Development history of oil and gas industrial high efficiency condensing fired boilers

Oil and gas boilers appeared late, and oil was first used in boilers in the 1930s, when it was used as an auxiliary fuel in coal-fired chain grate boilers. Due to the poor quality of the combustion technology and the fuel at the time, accidents in which the fuel suddenly extinguished during combustion often occurred, and thus were not actually used.

6 ton industrial wood fired steam industrial high efficiency condensing fired boiler features:

1. Furnace and the two sides of burner zone adopts membrane water-cooled furnace structure. The membrane structure of wood fired steam boiler, our company’s solely design once used in electric boiler , is now applied in shaped assemble boiler. Its advantages lie in great thermal transmission heat, better heat transfer effect, lower heat loss ,better air impermeability, no wall distortion and no ash leakage.

2. The structure of arches adopts the newest technology --the upside”a” technology, which is awarded the national science and technology prize. The front arch is high and short while the back arch is low and long. And the part near the exit is inverse inclined type,while the front arch is 45ºinclined type, they together form a downside a flame structure,which makes the lean coal combustion easier and it can adjust itself to a wide rang of coal types. In this way, the flue gas is kept within the furnace a longer time, and the combustion efficiency is higher. The streamline shaped back arch can throw the non-burned carbon grains in the middle and back part of furnace to the front, so that the coal can be easier to be ignited and the ignition lines are tide.

3. The wood fired steam boiler adopts double layers or single layer layout structure, which can meet the customers’ requirements better.

1. oil and gas steam industrial high efficiency condensing fired boiler system

A complete gas boiler system mainly includes the boiler body, burner, control system and other auxiliary structures

Fangkuai Company has a fully-automatic PLC intelligent control system designed and developed by itself with complete intellectual property rights. It adopts a combination of mechatronic control equipment and a programmable logic controller (PLC). Take the advanced programmable logic controller (PLC) as the "central processing unit" of the control system. The control system is operated through the touch screen, which greatly improves the degree of automatic control and operation reliability of the industrial high efficiency condensing fired boiler, and the operation is simpler and more intuitive.
