At present, the company has possessed steel seal and authorized certificate for power boiler (S) and pressure vessel (U, U2) issued by American society of Mechanical Engineers (ASME), national Class A boiler manufacture license, Class A1+A2 pressure vessel manufacture and design license issued by national quality inspection bureau, and German ISO 9001 quality management system authentication certificate. Besides, ZG Boiler also got IBR and ASME International Certification.

Economizer is Important

Studies have shown that over a 20 year period, 96% of the cost of operating a boiler system comes from fuel costs. Also, in a typical boiler system, 10% to 20% of energy input is lost in the form of heat escaping to the atmosphere. The installation of a boiler economizer helps to solve this problem. An economizer is a unit that captures heat from the stack, and then returns it to a water system. To determine if a boiler economizer is right for your facility, look at your annual boiler fuel bill and subtract 5 to 10% of the cost. If this is a significant number to you, then you should consider adding an economizer. The payback will have a direct impact on your bottom line. This is one of ZBG’s many products that help companies reduce overall energy consumption. And remember, fuel not burned equals exhaust gasses not emitted!

How do you know your boiler air preheater leakage is not it? Since the low-temperature air preheater of boiler corrosion and abrasion, easy preheater tube is perforated so that air leakage into the flue gas. In addition to visual inspection of the preheater after shutdown, the boiler can also be found at runtime preheater leakage. Preheater Air Leakage phenomenon are: (1) the excess air ratio than the normal standard preheater. (2) increase the current blower, reduced pressure preheater inlet and outlet. (3) the current induced draft fan increases because of the increased load induced draft fan. (4) severe air leakage, blower inlet damper fully open, the air flow is still insufficient, less than the rated boiler load. (5) a large number of cool air leakage into the flue gas, so that the exhaust gas temperature drops.

The safety inspection operations will be based on "regarding the development of boilers and industrial emergency notification equipment and facilities safety inspection of" (Wei Safety Office Zi [2019] No. 23) documentation requirements, earnestly implement the regulatory responsibility, and actively carry out arrangements, combined with Cravens practical, clear pressure boiler safety inspection work content and division of tasks.

In conjunction with the National Health City welcome the review investigation work, based on their job functions, all members of the team to take the sinking line, full package by, Division linkage approach, focusing on whether the boiler to handle the use of registration, whether periodic inspection, workers who whether induction certificate, the safety valves and pressure gauges and other safety accessories boilers are using the site regularly check verification, the highest level gauge whether there has been a minimum level of safety markings for verification. 54 boiler region's 24 units were one by one investigation. Up to now, all 33 units in the boiler are in an examination period, in line with the requirements. It has two boilers to handle the deregistration, and 19 boilers have long-term disabled, is now urging the use of units to seize deregistered.

While actively step up publicity and training efforts, and send more professionals to communities, cooperatives were the main person in charge of safety knowledge of professional training, to explain the basics of boiler and check focus, effective universal safety knowledge, improve regulatory efficiency.
