High efficiency and low stress horizontal internal combustion gas (oil) boiler


High and low stress horizontal internal combustion (oil) gas condensing boiler, break through the traditional horizontal internal combustion gas (oil) international popular three return, support flat tube plate structure, with modern design means, innovative thinking, research and design of ontology, return two arched tube plate, low stress, with separate condensing the thread smoke tube replacement technology and innovative products.


The double return of the flue gas in the shell of the boiler (the first return - furnace gall; the second return - threaded pipe), the arched tube plate and the arched rear plate. The arch tube plate and the arched rear plate can cancel the connecting piece, increase the repair space inside the shell, reduce the welding process and reduce the thermal stress of the weld pipe (because the rigid structure becomes a quasi elastic structure).


Horizontal condensation tube thread smoke - exhaust gas temperature from 100 DEG C, pipe inner wall of flue gas water vapor condensation, the flue gas heat transfer coefficient increase, reduce the heating surface, in addition, a small part in the recovery of the latent heat of vaporization, steel consumption under the premise does not increase, the thermal efficiency is improved to 95%.


High efficiency low stress condensing horizontal internal combustion gas boiler has the following characteristics:


1. High efficiency


The boiler adopts high efficiency heat transfer thread smoke tube, with low temperature flue gas heat recovery thread smoke tube, classification of scientific and rational utilization of flue gas heat, the boiler can be in the zone of high efficiency under different operating conditions were: rated load thermal efficiency of 95%, 75% of the rated load (normal load) tube operation in the thread smoke flue gas condensation state next, the thermal efficiency can be increased to 96%~97%, while the traditional three return structure about 90%.


Two, low stress


The finite element design, the body adopts the arched tube plate, offset furnace, the combustion chamber, and the thread smoke tube, with flexible matched waveform furnace, cancel the large straight brace, oblique bracing, the whole boiler from the traditional rigid high stress structure into quasi elastic model low stress structure. The safety and reliability of the boiler have been improved and the service life of the boiler has been prolonged. And the overhaul space in the pan shell is obviously increased.


Three. The structure is simple, easy to make and easy to repair.


The simple structure, increasing the space in the pot, greatly simplifying the boiler manufacturing process, making the maintenance more convenient.


Four. Improve the reliability of the cooling high temperature pipe board


The hot water type adopts the measures of cooling high temperature tube plate with backwater to improve the working state of the high temperature tube plate area and enhance the safety and reliability of the high temperature pipe plate.


Five. Low humidity of steam water separation in horizontal flow


The steam type adopts horizontal flow and steam water separation, which simplifies the structure of steam and water separation, and can get low moisture and high quality steam (humidity is less than 1%, while the standard regulation is no more than 4%).
