Effective Boiler-Level Control | HPAC Engineering

A high rate of flow of feedwater into a drum can cause burner firing rate to vary as the pump switches on and off. For instance calculations show that with high-temperature feedwater burner firing rate may have to be 40-percent higher with a feed pump on. This continuous variation causes: Wear on burner controls. Temperature cycling.

(PDF) boiler efficiency and firing rate | lourdu joe ...

boiler efficiency and firing rate. Lourdu Joe. the changing requirements for steam or hot water at a given time in the process means boilers have to move through their firing ranges to meet demand most of the time operating at 60% or less of their full firing range (capacity).This leaves two important factors to consider: boiler turndown and boiler efficiency throughout the firing range.

Firing rate control system for a fuel burner - Honeywell Inc.

FIG. 1 is a plot of the firing rate 10 of a burner for a boiler plotted against the pressure 11 within the boiler. When the burner is activated at 12 the burner operates at high fire 14. As pressure builds up in the boiler at 15 you reach a pressure point P1 that is the beginning of a modulating range.

Boiler control - Plant Services

Feb 25 2004 · In parallel the boilers share the total demand using equal firing rates. On load increase the firing rate of each increases equally until the load requires an additional boiler. Then the firing rate of the active boilers decreases to compensate for the firing rate of the additional boiler. Steam boilers generally use parallel modulation.

Boiler Fuel - an overview | ScienceDirect Topics

Fluidized combustion (Ch.5) especially in its pressurized form should permit coal firing rates for watertube boilers (Ch.10.3) up to 58 MW/m 3 to be obtained. Atomized fuel oil and air are more readily mixed by their mode of introduction and ash substances in the products of combustion though by no means negligible are present in much smaller amounts than with coal.

How to Destroy a Boiler -- Part 1

The standard warm-up curve for a typical boiler does not increase the boiler water temperature over 100°F per hour. It is not unusual for a continuous minimum fire to exceed this maximum warm-up rate. Consequently the burner must be intermittently fired to ensure that this rate is not exceeded.
