Boiler and specify different holes for which answer water tube boilers corrosion, the following is mainly to answer some specific questions, which mainly are: the boiler furnace in the manholes and hand holes, which specifically refers to what? In addition, for low and high temperature boiler corrosion, how should it be understood? These are the problems associated with the boiler, therefore, let's learn it. 1. boiler furnace in the manholes and hand holes in the boiler, manholes, which refers to access for people in the sewer, etc. in order to carry out maintenance work. And thus it can enter and leave Pai Road, boilers and water pipes and other such facilities. The hand hole, which can be considered to reduce the manhole. Mounting object thereof is to facilitate the installation, removal, cleaning and maintenance work, namely, to facilitate the work of some of the internal device boiler. These two, is basically the same in structure, and is a short tube section of blind plates. In diameter, hand hole is 150-200mm, and there DN150, DN250 both nominal diameter. The manhole is in the 1000mn above. 2. The low temperature low and high temperature corrosion of boiler corrosion boiler: heating surface in the rear of the boiler, such as an air preheater and economizer, etc., if present, and sulfuric acid, then combine with water vapor to form sulfuric acid vapor, together with the temperature is not high, the sulfuric acid vapor will condense on the heating surface, thus forming the sulfuric acid corrosion, that is, low temperature corrosion. And, it is mainly found in the air preheater, but again there will be the economizer. High-temperature corrosion of the boiler: the boiler at a high temperature state, an alkali metal sublimation, and the flue gas is reacted with sulfur trioxide to produce a composite sulfate, then, have a heating surface tubes and boiler wall, causing corrosion. So, these one corrosion, known as high-temperature corrosion. Also, pay attention to that which is generally repeated, if not promptly treated, then the wall will gradually thinning, the worst case, there will be burst pipes phenomenon.
WATER TUBE BOILER 2 Water flows through tubes that are surrounded by hot combustion gases in a shell. Usually rated in tons of steam/hr Used for H.P. steam High capacity.

67. Water tube boilers are those in which (a) flue gases pass through tubes and water around it (b) water passes through the tubes and flue gases around it (c) work is done during adiabatic expansion (d) change in enthalpy (e) none of the above. Ans: c. 68. Locomotive type boiler is (a) horizontal multitubular water tube boilerOnline chat
Watertube boilers, on the other hand, only require roughly 10% of the water in firetube boilers. This helps to limit the risk of too much water turning into steam instantly and blowing the doors off the boiler, which is possible with conventional boilers. More importantly, all of the water is confined inside the tubes. If one of those tubesOnline chat
D type watertube boiler design. D type watertube boilers are designed with a large steam drum at the top, vertically connected to a smaller water drum (or "mud drum") at the bottom, via multiple steam-generating tubes which carry feed water (providing the main heat transfer surfaces for the production of steam).Online chat
Modern boilers are made of alloy steel to withstand high pressures and extremely high temperatures. Most conventional steam boilers are classed as either fire-tube or watertube types. In the fire-tube type, the water surrounds the steel tubes through which hot gases from the furnace flow.Online chat
