Sellers Boilers

Sellers Engineering Company was founded in Chicago in 1931 when new industries were looking for ways to take advantage of natural gas energy. Sellers pioneered gas-fired equipment such as boilers, burners, water heating equipment and bakery equipment.

In 2008, Sellers Engineering was acquired by Green Boiler Technologies (GBT) and in March 2014, TK Capital, LLC, an investment firm based in Oakbrook Terrace, Illinois, became the controlling shareholder.

Respecting the legacy of durability and longevity with Sellers equipment, we revised our name from GBT to Sellers effective September 1, 2014 and our legal name changed to Sellers Manufacturing Company in May, 2016.

Sellers Manufacturing Company is well known throughout the world as offering the highest quality equipment with unrivaled reliability, efficiency, ease of maintenance, durability and cost effectiveness.

COMPANY INFORMATION

SELLERS S-SERIES STEAM BOILER

The Sellers immersion fired S-Series steam boiler is a horizontal, single-pass, firetube boiler designed to burn natural gas. The unique burner assembly delivers pre-mixed air and gas through multiple nozzles. The air-gas mixture is ignited as it exits each flame retaining nozzle at high velocity The resulting flames are long and small in diameter. The flame from

each of these nozzles is directed into a 2″ O.D. tube that is completely immersed in liquid. There is a separate tube for each flame with the same amount of heat going into each tube. These small diameter flames burn in the first half of the tube lengths. Therefore, the “fire shines“ on half of the heating surface in the single pass boiler — 50% of the total heating surface is radiant heating surface.

The high percentage of the radiant heating surface, the low heat input into each tube, and the even distribution of heat throughout the multiple tubes virtually eliminate thermal stress problems that are common in multiple pass boilers.

SELLERS X-SERIES STEAM BOILER

The Sellers immersion fired X-Series steam boiler is a horizontal, single-pass, firetube boiler designed to burn natural gas. The unique burner assembly delivers pre-mixed air and gas through multiple nozzles.

SELLERS P-SERIES STEAM BOILER

The Sellers gas fired steam boiler is a horizontal single pass packages unit of a uniquely simple design. Instead of having a single large combustion chamber, the gas is burned inside many small tubes. These ” immersion fired” tubes are widely dispersed and totally submerged in the water. As a result, thermal stresses are greatly reduced. The boiler is completely water-backed and requires no refractory or brickwork.

Each of the firing tubes operates in an identical manner. The premix burner delivers the same amount of gas to each tube. This causes each tube to operate the the same temperature eliminating “hot or cold” passes. Combustion takes place and is completed in the forward half of each firing tube. Fifty percent of each tube provides primary heating surface upon which the fire shines. It is the quantity of primary heating surface in a boiler that determines the metal temperature in the zone of combustion, the hottest part of a boiler. Sellers large primary heating surface area keeps tube metal temperatures low. This reduces metal stresses and provides long equipment life.

SELLERS TWO PASS STEAM BOILER

The TPS Immersion Fired 6201 Series of Fire Tube Low and High Pressure steam boilers (20-125 HP) is well known throughout the industry for its unique small footprint compact two-pass design and dual fuel burner technology. Available in both high pressure (up to 300psi) and low pressure steam, the two pass immersion fire tube design delivers premixed air and gas through multiple burner nozzles. A corresponding “fire tube”, completely immersed in liquid, is aligned with the nozzle head inside the combustion chamber. Upon combustion, the nozzles generate a focused, high velocity flame which radiates down the center of each tube. The benefits of this technology in the TPB Immersion Fired Series fire tube steam boilers include: Natural Efficiency Up to 84% efficiency Two-pass design captures additional flue gas heat after heating primary surface Fuels: natural gas, LP gas, biogas O to 125 psi steam generated within 14 minutes Compact Design Saves Space Utilizes the same single-pass immersion technology Very compact footprint ( smaller sizes 24 sq. ft. up to 42 sq. ft.) Low Maintenance Cost and High Longevity Elimination of thermal shock due to balanced heat transfer across primary heating surface; allowing for up to 150° F ΔT Backed by a 20-year non-prorated thermal shock warranty- Indusrty’s Best warranty ! Ease of Maintenance Hinged door provides quick access to burners, manifold and heating tubes for easy cleaning and routine maintenance No refractory; thereby reducing annual maintenance and replacement costs Trimmed with non-proprietary components Full inspection of the boiler interior within 15 minutes ! Simplicity of Design No complex controls which require intensive training Fewer moving parts reduces incidence of failure and required retuning Low NOx Emissions Less than 30ppm NOx.

SELLERS YGNIS STEAM BOILER

The YGNIS Series of steam boilers is a unique three pass, dual fuel (natural gas & #2 oil) horizontal fire tube, water-backed steam boiler design developed and perfected in Switzerland and now is a standard in the EU community.

Available in both high-pressure and low-pressure steam, this particular shell design overcomes thermal shock problems common to other multi-pass boilers. Thermal stress is greatly reduced because of two unique features of the furnace.

Firstly, the larger diameter, shorter furnace produces less thermal expansion than a furnace of an ordinary boiler. Secondly, the furnace end is supported by stays which are attached to the rear tube sheet. Tube sheet fatigue failures are eliminated because shear stress between the furnace and the rear tube sheet is greatly reduced. Solid Efficiency Up to 83% efficiency Three-pass design captures additional flue gas heat after heating primary surface Dual fuels: natural gas, #2 oil, biogas, LP gas Simplicity of Design No complex controls which require intensive training fewer moving parts reduces the incidence of failure and required re-tuning. Compact Design Greatly reduced footprint, as compared to industry 3 and 4 pass fire tube boilers, given relatively large diameter and short furnace design Low NOx Emissions Less than 30ppm NOx standard and 20ppm NOx available.
