Cold Starting or Warming Up or Initial Starting Of Boiler Cold starting means starting off the boiler from a state of comparatively lower temperature and pressure than normal working values. In other way we can say that cold starting is starting the boiler for the first time in its lifespan.
So the start up is done with the boiler plant at less than full load capacity and the feed water pumps pressure is not equally balanced between boilers. This procedure should be part of a standard or code to make sure the boiler plants are tested at full load conditions.
the boiler room are properly trained on all equipment, controls, safety devices and up-to-date operating procedures. 3) Before startup, ensure that the boiler room is free of all potentially dangerous items like flammable materials that could cause a fire. Clear intakes and exhaust vents. Check for deterioration and possible leaks.

Startup and Shutdown of Boilers Contact IHRDC Sales for Corporate Purchases Add to Cart Price: US$55.00 Description: This is an interactive training module designed to familiarize trainees with basic techniques for starting up and shutting down drum-type boilers.
Before starting the boiler. The following things should be checked thoroughly before starting the boiler: All the up-takes for the exhaust gases should be checked properly for a clear flow and to prevent any kind of obstacle or diversion.All the dampers should be checked for open position. All the vents should also be kept open.
To start the combustion, auxiliary burners and ignitors are required . This article describes the three most common burner arrangements - tangential and tilt tangential, down-firing, and wall firing - and the difference between primary and secondary air in the boiler. Also discussed is the start-up method for coal-fired burners.
As designers go for lower and lower exit gas temperature the size of air pre-heaters go up. Boiler tuning for optimal Dry gas. Keep an optimal excess air level, generally about 20% in a coal fired boiler; Tune combustion of coal to the optimal condition. Understand the coal being fired
Mar 18, 2016 · HOT START UP Below mentioned sequence to be followed to bring back the boiler into service during hot startup. Normalize the drum level. Drain the bed through the bypass gate up to no unburnt coal is observed in the bed. Start the ID Fan, PA Fan and SA fan as per start-up sequence described in boiler cold start up procedure Bring back all the
For a complete list of requirements, refer to the NESHAP final rule for industrial, commercial, and institutional boilers. Sending in the Initial Notification Form. For new boilers, your Initial Notification Form is due to EPA or the delegated state agency within 120 days after startup. Find the mailing address for your completed forms.
The start-up rate of the boiler is limited by the following items: 1. Allowable heat up rate of refractory, to achieve acceptable refractory life. 2. Elimination of temperature stress that could cause leaking tube joints. 3. If sulfur or HCl is present in normal fuel effluent, start the heating process on clean fuel until the dewpoint is passed.
• Track boiler pressure and temperature, especially at the steady state to determine if it’s keeping up with the load. • Take a stack temperature reading to determine how efficiently the boiler is operating. A well-tuned boiler should have a stack temperature ranging between 50 – 100 degrees above the steam or water temperature.
As you prepare to start up boilers for the colder months ahead, keep the following maintenance tips in mind to help you avoid the most common boiler heating problems. Have a competent service firm disassemble the low water cut–off and make–up water feeding devices.
Observe the start-up sequence. It may be necessary to isolate the boiler from the system to warm it up slowly. Verify the flame conditions in the combustion chamber. On gas fired non- condensing boilers a cold start may produce condensate leaking from the gas pass covers and casing. Once the boiler water temperature exceeds 150 ° F the
during all types of start up, and shut down and cool-ing. With this information the operators are able to minimize damage, maximize the asset’s life and reliability while reducing maintenance costs.
