Hot water boiler Wns series of horizontal internal combustion boiler is the boiler hull type horizontal tri-backhauling internal combustion boiler designed by our technical professionals according to the advanced technology home and abroad, combined with practical experience. The boiler is fully automatic, the fuel after atomization by the burner forms the flame filling the whole waveform furnace, and via furnace wall to transfer the radiant heat, this is the first backhauling. The high temperature smog yields from combustion is concentrated in back combustion chamber and turns to the second backhauling, such as whorl flue pipe bundle area; after heat exchange by convection, the smog temperature gradually lowers and goes into the front smog chest, and then turns to the third backhauling, for example, bare pipe bundle area, and then passes through rear smog chest to chimney, and finally exhausts to the atmosphere. This series of steam boilers can greatly promote the boiler's efficiency, save fuel and lower the operation cost, so as to reach the aim of high performance, gas saving and safety of the boiler. The said products passed the pyrological test from shanghai industrial boiler's research institute and the environment protection test from shanghai dust equipment inspection center under national environment protection bureau, that every performance target reaches the design requirement and totally in line with the national standard, and also passed the specialists' certification from jiangsu province machinery industry bureau. The product is unanimously believed to hit the advanced level home and abroad

Hot water boiler
3-pass system 0-16 bar working capacity low cost flue gas emulsions Minimum utilization efficiency Patented special burner design in solid fuels
Anti burnback feeding system: pellets feeding system adopt double stage screw feed. The first stage is for controlling the pellet feeding quantity to make sure enough pellet fuel. The second stage makes sure there is no excess pellet in the feed screw. So it is blank between the first stage and the second stage. There is no back-fire happen and make sure the safety operation. Through reducing the load of feeding system, the wood pellet boilers feeding device will have fewer fault. Intelligent control: we adopt microcomputer one-button operation, automatic feed automatic ignition, with the setting temperature, start and stop cycle, and fault alarm function, simple and easy operation. Advanced combustion system: adopt patent inside wood pellet burner, adopt special three side air supply system, which makes sure the pellet full combustion. Equipped heat recovery device makes the boiler efficiency can reach 92%. Safety operation: anti-back fire feeding system, temperature sensor, low water level protection device, over-temperature protection device. Easy to maintain: wood pellet hot water boilers belong to atmosphere hot water boilers. There is no need for professional stoker. It is automatic wood pellets feeding and automatic ignition. User just needs to add 1-2 times fuel per day. Ash cleaning is very easy, user just needs to take out of the ash bucket at the bottom of the chamber. Cost saving: wood pellet hot water boilers operation cost is just 1/3 of diesel oil hot water boilers and 1/5 electric heating hot water boilers.

Wns gas & oil fired hot water boilers are three pass wet pack, horizontal, smoke tube type( fire tube) fusion welded. Hot water boilers gas & oil fired are made to iso / ibr / asme code. These are available in capacity of 0.7mw. To 14mw. Components are engineered for maximum safety, highest efficiency, dependability and quit operation. Wet back models eliminate rear end refractory and its inherent maintenance cost, reduces stress of rear tube sheet and ligament cracking, radiant heat is eliminated, lengthening tube life and reducing heat loss from rear turn around. Wns gas & oil fired hot water boiler feature: 1. Fully wet - back design effectively absorbs radiant heat into the water, keeping tube ends and rear of coiler cooler than in dry back design. 2. Three passes extract maximum useable heat from the fuel. 3. Large , water - surrounded furnace tube assures complete combustion and heat absorption without flame impingement. Wns gas & oil fire tube boiler application Boiler suitable for bakery, pharmaceuticals &bulk drugs, beverages, dairy, fetilizers, processed food industry, textile industry, hospitals, hotels, investment precision casting industry, laundry, paints & varnishing industry, mineral water plant, yarns, etc TypeRated evaporation (mw)Rated steam pressure(mpa)Nominal steam temperature(c)Feed temperature(c)Heating area(m2)Water volume (m2) Wns0.7-1.0-y(q)0.71.09570293.1 Wns1.4-1.0-y(q)1.41.0957055.73.93 Wns2.1-1.0-y(q)2.11.0957078.844.8 Wns2.8-1.0-y(q)2.81.09570986.8 Wns4.2-1.25-y(q)4.21.259570141.79 Wns5.6-1.25-y(q)5.61.259570189.711.9 Wns7-1.25-y(q)71.25957024812.4 Note: here are some of specifications for your reference, and you can consult us for more details.
As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm. CFBC can desulfurize directly during the combustion process, and the desulfurization efficiency is high. The technology and equipment are simple and economic, and the costs of its initial investment and operation are much lower than those of dry pulverized coal furnace and flue gas desulfurization (PC+FCD). The discharged ash residue has good activity and is easy to be comprehensive utilized without secondary ash residue pollution. The load adjustment range is large, and the low load can be reduced to about 30% of the full load.
