust remover, etc. For boilers that need to be pre processed with fuel, fuel preparation such as screening, crushing and coal grinding shall also be included. In addition, the dust remover or flue gas desulfurization and denitrification device installed in the flue at the tail of the boiler is an indispensable auxiliary equipment to reduce the smoke pollution and protect the environment.
4. Check instruments and automatic control equipment
In addition to water level gauge, pressure gauge, safety valve and other instruments installed on the boiler body, in order to supervise, regulate and control the safe and economic normal operation of the boiler equipment, a series of instruments, automatic boiler feed water regulating device, automatic fuel combustion control device, etc. are often installed. Some boiler rooms are also equipped with industrial television and remote control device and even more modern automatic control system, more Scientific supervision. Control boiler operation.
Boiler auxiliary equipment, not every boiler is equipped completely, but with the boiler capacity, type, fuel characteristics and combustion mode as well as water quality characteristics and many other factors to adapt to local conditions, adapt to the times, more practical requirements and objective conditions.

The timely maintenance of the wiper rain increases the frequency of use of the wiper significantly, because the rainy day's road surface and sight are not conducive to driving, if the wiper can not wipe off the rain, it will give you a great danger of driving safety, at this time the wiper It plays a very important role, so it should be more careful to check and maintain it.
Although the windshield wiper is resting on the windshield, it is easy for people to ignore it during daily maintenance. When it is used, it will suddenly discover the problem. Automotive maintenance experts pointed out that in fact, the maintenance method of the wiper blade is very simple. When the car wash, the glass wiper wipes the wiper bar, which can effectively extend the service life of the wiper blade. Regularly check the wiper wiper status, and if there is uneven wiper wipe or clean rain, the emergence of these two situations means that the wiper blade is damaged and needs to be replaced in time.
Pay attention to the rust on the brake pads Most of the brake discs are made of cast iron and are exposed for a long time. They are exposed to the wind and sunlight, and the working environment is rather harsh. Even during the northern rainy season, some rust will be generated on the surface of the brake discs. More or less rust will affect the normal operation of the brake system, so it is necessary to remove it in time.
If there is only a slight rust on the surface, it can be removed by continuous braking while driving. While driving, lightly apply the brakes and use the friction between the brake pads and the brake disc to polish the surface. If the condition of rust is severe and rust is high, the surface of the brake disc will be uneven. In this case, braking may cause vibration of the vehicle body. This kind of rust is usually difficult to remove by continuous braking. Experts suggest that when this happens, it is necessary to go to a regular repair shop for repair, and if necessary, replace the new brake disc.
Correct use of front fog lamps Most urban roads have street lighting. The daily driving does not clearly indicate the importance of the lighting of the lights. When there is no street lighting during rainy days, it is necessary to completely rely on the light of the car body. Although the location of the fog lamp assembly is usually low, the fog lamp has a strong penetrating power and it is easier for the vehicle or the pedestrian to detect it earlier in low visibility weather conditions. However, driving a fog lamp on a rainy day can cause some disturbance to the incoming train. If it is not particularly affected by sight, it is still necessary to keep the fog lamp off. 
Boiler auxiliary equipment mainly includes water supply equipment, ventilation equipment, fuel supply, slag removal and dust removal equipment, steam and water pipes and accessories, detection instruments and automatic control equipment.
â– Car Care Wiper Brake Pads Front Fog Lights The summer rainy season is coming. Frequent rainfall will bring a lot of trouble to car owners. Although the northern rainy season does not continue as long as the South, but in order to ensure driving safety, the owners still have to make more preparations for the safe driving in the rainy season.
