Our services cover the provision of ERK water tube boilers, fire tube boilers, firing systems, heat exchangers and engineering services in industrial and power plants. On request, we can provide moredetailed references and even organise site visits to all

Fouling is the most common cause of efficiency problems. This article discusses causes and solutions to these problems. When boiler water turns to steam solids are left behind. Bottom blowdown and surface blowdown are two methods to reduce solids and

This ash is sticky and poses many problems to boiler operators, especially in units that have been converted to handle this type of coal from another type of coal. The ash fusion temperature is lower compared to other coals, and the slag is incredibly sti

html Boiler fouling is obstructing the flow of energy from the fire/flue gas to the steam in the Figure: The fouling is visible on the waterwall. The process of slagging is closely related to that of fouling.

The mathematical model of a steam boiler has been developed, showing the influence of water-wall slagging and superheater fouling on the boiler performance. With traditional methods, operators often are not able to detect the critical build-up of deposits

11/25/2004 · In the present research, high-temperature corrosion in a high-capacity steam boiler using heavy fuel oil has been studied. The benefits of the use of some additives to avoid corrosion in this area as well as the behavior of some operational p

fouling level of each heat transfer surface of the boiler is needed. Monitoring techniques become more and more important for the study of boiler behaviors and ash fouling influence in coal-fired power plant boilers and have attracted extensive research e

Boiler fireside fouling and corrosion problems are mainly restricted to coal and oil fired installations. There are very few reported incidents of corrosion associated with gas fired units, the problem here being mainly confined to overheating due to inco

of fouling deposits with chemicals and/or mechanical antifouling devices or the replacement of corroded or plugged equipment. Typically, cleaning costs are in the range of $40,000 to $50,000 per heat exchanger per cleaning. Fouling in heat exchangers is n

As a facility manager, you will be working alongside your water treatment specialist as they offer guidance and support. But, in order for your boiler and cooling systems to run at maximum efficiency long-term, it will be crucial for operators to know how
