Henan normal shutdown gas boiler and a its security, Henan gas boiler water control MEASURES: ① alkalinity boiler water 6 ~ 26mmol / L② boiler water oxygen ≤0.1mg / L③ feedwater hardness ≤0.03mmol / L④ furnace PH value of water 10 to 120 two, Henan normal gas boiler shutdown: ① closing operation of the gas boiler Henan closed switch ② ③ inner drum natural gas pressure reduction valve the water level in the drum ④ ⑤ high water discharge check valve is closed tight ⑥ Close boiler pump valves! ⑦ off the power switch three different gas boiler safety Henan Henan other gas with a gas boiler, particularly its mounted position, large air consumption is high product safety requirements. So, in North America, all gas boiler products must detect all pushed through strict safety and environmental standards before the market. Testing standards with the development of products and constantly updated. Various types of boilers exact product has a corresponding special safety testing standards. The balance gas boiler and a flue gas boiler testing standards different decorative gas boiler and heating gas boiler with different standards. Therefore, the balance of North American gas boiler should have the certification of products, such as such as AnsiZ21.88 or CSA2.33, representing a safe and environmentally friendly products has reached the standard, users can be assured.

What are the conditions so that the boiler can burn fully as we all know, if the boiler combustion, can save a lot of fuel, and combustion efficiency and improve efficiency in the use of the boiler, you can save the cost. But in reality there are boiler combustion process is not fully burn, so what conditions the boiler can burn it fully? Because burning is a complex physical and chemical processes, combustion speed depending on the chemical reaction of fuel and oxygen as well as oxygen and speed contacting and mixing speed combustibles. (Combustion speed per unit time reflects the number of burning off the combustible material.) The former is called the chemical reaction, also known as chemical conditions; the latter is called a physical mixing speed, also referred to as physical conditions. Only in the case of chemical conditions and physical conditions are more compatible in order to obtain a faster burning speed. Combustion is possible to sufficiently and quickly conditions are: (1) relatively high furnace temperature, the temperature of the chemical reaction is the basic condition of combustion. It fuels the fire, combustion stability and burnout have a great impact. Maintain the proper temperature in the furnace is very important. Of course, when the furnace temperature is too high, consider the problem of slagging boilers. (2) a sufficient amount of air supply air supply to provide sufficient oxygen for the fuel, which is the initial condition of the combustion reaction. If the air supply is insufficient, the fuel can not get enough oxygen, you can not achieve complete combustion. However, excessive amounts of air will cause the furnace temperature to decrease and increase the exhaust loss. (3) good mixing conditions, sufficient air to provide sufficient oxygen to supply the fuel, which is the initial condition of the combustion reaction. If the air supply is insufficient, the fuel can not get enough oxygen, you can not achieve complete combustion. However, excessive amounts of air will cause the furnace temperature to decrease and increase the exhaust loss. (4) a sufficient time to burn the fuel in the furnace for a time sufficient to achieve a high burn-up fuel, which is a sufficiently large furnace volume. Proportional to the volume of the furnace and boiler capacity. Of course, also related to the volume of the furnace with the combustion characteristics of the fuel. For easy to burn the fuel, a relatively small volume of the furnace. For example, for the same capacity furnace boiler fuel burner furnace volume smaller than the volume of the pulverized coal, and smokeless coal furnace volume dispersion furnace volume slightly larger than the cigarette coal stove.

2.8 MW WNS gas-fired hot water boiler for agricultural parkShanghai Sunqiao Modern Agricultural Park is the first comprehensive modern agricultural development zone in the country. There are more than 60 enterprises in the park and seed seedlings, facilities agriculture, deep processing of agricultural products, greenhouse manufacturing, biotechnology, leisure tourism and popular science, these six leading industries have been formed. The park has a planned area of 4 square kilometers. The person in charge of the park has divided a boiler room area for centralized heating according to its superior geographical location. In recent years, Shanghai has taken the leading work of replacing coal-fired boilers by clean energy boilers. Sunqiao Modern Agricultural Park is located in the Pudong New Area, a national sanitary city. From the perspective of environmental protection, priority is given to gas boilers. Through the intense bidding campaign, two WNS gas-fired hot water boilers of ZOZEN boiler were successfully selected to provide a fast heating, low noise, dust-free heating water environment for Sunqiao Modern Agriculture Park.
