Product thermal capacity : 1-20 t/h Working pressure : 0.7-2 Mpa Available fuel : Nature gas, coke oven gas, biogas, methanol, liquid propane gas, diesel, heavy oil, light oil, crude oil, etc. Available industries : Heat supplying, chemical, food, textile, printing and dyeing, cigarettes and tobacco, fodder, pharmacy, building materials, brewery, rubber, hospital etc. Introduction:
steam boiler which has deaerator 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 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.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
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.
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.
2019-5-26 · 4 Things to Know for Increasing Steam Boiler Deaerator Effectiveness Author: Joshua Ince - Business Development Manager Knowledge Direct Want to share this DO2 studies are important because they can identify when something has failed mechanically inside the deaerator, limiting its ability to remove oxygen or other non-condensable gases.
While oxygen and carbon dioxide could be removed by the addition of scavenging chemicals to the feedwater alone, this practice is extremely costly in all but the smallest plants. Generally speaking, plants generating in excess of 10,000 lb/hr of steam can justify the installation of a Deaerator.
A remote deaerator is similar in design to an integral deaerator, except it is not connected to a low-pressure evaporator system of the HRSG. Without a heating steam source of its own, a remote deaerator will rely on pegging steam from the HRSG or another source to
AN OVERVIEW OF BOILER DEAERATION OPERATIONThis feature also raises the feedwater temperature, thus requiring less boiler fuel to convert the feedwater to usable steam. Boiler tubes, condensate lines, and process piping have a much longer useful life by eliminating the pitting action of untreated water. This advantage alone justifies the cost of an “OXYMISER” deaerator. How Does It
2019-5-9 · A deaerator is a device that removes oxygen and other dissolved gases from water, such as feedwater for steam-generating boilers. Dissolved oxygen in feedwater will cause serious corrosion damage in a boiler by attaching to the walls of metal piping and other equipment and forming oxides (rust). Dissolved carbon dioxide combines with water to
Steam Pressure Control. Deaerator uses Low pressure steam from the process plant at a pressure range between 0.5 to 1.5 bar. The low pressure steam sources may be any one of the following: Extraction from back pressure turbines, Flash steam recovered from Boiler blow down or Letdown steam from High pressure steam header through pressure
2010-1-1 · Every boiler plant has a deaerator that generally gets little or no attention until it jeopardizing the entire steam system. These incidents can be expensive to correct and affect the integrity of other critical auxiliary equipment as well as the careers of those charged with technical oversight of utility systems. Deaerators are large, insulated tank-car-shaped pressure vessels.
2019-5-24 · The deaerators are normally used in any chemical process industry or in power plants where the boiler is used for the production of steam from the boiler feed water. The heating deaeration process is the separation process done by using mechanical equipment that has been designed in such a way that is used for the work process as desired.
2019-5-26 · Although many feel it is part of normal maintenance, the repair and replacement of condensate lines, boiler tubes, etc. can be made unnecessary with a deaerator. Few engineers consider the installation of a steam boiler without seriously considering that of a deaerator
