WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
A simple mathematical proof that, based on Fry’s equation, boiler efficiency at the grate limit is exactly half the maximum efficiency, is as follows:. Fry’s Equation: E b = k 1 – k 2 x M/G, where:. E b = Boiler Efficiency; M = Firing Rate; G = Grate Area; k 1 = predicted boiler efficiency at zero firing rate; k 2 = the slope of the graph relating boiler efficiency to firing rate.
FIXED GRATE. The fixed grate combustion system is a very simple and effective system, and it is widespread in certain applications due to its reliability and robustness. At INNERGY we have more than 50 years of experience designing, manufacturing and commissioning combustion systems for a wide variety of fuels, among which we find different types of conventional biomass, complex biomass and …
Moving-grate incineration requires that the grate be able to move the waste from the combustion chamber to allow for an effective and complete combustion. A single incineration plant is able to process thirty-five metric tons of waste per hour of treatment. The MSW for a …
The boiler vessel is a two pass hybrid design incorporating a water tubed boiler-type water membrane and a two-pass fire tube scotch marine vessel. The Hybrid RG design is suitable for applications to produce high pressure steam or hot water in ranges from 3,450 - 60,000 lbs/hr (3.4 mm BTU - 60 mm BTU) output from 100 up to 900 PSI.
The grate adopts horizontal type fixed grate, equipped with F.D. fan and I.D. fan for mechanical ventilation, and implements automatic water supply, alarm of high and low water level, interlocking of limit water level and over-pressure stopping.
For coal fired boiler,one is chain grate boiler which is automatic feeding fuel ;one needs labour to feed fuel is fixed grate boiler ;one is reciprocating grate boiler which is suitable for very high moisture fuel.When you put wood ,charcoal into boiler and require small capacity boiler,you can choose fixed grate boiler,it is manual feeding and
The boiler system has perfect automatic control measures, accurate oil temperature control, there are multiple control and protection for oil temperature, pressure and flue gas over-temperature setting, ensure safe and reliable operation of the hot oil system. Vertical Fixed Grate Biomass Fired Thermal Oil Boiler. Rated thermal power. kw
Sitong Boiler have developed a fixed grate, moving grate, chain grate and chamber combustion four combustion modes, and three body structure: horizontal pipe, single longitudinal, vertical longitudinal. Different from coal-fired boiler structures, the main features of biomass fuel boiler are as follows :
