gas fired hot water boiler 100kw 400kw price

Type action and atmospheric pressure fired hot water boiler 100kw 400kw price hot water boiler, the boiler is used for hot water production, is the heat released by burning the fuel, or some other thermal energy to heat the water, so the water can reach a temperature a certain temperature, so that it is a kind of energy equipment, pressure hot water boiler, which generally have electric hot water boilers, hot water boiler fuel, gas hot water boiler and a gas hot water boiler. The role of hot water boiler, there are two heating and bathing. . Boiler water pressure hot water boiler operating rules, must first go through softening job. When the boiler is enabled, open the pipeline, so that the boiler is full of water. When shutdown, the pump can not be stopped immediately, to wait until after the boiler outlet water temperature dropped to 50 ℃, to be able to stop the pump. Check instruments and the like is normal, the power switch, the control cabinet can be illuminated normal power indicator. Boiler operation, the operator should comply with the provisions of the system, and make the record job. Boiler during start-up, it should start circulating pump, circulating water run until normal before we can increase the oven temperature. When you press the run button, boiler pump can start working, running lights can light up.

The reason for the low nitrogen boiler What are reasons for the low nitrogen boiler has what? Coal is a major component of China's energy, coal consumption accounts for about 76% of primary energy consumption. With the rapid economic development and the rapid increase in coal consumption, coal caused by air pollution is getting worse, especially coal-fired flue gas released nitrogen oxides (NOx) are major pollutants of air pollution one. Nitric nitrogen oxides can damage the ozone layer, changing the intensity of UV irradiated to the ground; also cause changes in the ozone layer climate change, which will affect the entire environment: air, nitrogen nitric oxide or an important source of acid rain, acid influence. In the environment it is widely known that the soil and water acidification, growth of crops; also demonstrated a number of human diseases are also generated directly related to the nitrogen oxide in the air of nitric oxide. In the fuel combustion process, NOx in the atmosphere dissolved in water will form acid rain, caused widespread damage to the environment caused by corrosion, damage and other open-air heritage buildings and industrial equipment huge economic losses. Damage to the plant resulted in the death of forests; fish and lakes death; destruction of crops and soil composition of the production loss, and even death; groundwater drinking is harmful to humans. Nitrogen oxides are also directly endanger human health. The higher the concentration of nitrogen oxides, the stronger the toxicity. Because it is easily combined with animal hemoglobin in the blood, causing blood to oxygen, causing paralysis of the central nervous system. When NOx is present ultraviolet radiation of the sun, automobile exhaust hydrocarbons, light blue form toxic compounds. Byproducts are City City primary air containing pollutants such as hydrocarbons and nitrogen oxides, it refers to the product of the solar radiation to produce specific chemical reaction and the resulting mixture mist. It makes the eyes, nose, lung and other organ damage, red eye, tears and other symptoms. Long-term chronic hazards can cause pulmonary dysfunction, bronchitis, and even the development of cancer. Severe cases can cause severe chest pain, nausea and vomiting, hand-foot discomfort, blood pressure, coma and even death. In recent years, large areas of severely affected by fog and haze, the lives of the people caused great pain. Many people mistakenly believe that only respirable particulate matter is the major cause of haze. In fact, another reason: nitrogen oxides can not be ignored.

Group multiple departments quality systems, technology department, production systems, development systems, with the assistance of outside experts, please, to overcome the difficulties, overtime, and fulfill all the preparatory work. Assessor staff often give up personal time off from work carried ASME study and training, frontline staff overtime for practical operation of the exercise. All those involved in the trial personnel in the company "professional life, work lean" under the guidance of the core values ​​of continuous fighting, the various problems couplet review group proposed were closed, one-time passed the ASME certification.

Oil-fired boiler technical analysis when equal sulfur content greater body oil and coal, low-temperature corrosion of boiler fuel in general is much more serious than a coal-fired boiler, for two main reasons: 1 coal-fired boilers, especially pulverized coal, coal 90% of the ash content of the flue gas is taken away, fumes generated in the sulfuric acid vapor is adsorbed fly ash in the flue gas, sulfuric acid vapor in the flue gas is reduced; coal combustion, about half of the sulfur remaining in the ash . While combustion of oil, the sulfur content of the fuel is almost complete conversion of SO2, the fuel ash few, little fly ash in the flue gas, the flue gas adsorption capacity of the sulfuric acid vapor is weak. 2. higher hydrogen content in the fuel, about 11% to 12%, per ton of fuel combustion can produce about one ton of water vapor, when the fuel in the flue gas water vapor partial pressure higher than when coal, lignite but because with water and more exceptions detailed in Table 1 below. When these two reasons that the fuel, the concentration of sulfuric acid vapor in the flue gas is large, when the sulfuric acid vapor in the flue gas is not only a so-called thermodynamic point of water vapor partial pressure is low is formed, as shown in Table 1. When the flue gas in a small amount of sulfuric acid vapor, the flue gas dew point of significantly increased. Effect of sulfuric acid concentration on the corrosion rate is large, typically at a sulfuric acid concentration of 40% to 50%, the fastest etching. Due to use of fuel oil-fired boiler, the flue gas dew point is not only high, but the sulfuric acid concentration in the air preheater heating surface is also formed large, low-temperature corrosion is worse than boiler fuel fired boilers.
