steam boiler company list

3, product quality varies greatly

Pressure hot water boiler manufacturing industry is developing rapidly, the situation of supply exceeding demand gradually appearing on the market, it inspired some manufacturers lower prices vicious bad guide; some manufacturers and weak technical force, poor manufacturing quality, even cut corners, gave boiler had a negative impact.

Incorrect operation of steam boiler company lists and leaking how to do? Most of the steam boiler with a certain pressure, high-temperature steam can be output at the same time heating the water, belong to special pressure equipment clearly defined our country, and the implementation of specific practices. Whether the operation meets the requirements will directly affect the life of the boiler, which is why some steam boiler service life is very short, but others can achieve long service life. When incorrect operation of steam boilers and leaking, do not panic, we can save. First, a cause, there is no oxygen to the boiler feed water of high oxygen content resulting in oxygen evolution boiler operation cause corrosion in the gas accumulation space. 2, improper daily operation, a shutdown did not close the valve when the steam valve or the main pipe, air into the furnace, so that when using the boost again, did not exclude the entry of oxygen, so that in a hot and humid environment caused by oxygen long-term corrosion perforation of the smoke pipe. Second, the standard operation 1, boiler feed water in accordance with standard GB1576-2008 oxygen, reduce the oxygen content. 2, during shutdown, a shutdown while the boiler is in the normal high water level and normal pressure, and then close the inlet valve and the main valve, to prevent intrusion of outside air oven. 3, when the furnace is first started slightly open the main exhaust valve until the pressure reaches 0.1-0.15MPa closing the main valve to eliminate air furnace, and then open the main valve when the air supply to the rated pressure. 4, strengthen valve maintenance, maintaining rigor.

When the water in the steam load boiler evaporation, steam pressure rises; when the steam load is less than the amount of evaporation, the vapor pressure is decreased. Adjustment of steam for evaporation is adjusted, and the amount of evaporation in turn depends on the size of the boiler combustion conditions, thus reflecting the change in vapor pressure balance between the load and the combustion boiler. When enhanced combustion, evaporation is increased; when the combustion reduced, evaporation is reduced. Therefore, when the load increases, should first strengthen the wind, and then increase the air supply and fuel, enhanced combustion; when the load is reduced, should reduce fuel and reduce air, thus weakening burn, do so relatively safe, but also boiler steam pressure to maintain stability. High pressure hot water boilers, hot water boilers increase in the components subjected to stress, likely to cause damage or affect life expectancy. Especially when the vapor pressure is too high and boiler safety valve without action, explosion prone to accidents. Even if the steam pressure is increased to cause the safety valve, the steam will escape from the safety valve will cause greater heat loss and affect the performance of the safety valve closed.

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 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.
