This boiler will have a safety valve set to "pop off" at 35 PSI. Joe safely rated it a bit higher but being even more conservative then a true engineer I will be running it a bit lower. Joe designed sort of a "dryer" coiling inside the smoke box to dry the steam..not so much a super heater but a dryer which will definitely help the condensation
This is a vertical, fire tube boiler commonly used for small capacity steam generation. It is an improved type of simple vertical boiler in order to minimize heating surface.
When boiler cold enough , Clean water and firesides. All of the boiler mountings to be overhauled and displayed for survey. Gags or clamps must be prepared for safety valves. Boiler must be filled with water at a temperature not more than 38 ° C for fire tube boiler and not more than 82 ° C for water tube boiler. Drip pan placed under all
49. In a water tube boiler the fire passes through the tubes. (False) 50. What are the two basic types of boilers? Ans: Fire Tube: - In fire tube hot flue gases are kept inside the tube and water kept outside the tube .fire tube boiler are small in capacity And in water tube boiler water inside the tube and hot flue gases are outside the tube.
The Westinghouse Universal Fire Tube Boiler is a true industry standard of excellence. Features. 316L stainless steel, fire tube heat exchanger 10 to 1 turndown ratio Advanced modulating gas condensing boiler; up to 95% AFUE Equipped with highly innovative gas leak detector Venting: 2" or 3" PVC, CPVC or Polypropylene
Gas fired boiler safety valve chattering The dithering phenomenon occurring in the emission process of safety valve is called safety valve chattering,it can easily cause metal fatigue,decrease the mechanical properties of the relief valve,causing serious hidden trouble of equipment,so we need to take measures to deal with that.
Fire Valves are designed as a fire safety shut-off valve for use on oil burning equipment.The valve is installed in the oil supply pipeline outside the building with the sensor mounted firmly inside the appliance above the burner.

1. Water tube. 2. Fire tube. In water tube boilers, water circulates through the tubes and hot products of combustion flow over these tubes. In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by water. Fire tube boilers have low initial cost, and are more compacts. But
(C) The safety valve capacity of each unfired steam boiler must allow the safety valve or valves to discharge all the steam that can be generated by the boiler without allowing the pressure to rise more than 6.0% above the highest pressure to which any valve is set, and to no more than 6.0% above the MAWP.

19. In a water tube boiler the fire passes through the tubes. Answer: False 20. What are the two basic types of boilers? Answer: Fire tube and water tube 21. A gauge glass allows you to see how much water is in the boiler. Answer: True 22. What is the purpose of a safety relief valve on the boiler?
A safety valve is set to allow escape of steam at pressures above normal operating pressure; this device is necessary on all boilers, because continued addition of heat to water in a closed vessel without means of steam escape results in a rise in pressure and, ultimately, in explosion of the boiler. Fire-tube boilers have the advantage of
Boiler safety valves are activated by upstream pressure. If the pressure exceeds a defined threshold, the valve activates and automatically releases pressure. Typically used for gas or vapor service, boiler safety valves pop fully open once a pressure threshold is reached and remain open until the boiler pressure reaches a pre-defined, safe

12. Regulator valve: It is a valve that regulates the steam through the main steam pipe for superheating. 13. Safety valve: It is used to maintain the safe working steam pressure in the locomotive boiler. It blows off steam when the pressure of the steam increases above safety level and prevents blasting of the boiler.
