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.

BOILERS Bureau of Energy Efficiency 27 Syllabus Boilers: Types, Combustion in boilers, Performances evaluation, Analysis of losses, Feed water treatment, Blow down, Energy conservation opportunities. 2.1 Introduction A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam.
Hydrocarbons, alcohols and acids - boiling points - Boiling temperature (°C and °F) with varying carbon number up to C33 Isopropanol (2-Propanol) based Freeze Protected Water Solutions - Freezing and flash points of isopropanol (2-Propanol) based water solutions or brines
File Size: 881KB Toxicity: Reagent alcohol (90% ethanol, 5% methanol, 5% isopropanol) is considered an irritant/narcotic; mutagenic/-teratogenic data. Isopropanol manufactured by the strong acid process is listed in group 1 by IARC. Workers manufacturing isopropanol by this process showed increased sinus and laryngeal cancer.
High-temperature hot-water (HTHW) plants are typically designed to operate at temperatures ranging from 350°F to 420°F. The system pressure must be at least 25 psig above the saturation pressure of the high-temperature water’s maximum temperature to prevent …
SZS series gas-fired steam boiler. Capacity:10-100 t/h; Pressure:2.5-9.8 Mpa; SZS gas-fired steam boiler is "D" type chamber structure. Furnace is on right side and convection tube bundle is on the left. The proper is fixed on the basement by middle and both end flexible supports and make the boiler to expand horizontally to sideways.
Keywords: Refined Glycerin, Electrolysis, Purification, Biodiesel 1. Introduction Crude Glycerin is the by-product of biodiesel production via transesterification of triglyceride as shown in figure 1. In this process, triglycerides (1) are reacted with an alcohol such as methanol (2) with base catalyst to give alkyl
GLYCERIN. More precisely, however, glycerin applies to purified commercial products containing 95% or more of glycerol. GLYCEROL (CAS registry No. 56-81-5; NIOSH No. MA8050000) refers to the chemical compound 1,2.3-propanetriol, CH, OHCHOHCH,OH, and to the anhydrous content in a glycerine product or in a formulation.
May 14, 2008· The process block diagram on the previous page illustrates the different process steps for the purification of crude glycerin from biodiesel by the Ambersep BD50 process. Crude glycerin from storage is first heated to 194 degrees Fahrenheit on a plate heat exchanger, using energy recovered from the purified glycerin stream, plus live steam.
