FCT COMBUSTION NEWSLETTER: MARCH 2020
These are testing and unprecedented times that have been thrust upon us, and our hearts go out to all the people affected by this invasion of the Covid-19 Corona virus.
As time goes on, it is becoming more apparent that the direct and indirect consequences have changed all of our lives probably forever. The health and safety aspects are enormous as every jurisdiction is attempting to limit the scope and rate of infections to give health systems the best chance to cope, and clearly many countries are struggling with this.
At FCT, we have adopted all recommendations applicable to safeguard the health and welfare of our staff, customers, business associates and stakeholders, and we will continue to do that.
We are in an extremely busy stage of projects currently across many countries in the world, and these projects will be delivered on time in every aspect that relies upon FCT Combustion. However, this depends somewhat on the ability of sub-suppliers and freight to continue operation – which is the case so far – and FCT is actively monitoring them for any potential change to find options for on-time delivery if needed.
It helps that we have full operating bases in a number of countries where our main customers are based, and have choices of sub-suppliers in many countries also that allows us to tailor our project delivery to meet the circumstances and need. It also helps that within FCT we are familiar and organised to work remotely so that we have many staff working effectively from home now due to the isolation measures recommended to minimise the spread of the corona virus.
The future of the world economies and related business activities post this pandemic is unknown to anyone at this time. At FCT we will endeavour to ride through this storm and put ourselves in the best position to meet our customer needs post this event – whatever that looks like.
For now, we will continue with normal business activities as best we can and complete existing orders and strive to gain new ones.
We are indeed grateful to our loyal customers both new and old that have supported and trusted us to deliver our products and services for the past 35 years and allowed FCT to continue the growth particularly in recent years.
We sincerely hope and pray that all of you stay safe and healthy during these times, and that your families and your business is minimally affected by these terrible events.
We can only hope that the world finds a cure for this virus and we all return quickly to some sort of normality in the short term.
I wish everyone the very Best.

FCT Combustion partners with ICON Empresas to offer a comprehensive range of hot gas generators
We are pleased to announce that in response to customer demand, FCT Combustion has entered an agreement with ICON Empresas to expand the breadth of our existing hot gas generator range with two new products.
The advantage of the FCT-ICON Solid Fuel Hot Gas Generator is that it eliminates the need for a grinding system to first pulverise fuel, increasing efficiency and reducing costs by allowing the use of cheaper solid fuels without the high capital expenditure that would normally go with this. The FCT-ICON Hot Gas Generator can operate with various crushed fuels including petcoke, wood chips and coal – thus reducing the cost of hot gas – and can be applied across a wide range of industries.
The second product is the FCT-ICON Mobile Grate Hot Gas Generator, which is able to use refuse derived fuel (RDF) and a range of other alternative fuels to produce hot gases for drying or mineral processing applications.
Complementary to FCT Combustion’s existing range of burner systems and accessories, the hot gas generators can be bundled to create a complete solution depending on the client’s needs. A recent example of this was a successful installation as part of FCT Combustion’s complete clay drying system solution for UCEM’s Chimborazo plant in Ecuador, where the Solid Fuel Hot Gas Generator was installed using lump coal and/or petcoke to generate hot gases for clay drying instead of having to mill the solid fuels.
FCT Combustion is proud of our relationship with ICON Empresas and the ability to offer this well proven equipment to our customers. With these two new products, in addition to our existing hot gas generator offerings, FCT Combustion now offers customers a complete range of conventional and special purpose hot gas generators to suit their needs.
The FCT-ICON hot gas generators have a strong reference list which, combined with FCT Combustion’s pyro-processing and project management expertise, will provide customers with innovative solutions they can depend upon.
Cauldron performs in extreme weather for the SEA Games
Congratulations to our sister subsidiary, FCT Flames, for the delivery of a spectacular cauldron for the Southeast Asian (SEA) Games. The cauldron was lit by champion boxer and current Senator Manny Pacquiao at the event held in the Philippines in November 2019.
With extensive experience supplying ceremonial cauldrons for high profile events including the Olympic Games, FCT Flames used exclusive technologies to ensure the cauldron was designed to perform under extreme weather conditions including heavy wind and rain in the lead up to Typhoon Kammuri.
FCT Flames worked with event organisers to create a cauldron that would complement the surrounding architecture and environment. The podium on which the cauldron sits, as well as the backdrop, was designed by National Artist for Architecture, the late Francisco “Bobby” Manosa.
Measuring 12.5m high, the podium incorporates various elements to symbolise the Philippines, including three main pillars to represent Luzon, Visayas and Mindanao, as well as 11 steps to represent each of the countries participating.
Masterclass: Fluidized Bed Hot Gas Generator concept and applications
The FCT-ICON Solid Fuel Hot Gas Generator (HGG) is able to use solid fuels without the need for grinding to first pulverize them. Below, we explain how the fluidized bed component works, enabling this innovative technology to provide economic savings and increased efficiency to our customers.
Fluidization is the physical phenomenon that causes a solid to have a fluid behavior. Is fundamentally based on the circulation of solids together with a fluid (gas or liquid) preventing the existence of temperature gradients, very active points or stagnant regions in the bed. It also provides greater surface contact between solid and fluid, favoring the transfer of mass and heat. In the case of the fluidized bed, this phenomenon facilitates the interaction of air with fuel evenly, without contact with metal or moving parts, and then combustion and generation of hot gases that will be used in subsequent processes, such as drying.
Fluidization occurs when an upward flow of fluid (gas or liquid) through a particle bed acquires sufficient velocity to support the particles, but without dragging them along with the fluid. The efficiency in the use of a fluidized bed depends first on the knowledge of the minimum fluidization velocity needed. Below this velocity the bed does not fluidize; and above it, the solids are dragged out of the bed.
GENERAL CHARACTERISTICS OF FLUIDIZATION:
- At very low speed : The fluid runs through small, tortuous channels, losing energy and pressure; and PD (Pressure Drop) is a function of permeability, particle roughness, density, viscosity and surface velocity.
- With increase of speed: It reaches a value that the dynamic action of the fluid allows reordering of the particles, in order to offer less resistance to the passage.
- Higher velocities: The particles cease to be in contact and looks like boiling liquid.
ADVANTAGES OF FLUIDIZATION:
- Surface area is larger, because the particles can be much smaller favoring the transfer of heat and mass;
- High reaction rates, compared to fixed bed reactors, due to bed uniformity (absence of gradients);
- Increase in heat and mass transfer coefficients due to increased conductance and temperature uniformity;
- Coefficients of heat transfer between bed and equipment walls or immersed pipes are extremely favorable;
- Easy flow in ducts, because the solids behave like fluid;
- Favoring energy transport due to fluidity.
Suitable fuel types
Due to the characteristics of fluidized bed HGG, a wide range of solid fuels can be used in heat generation. They can be used alone or mixed in more than two types. The proportions of this mixture may vary, but the points below must be respected.
Usually the main physical/chemical characteristics to be respected are:
- Grain size (depends on the fuel);
- Moisture (for handling and disposal purposes);
- Lower calorific value – LCV (normally above 2.500 kcal/kg);
- Melting contaminants in the ashes of fuel (Contaminants with melting point below 800 °C such as sodium, potassium, iron should be avoided).
The Solid Fuel HGG has the following main process characteristics:
- The HGG can work at temperatures from 500 °C to 900 °C without forced dilution system (depends on negative system pressure).
- The HGG can work at temperatures from 200 °C to 900 °C with forced dilution system.
- The HGG must work with negative pressure (at least -1 mBar).
- The HGG can generate thermal powers from 0,1 Gcal/h to 50 Gcal/h (or more, depending on the case and layout).
- The HGG has a modulation range from 60% to 100% of thermal power (may be more if more than one HGG is installed).
- The HGG can work with collection cyclone if particulate emission restriction exists (typical particulates are fine ash).
The Solid Fuel HGG can be applied in processes that needs hot gases such as:
- Drum dryers
- Rapid dryer
- Spray dryers
- Hammer mills
- Cement and raw ball mills
- Cement and raw vertical mills
