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.
To compliment our nationwide boiler service team, Cochran has established a Chemical Descale Service. Our main objective is to provide the best solution to keep your boiler free from scale and corrosion, also to maximise the efficiency and prolong the life expectancy of your valuable asset - Your Boiler.
Boiler Cleaning | Chemical Cleaning and Descaling The build up of hard water scale in boilers, heat exchangers, cooling towers and pipework reduces the efficiency of heating equipment. Acid washing is the only satisfactory method of removing scale deposits. Heat exchangers that use river or sea water for cooling can also build up deposits due…
User rating: 5/5 ENVIRONMENTALLY SAFE TO DISPOSE OF IN DOMESTIC FOUL DRAINS SUCCESSFUL IN DESCALING BOTH MODEL, MINIATURE AND FULL SIZE ENGINE BOILERS. Dynamic Descaler is a revolutionary liquid descaler that rapidly dissolves all water scale and lime along with mud, rust and other non-soluble sedimentation deposits safely and effectively.
so descaling steamers is a regular part of what I do if the boiler's been neglected. I go for a good inhibited hydrochloric acid product. I've had good results with the Nu-Calgon acid descaler. The "inhibited" part of the name indicates that it will not attack the boiler metal for a given period of time, usually about 8 hours.
May 27, 2014· Had the same problem and valiant engineer deemed there was dirt in the system when boiler was installed 6 months ago, price quoted for boiler …
Boiler Treat Ultra+ is non-corrosive, non-fuming, odorless, non-irritating to the skin, and biodegrades 100% in less than 10 days, making it the safer choice for boiler cleaning. This formula comes in a liquid concentrate that dissolves 10% more scale than muriatic/hydrochloric acid, has a pH of zero, and carries a triple-zero HMIS score.
CFB (circulating fluidized bed) coal-fired steam boiler YLW series coal-fired/biomass-fired thermal fluid heater YQ(Y)L series gas-fired/oil-fired thermal fluid heater
Oct 11, 2016· The boiler feed water pump must be isolated by a valve. Also, the pressure control system and sight glass valves should be isolated. The bottom blowdown valve on the boiler can be used to connect to the discharge of the recirculating pump. This is …
Immediately add the Scalzo followed by a small amount of Chardon’s CTA-800 (4 oz per 1000 gallons). Check pH before starting boiler knowing it has not mixed in well just yet. pH should be between 1-3. Promptly have the boiler operator operate the boiler to heat the cleaning solution in the boiler to a maximum of 130 F. DO NOT BOIL THE WATER
User rating: 4.6/5 Jun 26, 2017· Soda ash (Na 2 CO 3) may be used to increase the boiler water alkalinity. It partially decomposes at boiler temperatures and pressures to produce caustic soda (NaOH) and carbon dioxide (CO 2 ) gas. Since the carbon dioxide adds to the neutralizing amine demand in the condensate, the use of caustic soda as the alkalinity builder is preferred.
I hate to make posts that seem to be chemistry lectures, but perhaps this summary of the chemistry of scale might be helpful. This is an attempt to put the chemistry of scale into a single post. Scale formation is a serious problem with many (maybe most) water sources. The "scale" is usually either CaSO₄, CaCO₃, or MgCO₃. Most scale is calcium carbonate, CaCO₃.
