Translate this pageTypically, the materials used for the heating surface are mild steel at the hot end and low-alloy corrosion-resistant steel (corten) or enamel for the cold end. In particular if the heating surface is exposed to severe corrosive operating conditions, the special enamel coatings developed by AGT will extend the heating surface lifetime considerably.
Air Preheated Regenerative Baskets are a compact arrangement of profiled metal sheets placed in the air preheated rotor in two or more layers and plays the most important role in the process of heat recovery. The bottom layer, or the cold end layer, is where the air enters and the flue gases are discharged, and is therefore, subjected to severe corrosion due to acid dew point. Air Preheater Spares - Products - AIR SYSTEMS Ltd.Types of Air Preheaters There are two types of air preheaters for use in steam generators in thermal power stations:One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater. These may be arranged so the gas flows horizontally or vertically across the axis of rotation. 1. Tubular Type Air Preheater

weathering steel rotor frame using UNS SS0316 (AISI 316) bolts. The gas from the outlet is approx. 85ºC and is led via the booster fan to the stack. The flue gas ducts after the GGH were carbon steel, and were in some cases protected with a Zn rich epoxy primer.

Corten Steel, Carbon Steel. Lead Time. 30 Days. Trademark Howden enamelled SurePack ElementsAir preheater elements, particularly those in gas-gas heaters for flue gas desulphurisation applications and on boilers firing high sulphur fuels, oil or coal, are subject to extreme attack from fouling and corrosion. Under such conditions, the absence of protection, or enamelling of a poor quality, can lead to serious corrosion or failure.

Your Air Heater's Operational Performance Corten or equivalent steel is the standard material used for the cold end replacement elements. This material provides increased corrosion resistance for the elements that are subjected to continual exposure to acid condensation on the cold end layer. 409 Stainless Steel Heating Surface is available Patco TechThe other major factors affecting design and operation of Air Pre-heaters are:Corrosion:The use of cold elements of higher-grade steel or enamel coating will reduce the effect of corrosion. Hot and fouling :With tough ash particles in the hot end elements, the profiles are such selected so as to reduce fouling and facilitate easier cleaning.
From the above two reasons, it is clear that initial cost as well as the operating cost can be kept minimum with regenerative air preheaters for higher size boilers.? Less weight of metal permit economic usage of alloy steel like corten steel elements in the low temperature section thus corrosion problem is combated to a great extent. Power Plant Boiler Heat Pipe Air Preheater Cost China Power Plant Boiler Heat Pipe Air Preheater is a heat exchanger that uses the flue gas heat from the rear of the boiler to heat the air needed for combustion.The tube and tube plate can be sealed with heat resistant packing, and can be sealed by welding.Following two types of air preheaters for use in steam generators in thermal power stations is commonly used:One is a tubular type built into the boiler flue
Q345NQR Corten Alloy Steel Sheet Plate For Economizer Air Preheater. Corten Steel resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions. The surface of the metal can form a coating of dark brown oxidation, which inhibits deeper penetration, so it saves the cost of need for painting and costly rust-prevention for Power StationsPreheater GmbH is able to supply air preheaters with vertical or horizontal shafts. In order to cover all possible applications and offer the boiler designer maximum flexibility, AGT developed three designs of integrated regenerative mill APH based on the traditional bi-sector type:Tri-Sector Air Preheaters Quart-Sector Air Preheaters Concentric Air Preheaters.
The Company offers its services for all types of Air Preheaters in the market across the world. The elements are generally manufactured in Corten Steel for Cold End Baskets and in Carbon Steel for Hot/Hot Intermediate End Baskets. The thickness of the Elements ranges from 0.45mm to 1.6mm and depth up to 1500mm.
