Electric heating normal pressure hot water boiler
The basic characteristics of Henan Henan gas electric heating normal pressure 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.
Electric electric heating normal pressure hot water boiler requirements for electric boilers for water main applications where large areas of hotels, restaurants, colleges, factories, etc., in its work, after a long time the surface or internal scale phenomenon occurs, this phenomenon greatly affect the equipment, the following it'll tell you about cleaning method: 1, acid cleaning method: ① this pickling solution can not only clean up the boiler scale (except when nitrates scale, add hydrofluoric acid), and very little corrosion gas hot water boiler. ② descaling pickling process using hydrochloric acid or nitric acid, most of the cleaning. Pickling solution by adding nitric acid or hydrochloric acid was added inhibitor of the corrosion inhibitor composition. 2, the mechanical descaling method: when the electric furnace with a loose boiler scale and slag, so that the cast iron hot water boiler shutdown cooling, boiler water let go of, after washing with water, can be used flat shovel, wire brushes, and a motor milling descaling header. 3, alkali cooking cleaning law: ① alkali cooking method is simple, relatively small side effects. ② alkali cooking method of cleaning descaling, pickling cleaning effect than the difference method, but since a base boiled loose scale, so it is difficult for, may be a cooking method I with a base with hydrochloric acid cleaned scale before acid pickling deal with. Scale electric boiler efficiency is an important factor in the life and influence, in order to ensure it is safe to run the economy, the need for a reasonable scale clean-up work, so essential to get rid of scale, reduce equipment failure and reduce damage.
Gas electric heating normal pressure hot water boiler efficiency exhibited high energy in the energy-saving high-efficiency two gas boilers have shown that the two aspects of its electrical system will automatically enters the automatic operating state, on the one hand: after the operation switch is pressed gas boiler . Equipment safety equipment starts, the circuit gas-fired boilers will appear short circuit, leakage, water, etc. will automatically alarm and trip. More safe and efficient! Unlike gas-fired boiler gas boiler, like, on the one hand is the gas boiler can be electrically controlled system. It not only more environmentally friendly, energy-saving, the most used boilers. Gas boiler electric system can be automated operation, control and peace. Mainly reflected in two aspects. Are concentrated in a computer control panel of gas boiler is running, the time required to replace water, electricity connection, it should be ready for gas it can control any indication can be through the operation of the electric system its operation, eliminating the need for labor and fuel waste.
A comprehensive national response to reduce air pollution, gradually increasing the intensity of environmental protection policies in recent years, Inner Mongolia has been committed Bayannaoer ban small coal-fired electric heating normal pressure hot water boilers to reduce environmental pollution and improve urban air quality of the environment. According to government-led, departmental interaction of the implementation of the principles, date, a total of 295 units Bayannao'er 10 tons of steam coal-fired boilers and all removed, and replace the use of cleaner natural gas, biomass as a boiler fuel, which after the boiler put into use, it can function properly, the monitoring indicators in line with "boiler air pollutant emission standards."
A total ban on coal-fired boilers is an important measure to improve the quality of atmospheric environment, after Bayannao'er implementation of the "Action Blue Sky" program, in accordance with the chimney fell to the ground, boilers shift, clear standards of raw materials, since 2013, the city's 10 tons of steam All of the following coal-fired boilers complete ban eliminated, replaced by natural gas, biomass, air and other clean energy. For natural gas pipeline network built-up area is not covered within the scope of the coal-fired boilers, an alternative implementation of electrical, solar air heat sources such as comprehensive transformation.
