Manufacturers of burners for hydrogen production converters and preheated air systems
Thread Content
May I ask which are the manufacturers of burners and preheated air for hydrogen production converters?
We are using burners from Sichuan Aipu (top-fired type), and their performance is quite good

Top-fired conversion furnace burners: Luoyang Ruichang, Hubei Jixiang, Beijing Shenwu Thermal Energy Technology Co., Ltd. Many manufacturers produce hydrogen production units with small-scale air preheaters.
Our company is a manufacturer of heating furnaces, and we generally use Luoyang Ruichang and Hunan Jixiang burners, which offer good quality. The air preheater can be a heat pipe air preheater manufactured by Dalian Entropy Development Heat Transfer Technology Co., Ltd.; you can contact them at lyfwym@163.com
Our company’s 1 million-ton natural gas methanol plant uses plate-type air preheaters imported from the United States. The pressure drop and temperature levels do not meet the design specifications. When the plant was put into operation in July of this year, at 70% load, the pressure drop on the air side reached 2100 Pa (the design value being 1100 Pa), while the pressure drop on the flue gas side reached 2000 Pa (the design value being 1500 Pa). The exhaust fan reached its maximum speed at 75% load, and it is no longer possible to increase the load any further. The flue gas exit temperature is above 240 degrees. Could everyone please help analyze this? Thank you
The products of Jiangyin Petrochemical Power Equipment Company are of good quality, and the prices as well as the service are both reliable.
We’re using MECS products right now, and there are tons of problems. The technical staff and service personnel from MECS don’t have any intention of solving these issues – so stop lying. There are indeed problems with the product quality of MECS. I hope everyone won’t fall for scams in the pursuit of cheap prices.
Agreed; during operation, the pressure drop of the plate preheater increases significantly. During maintenance, when the plate exchanger was opened, it was found that there was a lot of flocculent debris attached to the fins; this was likely caused by impurities in the air that had accumulated over time through adsorption. Later, several nozzles were added above the plate heat exchanger preheater, and fresh water was supplied externally to regularly flush the finned tubes, with good results.
Is it cleaned online? Does it have a significant impact on production? What is done with the water used for rinsing? Is the water used for rinsing warm or cold?
