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.

Cited by: 8 Oct 22, 2019· A summary of the inventory data used in the LCA of the biomass boiler is shown in Table 2. As shown, operational data, including the boiler efficiency, woodchip energy content, ash generation, and emissions of CO,

Life cycle assessment for the combustion of biomass wast

Author: José Adolfo Lozano Miralles, Rafael López García, José Manuel Palomar Carnicero, Francisco Javier Re Biomass from agriculture, crop residues, forestry, landscape management, and wastes from industry and households can be used for energy recovery. In a project commissioned by the Swiss Federal Office of Energy (SFOE), a life cycle assessment (LCA) of the direct combustion of different non-wood biomass substrates was performed.

Beginner's Guide to Biomass Boilers | Homebuildi

There is no more chance of a biomass boiler failing than there is of any other boiler. In fact, a biomass boiler will retain its efficiency (more than 90%) for maybe twice as long as a gas or oil boiler. One solution that many people like to consider, however, is to retain their existing oil or LPG set-up as a back-up.

Life cycle assessment of residual lignocellulosic bioma

May 14, 2018· Environmental impact assessment. The life cycle assessment (LCA) method, following ISO 14040-14044 standards [25, 26], was used to estimate the overall net environmental impact associated with producing bio-jet fuel from recovered residual woody biomass.The life cycle environmental impacts were assessed using the Tool for Reduction and Assessment of Chemicals …

Comparative study of heat pump system and biomass boil

LCA methods with two methodologies has been used in the present work to determine the impacts of two systems of production of heat, a heat pump system and a biomass boiler system. Despite different methodologies used, the result has confirmed that:

Biomass Boilers | Wood Pellet | Wood Chip | Log | Tre

Cited by: 30 What fuel do biomass boilers use? Whilst there is a wide range of material that can be classified as biomass fuel such as grain, miscanthus and chicken litter, the vast majority of systems use 1 of 3 main types of fuel; log, wood pellet and wood chip.Logs are a popular choice of fuel for those who have access to a lot of woodland and tend to achieve the greatest fuel savings.

The Net CO2 Emissions and Energy Balances of Biomass a

2.3. LCA of a Plant Cofiring Biomass with Coal An LCA was conducted on the production of electricity from a coal-fired power plant cofiring waste (primarily urban) biomass. The power plant is similar in design to the average case studied in the coal LCA, since currently operating coal-fired boilers can obtain the most benefit from cofiring biomass.

Heating systems LCA: comparison of biomass-based applianc

Jun 14, 2013· Biomass provides an attractive solution for residential heating systems based on renewable fuels, even though biomass-based domestic heating systems are recognized as significant particulate matter emitters; thus, a life cycle assessment (LCA) approach was used in the study to compare two different appliances: a wood stove and a pellet stove, both modeled according to the …

Life cycle assessment (LCA) of an integrated bioma

The shift section consists of a two stage process with a high temperature reactor (450 °C) and a low temperature reactor (250 °C). The whole amount of steam required for the two reactors (extracted from the steam turbine) is fed to the first reactor , .The exothermic reaction that consists in the conversion of carbon monoxide and steam into carbon dioxide and hydrogen is the following: CO

Life Cycle Assessment of Burning Different Solid Bioma

Cited by: 148 carriers from the different biomass substrates, they can be fermented for a conversion into biogas, they can be converted into biofuels or they can be burnt directly in order to receive heat or to generate electricity. In this project a life cycle assessment (LCA) of the direct combustion of different non-wood biomass substrates is performed.
