In hot water boiler, how to prevent back-chamber tube plate crack?

Tubesheet before back to the combustion chamber the boiler work in three backhaul usage worst site, a long period of high and low temperature thermal stress, likely to cause the tube end thermal fatigue cracking, is where this configuration the boiler is the most prone to problems.

First, at this stage, gas boiler water treatment problems 1. boiler water treatment work is inseparable from lack of attention to industrial boiler equipment, but in many of the user site, we found that many boiler operators do not pay attention to the boiler water treatment, sewage and also regularly carry out checks, there is a large degree of danger. The main reason for this phenomenon is harmful to business managers and staff did not realize that not treat boiler water, over time, will produce boiler scaling, corrosion and other problems. 2. boiler water treatment method is not correct in the actual production and living, the boiler is used to contain a wide variety of liquid. But some staff do not know that for different kinds of liquids what action should be taken; some companies using a simple boiler water treatment equipment. These factors can pose a security risk to the boiler, resulting in security incidents. 3. Staff overall quality is not high and some staff members did not follow the rules and regulations of boiler water for testing. In addition, there are a number of operators of professional quality is not high, so that work is not high efficiency boiler water treatment, resulting in the deviation of the test results. There are even some staff members will laboratory data on fraud to fool the upper management.

Then, gas consumption gas boiler or oil-fired boiler of how to calculate it?

1, it is determined boiler output: output one ton boiler 600,000 kcal, and so, the gas boiler 4 tons output is 240 million kcal, output 10 tons of gas boiler 600 million kcal.

2, the heat value of the fuel is determined: the heat value of natural gas is generally 8400 kcal per cubic meter, diesel calorific value is 10240 kcal per kg.

3, the thermal efficiency of the boiler is determined: the thermal efficiency is determined by the area of ​​the heating boiler.

4, the calculated fuel consumption: fuel consumption efficiency of the boiler heat output = ÷ ÷ boiler fuel heating value.

Anyang City Children's Welfare Institute, director of the other fast condolences Group thanked welfare Xiqianxinzhi just for my company still insisted to visit the children feel very warm and happy. Fang Group, as a caring corporate fast, for five consecutive years of uninterrupted adhere to visit the orphanage children, and brought them all kinds of necessities and school supplies to children's lives to bring a dash of color.
