small water steam boiler

Matters needing attention in exhaust discharge of Gas-fired Steam BoilerThe gas-fired small water steam boiler is equipped with two sewage valves in series on the sewage pipes at the bottom of the boiler and the bottom of the lower header, one near the boiler and the header is the slow opening valve and the other one is the quick opening valve. When discharging the sewage, the slow opening valve should be opened first, and then the quick opening valve shall be slightly opened. Preheat the pipe and turn it on. In order to make the sewage discharge effect better, the quick opening valve can be switched on and off several times. After the discharge, close the quick-opening valve, then close the slow-opening valve, and finally open the quick-open valve to drain the water between the two valves. Notice: 1 before discharging the boiler water should be adjusted above the normal water level, the water level should be strictly monitored in order to prevent the boiler water shortage caused by the sewage discharge. After sewerage interval, use your hand Touch the drain pipe after the sewage valve to check whether the drain valve leakage, such as the feeling of heat, indicating that the discharge valve leakage, should find out the cause and eliminate. 2 in line with the principle of frequent discharge, less discharge, uniform discharge, discharge at least once per shift, All sewage pipes shall be discharged in turn to prevent deterioration of boiler water quality and clogging of sewage pipes, and even cause water cycle damage and pipe burst accidents. 3. Discharge should be carried out at low load and normal working pressure. At this time, pot water boiling ease, slag pollution easy to precipitate, pollution effect is good. (4) sewage discharge operation should be repeated several times, depending on anti-impact force to make slag scale stirring, and then concentrated discharge, so that the sewage effect is good.

Boiler pressure and boiler pressure difference between what is fact, many corporate buyers boiler for the difference between the two is do not understand. So for the boiler, it is the choice very difficult. Let alone teach other people how to recognize the pressure, atmospheric hot water boiler and pointed out their characteristics. So the need for boiler and pressure boiler pressure difference what the specific detailed understanding of, one, to see changes even when the furnace pressure is low cost pressure hot water boiler, furnace pressure and atmospheric pressure is always the same hot water , does not change with temperature. Pressure boilers, by contrast, due to the furnace system is a closed vessel and piping components will naturally change along with the increase in water temperature. This is a more intuitive way to distinguish between these two pressure variations from the furnace. Second, the problem to see the water level control operation in order to achieve atmospheric pressure, the boiler is connected to the inlet and outlet of the circulating pump, the intake of hot water heated in the boiler to the user. Return pipe and boiler water inlet into the water is equal to the user's necklace. Thus, the presence of level control pressure hot water boiler problem top box remains connected to the boiler when the irrigation tube, the presence of level control problems. Pressure hot water boiler water level control problems, this is an important distinction. Third, look at the structure of limitations compared with pressurized hot water boilers, pressure hot water boiler has a lot of structural parameters. Turbocharged different boiler structure strict restrictions on the boiler capacity, and parameters of the installation location, only reasonable pressure hot water boiler heating surface arrangement to ensure the reliability of the water cycle, limitation on the structure is small. It can be designed, constructed and installed in accordance with the actual needs of the user to a large extent, but also more flexible.

Recently, Xuzhou City ushered in the good weather blue sky, sweetness and light, a set of numbers from the Xuzhou municipal environmental protection department made us confident to bring back the blue sky. According to the latest air quality in the province informed that this year, two good days in Xuzhou City 73 days, an increase over last year eight days; PM2.5 concentration of 78μg / m³, the concentration of upward momentum have been effectively curbed. The atmosphere improving governance has achieved victory.

Since April this year, Xuzhou municipal government set up the city's Operations Command prevention tackling air pollution, and the establishment of 16 specialized working groups in accordance with the classification of remediation tasks, the relevant departments to deploy officers to concentrate on work, concentrate on promoting the prevention and control of air pollution crucial action. At the same time, Xuzhou developed and issued in the history of the most aggressive, the most comprehensive measure of the "Xuzhou City in 2018 tackling air pollution control program," the task of governance engineering, project oriented, technology node.

First, action aimed at the city's 13,654 "messy dirty" business, and sort of closure to ban or stop crime measures. "Coal-burning pollution" key problem is the political commissar of the governance of Xuzhou City, after the operation began, to more than 10 tons of steam coal-fired boilers implementation of classification regulation, the city's 18 coal-fired thermal power companies implement flue gas treatment project off white, investigate and shut down downtown bulk coal processing operations point 171, for 22 coal-fired power companies and the city's 11 coal production (including coal washing) enterprises in high frequency sampling.

Furniture, printing and dyeing, filling stations and other industries, focusing on pollution VOCs special inspection work, check the company focused on source control, process management, end of treatment, the treatment facilities to ensure the normal operation of equipment, environmental protection do not have the processing power of enterprise firm shall be eliminated by shutting down.

How to do a good job of dust prevention of gas-fired boiler!

The purpose of the air preheater at the tail of the gas-fired boiler is to restore the heat of the flue gas, which can improve the efficiency of the gas-fired boiler. When the gas is sent to the chimney, the temperature is lowered, thus simplifying the design of the pipe. It also controls the temperature of the gas. The air preheater at the rear of a gas-fired boiler is located at the bottom of a gas-fired boiler.
