Control Systems

Is your boiler operating inefficiently?  Contact Blake Thermal and start saving money. On average, our customers see a 4% – 6% fuel savings and in some cases up to 20% or more!

Replacing the single-jackshaft system with parallel positioning is an effective solution with dedicated motorized actuators for the fuel and air valves, electrically tying them into the electronic firing-rate control on the boiler. 

Variable-speed drive (VSD) enables a motor to operate only at the speed needed at a given moment rather than a constant speed (rpm) regardless of load demand. This reduces energy consumption with better control of excess air.

Increase efficiency and reduce fuel costs with integrated boiler room controls. SCADA systems, building automation system communications and fuel monitoring all help your equipment operate at maximum efficiency. Cleaver-Brooks offers a full line of integrated boiler controls, communication systems, packaged water controls, water level controls and stand-alone controls. Increase efficiency, reduce fuel costs and decrease emissions with control systems designed to get the most out of your boiler room with a retrofit control package.

Burner Upgrades

Today’s burners are designed for high-efficiency, high turndown and low emissions. Increasing the burner turndown rate will increase energy savings because on-off cycles are reduced. Often, high-turndown burners can work in conjunction with a multiple-boiler lead-lag control system, delivering even more energy savings due to an even further reduction in cycling.  Whether commercial, industrial, firetube or watertube we can estimate an ROI for your consideration. 

Fuel Conversions

Whether you need assistance converting from gas to oil or oil to gas, we have a simple solution for you. There are many reasons to fire a backup fuel in case of an emergency. Our specialists can assist in selecting the proper conversion kit for your application. 

Let us help you determine if a fuel conversion can save you energy dollars, increase efficiency, and reduce emissions for the equipment in your facility. Contact us for a free estimate today.

Heat Recovery

The right type of equipment for a boiler system depends on several factors such as boiler type, fuel used, stack materials and operating conditions.

A standard economizer transfers energy from the boiler exhaust gas to the boiler feedwater in the form of sensible heat. An economizer captures and redirects sensible heat from the hot flue gas that goes up the boiler stack and would normally be lost BTUs. This sensible heat increases the temperature of boiler feedwater. On average, adding a standard economizer increases boiler system efficiency on average by 4 – 6%. 

A condensing economizer captures both sensible and latent energy from the flue gases leaving the boiler. Two types of condensing economizers are available. There is a standard one-stage condensing economizer and a two-stage condensing economizer. In the two-stage system, the first stage is non-condensing and the second stage is condensing, so the system can heat two sources of water. Adding a condensing economizer with the proper heat sink can increase energy efficiency by as much as 20 percent.

A blowdown heat-recovery unit is the most energy-efficient method of purging destructive solids from any steam boiler system. The unit transfers heat energy typically lost during continuous blowdown, transferring it to the cold makeup water. The payback in fuel savings is typically less than a year.

A flash economizer uses the surface blowdown to heat up the makeup water. It recovers blowdown energy in the form of flash steam (latent heat) and blowdown (sensible heat). By capturing both sensible and latent heat, a flash economizer can recover more heat than the blowdown heat-recovery unit. Payback for a flash economizer often is less than a year.
