best quality electric hot water boiler
The basic characteristics of Henan Henan gas best quality electric hot water boiler gas boiler used before use, you must first understand some basic features on the boiler used. Henan gas boiler can well adapt to low oxygen combustion, while its air coefficient is smaller than coal and oil. Burner means disposed substantially as long as a suitable and properly adjusted combustion, as long as the excess air factor slightly larger than 1 which can ensure complete combustion. Flammable and rapid combustion, the flame length is short compared to the crude oil boiler. It explains the heat transfer effect from the combustion gas heat transfer point of view, because of its solid content of fly ash and flue gas carbon black particles is very low, thus forming a weak radiative heat transfer. While high water vapor content in flue gas, triatomic gas formed strong radiation. The degree of contamination and fouling Henan gas boiler heating surface to reduce the heat transfer effect is enhanced. And because the calorific value gaseous fuel quite different from 12000kJ / m3 to 12500kJ / m3, and therefore the size of the furnace or furnace can not be compared with oil-fired boiler, but also some differences between different gas fuels. Since the gaseous fuel in hydrogen content than coal, fuel oil is much higher, the higher the water vapor content of the post-combustion flue gas. Failure to take technical measures to recover the latent heat of vaporization of water vapor in the flue gas, the thermal efficiency of the boiler will substantial improvement. Due to the higher water vapor content of the flue gas, so the gas boiler low load operation is easy to produce the tail condensation of water vapor, resulting in low water pressure or flue element at the reservoir, the refractory insulation material is wetted and failure. While also easily lead to corrosion of the metal, and even affect the normal operation of the boiler. Due to easily form explosive gas gaseous fuel and air mixing in a certain ratio, the gas flame furnace fuel leakage or human combustion chamber has caused a risk of explosion, so the use of high safety requirements in Henan gas boiler. For example, next to the boiler, gas pipeline leak detection have a special need; 1. ensure safe ventilation of the boiler; 2. Electric Explosion done in place; 3, especially the preparatory work before the start of the boiler must be in strict accordance with the procedures and controls safety requirements saver purge the residual gas in the furnace. Since the gaseous fuel ash, sulfur and nitrogen content relative to the coal, oil must be low, the content of suspended solids in the combustion products is very low, and carbon dioxide. Hypoxia taken combustion, oxides of nitrogen formed by combustion (NOx) small amount, and for inhibition (NOx) generation amount of nitrogen oxides a high temperature is also easier to implement than other fuels. Therefore, Henan gas boiler to meet more stringent environmental requirements.
The system mainly composed of Shandong Shandong gas best quality electric hot water boiler gas boiler has now become the main lot cell equipment, schools, hot water heating, has the advantage of short heating to a temperature depending on the use and characteristics of highly stable gas boiler Shandong such devices, and Shandong gas boiler manufacturers for the sale of the control is relatively strict, let's look at the main gas boiler system Shandong composition: 1 air supply system Shandong gas-fired boiler air supply system is a more important part, because the gas in the combustion the process requires a certain amount of oxygen can guarantee full combustion of gas, so the air supply system has its own throttle controller, fan motor and fan and other parts, also in strategic locations and connected to the monitoring system to ensure timely delivery of understanding air system operating conditions; 2. ignition system according to another group of Shandong gas boiler system for the ignition system, ignition system object exists mainly in order to ignite the fuel, the ignition system comprising ignition transformers, ignition electrodes and the like, and to the electrical steps must arrange fire personnel hand Moving operation, Shandong gas boiler in order to protect security so using a manual procedure to complete the ignition operation; 3 monitoring system Shandong gas boiler also uses a monitoring system, in order to ensure that the process gas boiler operation, the air pressure, temperature real-time monitoring, when something goes wrong the first time it is possible to cut off the power supply startup protection and warning procedures to improve the safety performance of Shandong gas boiler operation, the monitoring system is a safety factor of gas-fired boiler system infrastructure upgrade; Shandong gas boiler is not only the air supply system , ignition system and monitoring system also includes a fuel system and electric control system, so this system is the basis of the five gas-fired boiler system is also essential systems. In the process of using the gas boiler in Shandong we should also pay attention to its maintenance, Shandong, use and maintenance of the gas boiler is also relatively easy way, can effectively reduce the workload and long working staff.
2019, Nanjing for more stringent ozone pollution, for volatile organic compounds, governance and control measures nitrogen oxides unabated.
Nanjing Ecological Environment Agency staff members at atmospheric introduction, with the recent temperature increases, there has been a trend in some parts of ozone exceeded. This summer, the environmental protection department will introduce stricter air pollution control measures, starting from the two aspects of governance volatile organic compounds and nitrogen oxides to reduce ozone pollution.
It is understood that Nanjing will be completed this year 44 companies VOCs governance and thermal power, cement, bricks and other building materials industries fugitive emissions-depth treatment in the city in batches with a gas-fired boiler 936 units, the implementation of the nitrogen oxides governance Sector Engineering; city station 475 to achieve ultra-low emission particulate biomass boilers, for the privately polluting fuels blended biomass boilers embodiment eliminated. It is worth mentioning that the revised "Nanjing Atmospheric Pollution Prevention Act," to be implemented next month. Among them, organic solvents, paints use, as well as volatile organic compounds corporate governance and management have put forward new demands.
1 ton gas best quality electric hot water boiler running on natural gas cost calculation users in the purchase of boiler equipment, in addition to considering the quality and price of the boiler, operating costs are also most concerned about. As a large industrial boilers special equipment, operating costs after start-up is not low. Today, small series to calculate the running costs of natural gas boiler, to help you better understand the gas boiler. On the whole, operating costs including natural gas boiler: fuel costs, utilities, labor costs, maintenance costs. Run 1 ton gas steam boiler 1 hour example to calculate the cost of running the boiler. 1, the cost of gas, 1 tons of gas steam boiler steam rated the amount of 1 ton / hour, different in different parts of the integrated natural gas quality and other factors, natural gas consumption in the 70-80 cubic meters / hour, according to our understanding, now on the market of natural gas the price of 3.5 yuan / cubic calculated (prices slightly floating), gas consumption is calculated according to 75 cubic meters. Gas Cost: 1 × 75 × 3.5 = 262.5 / hour 2, the cost of water, gas steam boiler 1 tons an hour to convert 1 ton 1 ton of steam into the water, because the middle of demineralized water and sewage water treatment needs, 1 ton of normal use of the steam boiler takes about 1.1 tons of water, according to our understanding, the market price is now floating around 3 yuan / ton. The cost of water: 1.1 × 3 = 3.3 yuan / hour 3, the cost of electricity, the main fuel gas steam boiler 1 ton electric burner position and pumps, other mostly weak. Burner using power 1.5KW, use the pump power of 1.4KW, other weak power use of about 1KW. During normal use of the boiler, electrical power is 0.65 times the full load power, calculate the total electric power (1.5KW + 1.4KW + 1KW) × 0.65 = 2.535KW. The electricity is $ 1 / calculation. Electricity costs: 2.535 × 1 = 2.535 / hour 4, labor costs, fast boiler into gas boiler market is the intelligent automatic high boiler plant, only coal fireman who patrol back and forth without the need to manually add fuel high intensity work. Fireman who according to 3000 yuan / month wage, working 12 hours a day, in two shifts. Labor costs: 3000 × 2 times / 30 days / 24 h = 8.33 yuan / 5 hours, gas boilers, and maintenance costs of model SZS fast WNS square type gas boiler in the factory after the quenching treatment and a full range of testing, failure rate Very low, response, post-boiler maintenance costs are reduced. If it is a gas station one ton steam boiler, the maintenance cost is about 2000 a year on it. According to 365 days a year, eight hours a day of computing time, the boiler operation cost per hour is: 2000/365/8 = 0.68 yuan. Combining these five aspects of the cost of inputs, it can be summed up 1 ton operating cost per hour of gas boilers: 262.5 yuan / hour + 3.3 yuan / hour +2.535 yuan / hour +8.33 yuan / hour +0.68 yuan / hour = 277.345 yuan / hour . In addition Xiao Bian also like to remind you that the above calculations are based on the cost of using boiler operating at full capacity, but due to the use of the boiler boiler enterprises have different needs, it may not be fixed to keep running at full capacity. Therefore, some of the actual running costs of the boiler than it is now calculated 277.345 yuan low.
