horizontal pellet boiler for sale

The price of steam horizontal pellet boiler for sale will be affected by many factors, including the price of the boiler body, the price of auxiliary machine parts, and the cost of boiler transportation.

In recent years, as people's growing awareness of environmental protection, the State also intended to promulgate stringent emission standards for nitrogen oxides. This horizontal pellet boiler for sale companies made a mandatory requirement - how to effectively reduce nitrogen oxide content in the boiler flue gas. Therefore, a focus on emissions of nitrogen oxides environmental revolution is quietly boiler industry. But for domestic boilers companies this road is not good to go, because the difficulty of controlling nitrogen oxides and more demanding of the boiler, every 1 mg / cubic meter of emissions control will cause the boiler costs dramatically.

There are causes of corrosion of hot water horizontal pellet boiler for sale hot water boiler which causes corrosion occurs What? Hot water boiler as a special equipment, long-term operation in a complex environment of high temperature, water vapor, etc., plus the process defects itself boiler design, manufacture, making the boiler in use are vulnerable to corrosion, affecting the normal life of the boiler . Therefore, to do the work of maintenance and corrosion hot water boilers, hot water boilers can extend the usage time, reduce operating costs. A relatively large amount of water supply hot water boiler operation, the boiler can not disclose the amount of more than 1% of the total water capacity of the boiler, if more than 1% boiler efficiency will be affected, so the process of boiler operation need to increase the fill water. If excessive leaking boiler, fill water increases to a certain extent, leading to an increase in internal boiler dissolved oxygen, dissolved oxygen and chemical oxidation of iron boiler equipment occurs, the boiler will rust and other issues. A college has two model DZL2.801.0 / 115/70-APW and AZL4.2-0.7 / 95/70-APW hot water boilers, as winter heating equipment. The device runs three years later found that water wall tubes appear upset, crossover phenomenon through after simple maintenance, this problem still occurs. Then inspection of the hot water boiler, the discharge 7,9 found innermost root left the furnace wall tubes permeation tube, which tubes 9 severe cracks, 10, 11 inside the far right of most of the waterwall tubes 12, 13 bleeds through the root canal, wherein the first pipe 12 of corrosion pore, pore size 8mm, other orifices each tube penetration occurs, a large number of red rust and black skin contaminants found by examining the inner drum. Acquisition and analysis, rust and dirt found in the drum component is Fe3O4 and FeO and the like. Low pH circulating water according to state regulations, the pH of the hot water boiler circulating water is controlled in the range of 10 to 12, will not cause metal corrosion phenomenon, if it is above or below this range, corrosion phenomenon occurs. Hot water boiler water temperature is generally around 95 deg.] C, if the fill water increases, the water temperature drops, pH value of the water may increase, resulting in hydrogen ion concentration in water do not meet the requirements of the hydrogen ion concentration of the heating system, then hot water boiler metallic surface form a protective film to protect the hot water boiler equipment. If the pH of the circulating water is low, the hydrogen ion concentration is lower than the hydrogen ion concentration of the water heating system required, then the metal will further exacerbate the oxidation reaction, leading to corrosion phenomena. Boiler water flow rate too quickly during operation, if the flow rate of the hot water boiler too fast or too slow will affect the normal operation of the boiler. When the flow rate of hot water boiler is greater than 10m / s, the diffusion rate of materials is exacerbated in water, the corrosion rate is further increased boiler plant; when the water flow rate is less than 0.2m / s, in the middle of the gas boiler will result in overflow of , and attached to the metal wall, the metal corrosion rate increased. Meanwhile, since the water flow rate is too slow, impurities in the water will be deposited in the boiler and the surface of microorganisms, and bubbles formed in the metal wall.

2, maintenance

Any machine in the process of using them requires a professional to do maintenance work, especially for the usual cleaning various parts inside the boiler and machinery, dust removal work must be done, otherwise the impact of the first addition is to affect is beautiful to the normal operation of the machine, while the impact of the work is likely to be hazardous to people's health.
