The information released by the China Automotive Technology and Research Center shows that in August this year, the sales of automobiles exceeded the expectations of most people, which was an increase of 15.09% compared with the previous period and ended the decline for three consecutive months, a year-on-year increase of 55.72%. Although there is a certain gap compared to the first half. However, this does not mean that the auto market has entered a period of rapid growth. The arrival of the so-called "automobile inflection point" despite all expectations of the future "golden nine silver ten." In terms of the increase, the market base in 2009 is very large, and it will not be possible to see such rapid growth again this year. In addition, from the second half of 2009 to the first half of this year, the rapid growth for more than a year has exceeded the society’s ability to sustain the growth of automobiles. The problems caused by automobiles, such as congestion, safety, environmental protection, and energy, have been discussed. many. This situation will affect the central government’s support for the development of the automobile market. It will even introduce different measures to control the development of the automobile. Second, it will cause problems due to the increase of automobiles, such as traffic difficulties caused by congestion, parking difficulties, etc. Affected some consumers' desire to buy. We have always emphasized that the excessively high rate of development of Chinese automobiles is not sustainable, and it advocates a balanced, steady and sustained growth without major ups and downs. It is beneficial to the auto industry itself, to the country’s macroeconomic development, and to the formation of automobile society. . Therefore, just relying on the sales rebound in August is not enough to explain the turning point in the market, and has entered a period of rapid growth. We can't just look at the market to pick up a bit and set it up immediately. When we look at the market tightening, we can immediately lower our target. This will cause the company to be thrown out of the car sooner or later.
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.
