We will discuss important steps involved in Boiler gas tightness test procedure. -Close all the dampers in the grate hopper of the boiler. -Run the FD fan and open all the dampers excluding the dampers in the grate hopper. Keep air pressure and running time as approved by design. Detect leakage by soap solution /smoke …View More
Entrapped air will drastically increase the time taken to reach the test pressure. Running the hydrostatic test pump increases the boiler pressure gradually till the test pressure. Normally the test pressure is is 1.5 times the maximum allowable operating pressure. Close the pump discharge valves to lock the system pressure.View More
This procedure defines the requirement and procedure of hydrostatic testing of the boiler pressure parts after completing the assembly of all the boiler high pressure and temperature components. Hydrostatic testing Objective Hydrostatic testing in the boiler is carried out to check the following: Leakages in the boiler pressure parts (Tubes, headers and Pipes).View More
Oct 12, 2015 · For fire tube boiler out of service for short period. The boiler must be completely filled with alkaline water. The boiler must be topped up periodically and any air in the system must be got rid off. Regularly test the boiler water and keep the alkalinity in the range of recommended value. If the boiler is to be taken out of service for longView More
Oct 31, 2017 · You see, your pressure relief valve is designed to prevent your boiler from building up too much pressure and will automatically discharge hot water/steam when pressure levels hit a dangerous level of 30 psi (pounds per square inch) or higher. Another sign of high pressure levels is a boiler that also makes a loud humming noise when operating.View More
Nov 18, 2014 · There has been discussion on another thread regarding using compressed air to test a boiler. The attached pictures show why this is a bad idea. The tank in the picture is a pressure tank for a well at a golf course. The tank would have been 3/4 full of water and the rest air with between 50 and 100psi of pressure.View More

Multiple Choice Questions on Steam Boilers and Engines - Set 16 MCQ Steam Boilers Edit Practice Test: Question Set - 16. 1. The air pressure at the fuel bed is reduced below that of atmosphere by means of a fan placed at or near the bottom of the chimney to produce a draught. Such a draught is called (A) Practice Test: Question Set - 02 1.View More
An increase in temperature results in an increase in electrical conductivity. For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for every 1°C increase in temperature. This can be written as: Example 3.12.3. A boiler water sample has an unneutralised conductivity of 5 000 μS/cm at 25°C.View More
Boilers that are not provided in packaged form can be delivered to the job site in pieces for assembly in the boiler room by people with the various skills required. industrial watertube boilers can be field erected (see Figure 1-5) but, in most cases, smaller boilers of both watertube and firetube concept are available for field assembly.View More
Boiler problem 1: no hot water. A lot of Worcester boiler faults are noticeable initially through having trouble heating your home. Worcester boiler problems with heating are often evident through the temperature of the water coming through your taps or within your radiators.View More
All boilers have a gauge that indicates the pressure inside. The gauge is generally found on the side of the boiler. This device will tell the homeowner if the pressure in the boiler is excessive. Step 2 – Reading the Boiler Pressure Gauge. The pressure gauge on smaller home boilers should maintain a level of twelve to fifteen pounds.View More
