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:
spherial dished head - Bing 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.
A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. Pressure vessels can be dangerous, and fatal accidents have occurred in the history of their development and operation.
25/3/2009· Dome calculations are painful to do by hand. It’s not impossible, just time consuming. So I have written this simple calculation worksheet to help. It will calculate the most commonly needed measurements for a dome — both spherical or oblate.
Pressure Vessel Design and Calculators . For the thin-walled assumption to be valid the vessel must have a wall thickness of no more than about one-tenth (often cited as one twentieth) of its radius. The classic equation for hoop stress created by an internal pressure on a thin wall cylindrical pressure vessel is: σ θ = PD m /2t for the Hoop

This study on knuckle-encroaching nozzles of diameter ratio d i /D a =0.2 in a Klöpperböden torispherical head of diameter/thickness ratio D a /S e =118 has shown that: 1. The nozzle has very little influence on the limit pressure of the head, even when it is located in the knuckle region of the head. 2.
14/7/2012· This article is related to Boilers and Welding course in Mechanical Engineering. The article was submitted to Dr. Arun Thakur at Allahabad University. Its main points are: Mandatory, Design, Based, Stress, Analysis, Fatigue, Evaluation, Design, Acceptability, Derivation
DIN6319 Spherical Washers, Stainless Steel, Male or Female. These spherical washers are used for clamping on non-parallel surfaces or between parts with uneven or irregular faces. The two parts of the washer come together to provide a flat surface. When utilising hexagon nuts with spherical seating DIN 6330 the male washer is redundant.
· PDF fileEffects of Local Reinforcement on Nozzles in Dished Ends D H Nash and J Hitchen Abstract The results of a parametric design study, to determine the optimum diameter of reinforcing pad for nozzles in the knuckle region of an ellipsoidal pressure vessel head are presented herein. The study utilised a linear elastic finite element model, created
Pressure Vessel Heads. Ellipsoidal Head, Hemispherical Head and Torispherical Head are three types of ASME Pressure Vessel Dished Heads. Ellipsoidal head This is also called a 2:1 elliptical head. The shape of this head is more economical, because the height of the head is just a quarter of the diameter.

There are 3,203 pipe end seal suppliers, mainly located in Asia. The top supplying countries or regions are China, Vietnam, and Taiwan, China, which supply 99%, 1%, and 1% of pipe end seal respectively. Pipe end seal products are most popular in North America, Domestic Market, and South America.
A spherical cap is the region of a sphere which lies above (or below) a given plane. If the plane passes through the center of the sphere, the cap is a called a hemisphere, and if the cap is cut by a second plane, the spherical frustum is called a spherical segment. However, Harris and Stocker (1998) use the term "spherical segment" as a
Female spherical washers, also known as dished washers, are the bottom washer in a spherical washer assembly. Male Spherical Washer (15) Male spherical washers, also known as seat washers, are the top washer in a spherical washer assembly. Bolt Size:
