Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressureLearn More

BOILERS Bureau of Energy Efficiency 27 Syllabus Boilers: Types, Combustion in boilers, Performances evaluation, Analysis of losses, Feed water treatment, Blow down, Energy conservation opportunities. 2.1 Introduction A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam.Learn More
Design Features and Benefits of our Water-tube Package Boilers. Gas-tight setting membrane – inhibits dew-point sulfur corrosion and outages caused by gas leaks. Larger tube diameter (2.5 in. [6.35 cm] tubes spaced 1 in. [2.54 cm] apart) – contributes to a faster load response and helps prevent membrane thermal cracking.Learn More
May 04, 2017 · Water tube boiler working and function. 1. Water Tube Boilers In this type of boiler water passes through the tubes while the gases remain in the shell side, passing over the tube surfaces • Used for high steam demand and pressure requirements • Capacity range of 4,000 – 120,000 kg/hour. 2. Water tube boilers.Learn More
3.Two types of high pressure water tube boilers are specified, flex tube and D-type. The two boiler types are significantly different, and only one of the two types should typically be specified if all new boilers in a given project are similar. 4.Flex tube boilers: a)Primarily for non-critical service firing gas fuel and with stable steam demands.Learn More
Aug 28, 2019 · Water Tube Boiler is a high-pressure boiler that operates at a pressure of about 165 bar. Basically, in this boiler, water will be flown inside the tubes surrounded by flue gases. More steam is generated by using this boiler so, the overall efficiency of the boiler is high. The water Tube boiler is shown in the figure below.Learn More

Water-tube boilers are used in power station applications that require: A high steam output (up to 500 kg/s). High pressure steam (up to 160 bar). Superheated steam (up to 550°C). However, water-tube boilers are also manufactured in sizes to compete with shell boilers.Learn More
by the tube supplier or the boiler manufacturer. The ERW tube specifications adopted by the ASME Code require, as a minimum, a flange test, a flattening test, and a reverse flattening test, which provide some control of steel quality and welding procedures. However, these required tests are …Learn More

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be …Learn More

pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.Learn More
Dec 18, 2018 · Kefid · This Project Standard and Specification covers requirements governing the design, fabrication, and inspection of gas and oil fired water tube boilers having steam outlet conditions not exceeding 750 psig and 800oF. REFERENCES Throughout this Standard the following dated and undated standards/codes are referred to. Get a QuoteLearn More
Water-tube boilers feed water (rather than combustion gases) through tubes. A large number of these tubes run through a boiler drum (casing) where heated gases or heating elements surrounding the tube bring the water to its boiling point. This heat transfer method makes water-tube boilers more thermally efficient than fire-tube boilers.Learn More
