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.
May 30, 2018· 1. Refineries use Water tube boiler more than Fire tube boilers. 2. Reboilers (Kettle type boilers) are heat exchangers typically used to provide heat to the bottom of industrial distillation columns. They boil the liquid from the bottom of a dist
CO boiler. In the hydrocarbon processing industry, the operation of a fluid catalytic cracking unit (FCCU), depending on its arrangement, produces gases rich in carbon monoxide (CO).To reclaim the energy in these gases, the FCCU can be designed to include a CO boiler to generate steam. For refineries generating large quantities of CO, field-erected boilers such as the PFI boiler are used.
CARBON MONOXIDE (CO) BOILER THERMAL OXIDIZER There are no carbon copies. As a worldwide leader in thermal oxidizer solutions, Zeeco is the company to trust for your CO Boiler application. Our engineers have decades of experience in designing these systems for petroleum refineries around the globe. We are a supplier of
Steam for refinery use can be generated from one or more of these following sources: fired steam or unfired steam generators, turbine exhaust or extraction. Figure 10-7 shows the general design principles for establishing refinery steam systems.The steam system consists of steam generators and a distribution network at different pressure levels for process and utility requirements.

Working together, the two companies offer streamlined
Refineries utilize a continuous supply of high process steam to maintain refining operations, and steam is vital to sustain operations. Nationwide Boiler offers a range of boiler rentals and boilers for sale, including our 75,000 lb/hr, 750 psi / 750 F superheat watertube boilers, designed specifically for high pressure applications, aimed at
Author: ChemicalEngineering The above are the major water and steam circuit items in a boiler and are collectively called the ‘pressure parts’. This post is part of the series: Working Of A Power Plant Boiler. Boiler in a power plant has two functions. The Combustion system converts energy in coal to Heat. Water and steam system converts the heat to steam at high
Cracking and related refinery processes Steam cracking. Steam cracking plants (Figures 1 and 2) use a variety of feedstocks, for example. ethane, propane and butane from natural gas. naphtha, a mixture of C5 to C10 hydrocarbons, from the distillation of crude oil. …
The coil type boiler generates steam instantly and is extremely easy to install and commission. These boilers are designed for safe and reliable operations. Coil type steam boilers are designed to operate on a wide range of liquid and gaseous fuels including diesel fuel, heavy oil, light oil, gas, etc.
