Technical advice on boiler combustion control

2020-7-22 · Ensuring that the heat-transfer surfaces of the boiler are clean is a major point of focus for managing the thermal energy in exhaust gases. Energy can be recovered from exhaust gases by transferring thermal energy from the high-temperature gases to boiler feedwater, or to the combustion air entering the boiler.

Boiler Efficiency and Combustion | Spirax Sarco

Heat losses in the flue gases. This is probably the biggest single source of heat loss, and the Engineering Manager can reduce much of the loss. The losses are attributable to the temperature of the gases leaving the furnace. Clearly, the hotter the gases in the stack, the less efficient the boiler. The gases may be too hot for one of two reasons:

Exhaust gas economizer on auxiliary engines

2016-5-12 · The exhaust gases hold a temperature between 270 ℃ and 320 ℃ for slow two stroke engines, and 350 ℃ to 480 ℃ for medium speed four stroke engines.Modern engines have the auxiliary boiler will run continuously to uphold the steam pressure required. The auxiliary

Exhaust Gas Boilers And Economisers for Marine

2020-7-13 · It is simply a row of tube banks circulated by feedwater over which the exhaust gases flow. Individual banks may be arranged to provide feed heating, steam generation and superheating. A boiler drum is required for steam generation and separation to take place and use is usually made of the drum of an auxiliary boiler.

PROCEDURE FOR DETERMINING THE THEORETICAL

2019-5-22 · gases which are emitted by the boiler is a function of the firing rate and associated theoretical air requirements and excess air used in the combustion process. The more excess air used, the larger the volume of exhaust gases for a given firing rate and the lower the exit gas temperature. The volume rate of flow of the exhaust gas can

Exhaust Gases from Combustion and Industrial

Exhaust from the combustion of this fuel represents the major volume flow emission point. Control equipment is not normally used. Equation IV-1.1 can be used to calculate the flow rate from this source, assuming 25% excess air, 1050 BTU/scf of natural gas and .0750 Ib/scf air. Exhaust flow rate (scfm) Natural gas use (1000 scfh) x 222.
