Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

Beginner's Guide to Biomass Boilers | Homebuildi

File Size: 1MB If we assume a heating demand of 20,000kWh per year – about the minimum for a biomass boiler – the running cost would be around £1,200 per year with an RHI return of around £1,350 per year. This is a ‘profit’ of around £150 per year for seven years.

The emissions from co-firing of biomass and torrefi

Oct 28, 2019· In this study, biomass of rice straw (RS) and wood (WD) and their torrefied biomass (RST and WDT) were used as solid biofuel (SBF) for co-firing individually with coal in a commercial continuous chain-grate steam boiler system, which was conducted at fixed input rate of heating value of mixture of SBF and coal and at fixed airflow rate.

Biomass Firing Boiler for Heating and Electrici

The biomass fuel encompasses a large variety of materials, including biomass pellet, wood, sawdust, bagasse, palm oil kernel, coconut shell, straws. Biomass firing boilers are the main equipment for heating and electricity generation. Chain grate system. Biomass fired chain grate boiler is used for heating and steam processes.

Biomass Co-firing - American Coal Counc

Co-firing coal with biomass is a potentially valuable tool to help decrease greenhouse gas and other emissions in coal-fueled boilers. Use of biomass at low to moderate biomass to coal ratios appears to produce the best performance enhancements and can result in overall life-cycle energy consumption reductions, as well as reduced solid waste generation.

Biomass & Wood Fuelled Heating | Energy Saving Tru

Wood-fuelled heating systems, also called biomass systems, burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers. A stove burns logs or pellets to heat a single room - and may be fitted with a back boiler to provide water heating as well. A boiler burns logs, pellets or chips, and is connected to a central heating and hot water

Biomass Cofiring - an overview | ScienceDirect Topi

A major problem of biomass cofiring comes from the evaporation of alkali and other compounds in the biomass that causes fouling and corrosion of boiler tubes. In gasification, one can strip its product gas of the alkali in the biomass prior to combustion, and thereby minimize the impact of the impurities in biomass on fouling and corrosion of

Options for Biomass Fuels Utilization in Power Plan

The preferred approach of co-firing biomass in a PC boiler is to feed the biomass into a dedicated mill so it can be dried at around 100 C (200 F) while the coal is dried at around 275 C (525 F).

Biomass Cofiring in Coal-Fired Boile

One of the most attractive and easily implemented biomass energy technologies is cofiring with coal in existing coal-fired boilers. In biomass cofiring, biomass can substitute for up to 20% of the coal used in the boiler. The biomass and coal are combusted simultaneously.

Wood-Chip Heating Systems A Guide For Institutional and Commercial Biomass Installations By Timothy M. Maker Originally prepared for The Coalition of Northeastern Governors Policy Research Center Washington, D.C. 1994 Revised by Biomass Energy Resource Center Montpelier, Vermont With funding from the U.S. Forest Service 2004

How to tell if boiler is over firing? — Heating Help: The Wa

If you are firing oil, and want to downfire, gross BTU output is determined by multiplying the gph of the nozzle X 140,000 BTU (or thereabouts, the heat content of heating oil is usually computed from 136K-140K, depending on region) and then multiplying by steady state efficiency which ought to …

Biomass Heating Plant - Biomass - Longwood Universi

Author: Chia-Chi Chang, Yen-Hau Chen, Wei-Ren Chang, Chao-Hsiung Wu, Yi-Hung Chen, Ching-Yuan Chang, Min-Hao Once the wood is processed, the wood fuel will be stored at the processing facility until it is transported to the new heating plant. Biomass Facts. Test firing of new boiler occurred in July 2010; Campus uses 10,000-35,000 lbs. of steam/hour; Each boiler produces a maximum of 20,000 lbs. of steam/hour; Purchase sawdust from several local sawmills
