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.

Benefited from the upcoming new subsidy policy for new energy vehicles, the stocks in the new energy auto sector performed well yesterday. As of yesterday's close, GAC Group's (10.03%) strong daily limit led the gains, followed by Changan Automobile's 9% increase. In addition, JAC (5.24%), BYD (3.91%), FAW Car (2.65%), and Hippocampus Auto stocks (2.43%) and Shuguang stocks (2.08%) also recorded cumulative gains of more than 2%.
In terms of capital inflows, yesterday, a total of 9 new energy auto stocks achieved a net inflow of funds, and a total net inflow of funds reached 183.4042 million yuan. Specifically, Changan Automobile ranked first in net inflow of funds yesterday, net inflow of funds reached 66.09 million yuan, Guangzhou Automobile Group ranked second, net inflow of funds yesterday reached 30.605 million yuan, Jianghuai Automobile yesterday net inflow of funds reached 29.4225 million yuan, Ranked third, while three stocks such as BYD (158.238 million yuan), Haima Automobile (15.248 million yuan), and SAIC (1345.89 million yuan) also had net inflows of more than 10 million yuan yesterday.
In May 2010, the Ministry of Finance promulgated the Interim Measures for the Administration of Privately-purchased Pilot Financial Assistance Funds for New Energy Vehicles. The pilot period of the subsidy policy is from 2010 to 2012. At present, the pilot has already expired and the extension policy is about to be issued. The Ministry of Finance, the Ministry of Science and Technology, the Ministry of Industry and Information Technology and the four ministries and commissions of the National Development and Reform Commission have reached a consensus that China's new energy vehicle subsidy policy plans to extend for another three years and will expand the scope of the pilot cities.
According to incomplete statistics from China National Automobile Association, in 2012, China produced 12,552 new energy vehicles, of which 11,241 were pure electric vehicles and 1311 were plug-in hybrids; 12,791 new energy vehicles were sold, including 11,375 pure electric vehicles and plug-in type 1416 hybrid vehicles. Comparable caliber comparison shows that the production and sales volume of pure electric vehicles in 2012 increased by 98.8% and 103.9% respectively over the previous year.
Insiders pointed out that in the past, new energy vehicles in China were mainly based on buses, but in recent years private purchases of new energy vehicles have gradually increased, which will stimulate the new energy automotive industry to enter a fast lane. With the increase in the promotion of the private car sector, the domestic production and sales of new energy vehicles are expected to exceed 15,000 vehicles this year.
Guotai Junan believes that public transportation is the most ideal breakthrough for new energy vehicles, especially pure electric vehicles. Under the background of the new government’s efforts to build a new type of urbanization and develop urban public transport, public transport will welcome large-scale purchases and updates. The new energy bus is expected to usher in a good opportunity for development. We are optimistic about Yutong Bus and Ankai Bus. 
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.
