china electric heating hot water boiler prices

Advantages: Low cost: the implementation of the pipeline, so that lower gas prices, fuel cost decreases; the model of high boiler combustion efficiency, fuel savings, investment buying low fuel costs; the whole side pull butt welds, boilers safe life long, low maintenance costs. High efficiency: flue gas condensation recovery tail arranged, can effectively control the exhaust gas temperature, high thermal efficiency of the boiler; using automatic burner, water continuous electric adjustment, high combustion efficiency.

Provide for the growers Kingenta Ecological Engineering Group, the main compound fertilizer, slow release fertilizer, water soluble fertilizer, bio-fertilizer, soil conditioner, etc. required for a full line of soil and - with another giant fertilizer industry enterprises farming solutions services. 2016, Kim Jong large group with my company, to buy one of two 10 tons of steam condensing steam boiler (WNS10-1.25-Y.Q). It is the product side were quick constant pursuit of quality, in-depth research and development of control and intelligent control, boiler energy efficiency as well as high demand for continuous improvement of energy efficiency and emissions, making the fertilizer industry's two leading companies invariably choose the fast way hand in hand!

The basic characteristics of Henan Henan gas 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.

In order to judge the quality of gas-fired boiler, the manufacturer must have a manufacturing license, and the manufacturer must also purchase the boiler product produced by the qualified manufacturer. At the same time, the strength calculation and structural design of gas-fired boiler are also examined. All gas-fired boilers are confined to pressure, while the liquid-phase furnaces of gas-fired boilers are divided into two types: pressure-bearing injection type and unconfined suction type. The component of organic heat carrier furnace should be calculated according to the current boiler strength calculation standard, and the design pressure of geotextile is 0.3 MPA for working pressure, and not less than 0.59 MPA. Second It is necessary to carry out pressure test on gas-fired boiler, when it is assembled in manufacturing unit, installed in service unit and repaired. In the case of electrically heated boiler, its pressure test is divided into hydraulic test, hydraulic test and gas tightness test. No matter the gas furnace or liquid furnace of the electric heating boiler, the hydraulic test should be carried out in the manufacturing unit, and only the hydraulic test should be carried out in the working unit, but the hydraulic test should not be carried out. For gas furnaces of electrically heated boilers, gas tightness tests should be carried out in manufacturing units and service units to check the sealing of non-welded joints. Gas-tight test methods and requirements for electrically heated boilers Proceed in accordance with the relevant provisions of the pressure vessel. Gas tightness tests are not required for liquid stoves of electrically heated boilers. At the same time, the welding quality of the electric heating boiler should be strictly controlled. Because the organic heat carrier of the electric heating boiler is easy to leak and burn, the welding requirement of the organic heat carrier furnace of the electric heating boiler is higher than that of the boiler with water as the medium. The welding quality of electric heating boiler should be strictly controlled.
