Water Tube Double Drum Boiler


Water Tube Double Drum Boiler

Around at 10:12 on February 28, 2019, Zhangjiakou City Chabei Management District Kai Austrian Energy Management Services Ltd. Taiwan 15 tons of steam biomass water tube double drum boiler drum due to the control zone tearing a serious accident, killing three people the death of four people were injured.

Currently seven injured in hospital emergency treatment, cause of the accident is still under investigation, rehabilitation disposal is also an orderly manner.

Heartbreak is that similar incidents happened from the last time, only 28 days.

At 15:30 on January 2019 May 2009 55 points, Zhangjiakou City Hall Ltd. Hong Mei generating boiler scalding accident, three people were killed and one injured.

Boiler special equipment is clearly defined our country, whether it is manufacturing, purchase, installation, operation or maintenance, have strict operating guidelines. Now many have adopted new boiler intelligent control, operational safety compared to conventional boilers, more convenient; but that does not mean foolproof, vigilant and master the correct method of application, in order to minimize accidents frequency. After all, the cost of each accident are living lives.

Recalling these events boiler explosion

March 3, 2014, Xingtai City, Hebei Province, a steam boiler explosion. Boiler plant razed to the ground, surrounded by multi-family residential buildings, factories affected by the explosion were destroyed. According to the injured introduction, cause of the accident may be due to faulty boiler and pressure control instruments not work, the pressure continues to rise, leading to an explosion.

November 15, 2014, Wangcun Daiyue located in Tai'an City, congee shop offices under Daiyue Xiaoxiang Court Food Co. boiler explosion accident caused part of the building collapsed, the scene four different degrees of harm employees .

About 5 minutes, packaging wood factory near Jincheng territory of Huai'an City, Jiangsu Province, south of the village of Hope Town boiler explosion occurred at 9:00 on January 24, 2016.

February 28, 2016, after the city of Hebi in Henan Province Junxian Pi Mao Shan Street office building energy source of the village cents Ltd. boiler explosion occurred, resulting in many injuries and death.

May 12, 2016, hurt Fengxian Plastics Corporation boiler explosion occurred, resulting in many casualties.

For general type of steam water tube double drum boiler feed water hardness index it is very important, the level of boiler water hardness tends to affect fouling and corrosion problems later. If the gas boiler water boiler so that the boiler water hardness higher levels may occur due to evaporation scaling, hot water boilers and, relatively speaking, more susceptible to corrosion.

Natural water harmful impurities water tube double drum boiler and boiler water treatment purposes: natural water there is often a large amount of impurities, which affect the boiler are: suspended solids, colloidal material and dissolved substances. Suspended solids and sediment by the material cavity, and certain plant and animal remains low molecular weight aggregates, etc., are the main factors of the water was cloudy. If these impurities into the ion exchange resin to exchange contaminated, affecting the quality of the water directly into the boiler as {, worsen the quality of steam, dirt and easily deposited, clogging pipes, so that damage due to overheating the metal. Suspended solids and colloidal substances can be removed by pretreatment. Mainly refers to a substance dissolved salts dissolved in water and certain gases. Natural water, very pure even seemingly clear tap water contain various dissolved salts in which calcium and magnesium salts. That is the hardness of the material, it is causing a major source of boiler fouling. Due to the scale of great harm to the boiler, thus removing the hardness, the primary task is to prevent fouling of boiler water treatment, dosing treatment may be achieved by chemical treatment outside the pot or pan. Dissolved gas in the fuel gas boiler apparatus affecting mainly oxygen and carbon dioxide, which will generate oxygen boiler corrosion and acid corrosion, oxygen and hydrogen ions at the same time is also a larger effect of depolarizing agent, accelerate galvanic corrosion carried out, it is an important factor boiler corrosion. Dissolved oxygen may be added or removed by the deaerator reducing drugs and other methods. For carbon dioxide, boiler water remains constant as long as the pH and alkalinity, which influence can be eliminated.

4 large household electric water tube double drum boiler features 1, the overall configuration of the combustion system of the steam boiler and burner design as a whole, tailored in accordance with this boiler design features, our plant is tradition, the boiler combustion system to achieve the best ratio is the combination of energy-saving and environmental protection technology. 2, advanced automatic control using automatic control of microcomputer, an integrated automatic pressure control, fire detection, water protection, automatic alarm intelligent control, a key control fool a single button press to fully automate running, any security devices that are beginning to work, no special duty to make operators more peace of mind, peace of mind. 3, the structural design of safety science equipped with a safety valve, the multiple pressure controller, control and protection level and other devices chain protection, absolutely safe and reliable, the use of finned tube tubular furnace structure, to effectively compensate for thermal expansion, to prevent thermal expansion shrinkage stress is generated, the boiler structure, safety and reliability, extended service life. 4, high-quality steam fast Small water volume of large steam pit unique design can make you gain steam in the shortest possible time, the built-in steam-water separation device to ensure high-quality high dry steam.
