Many years of experience in industrial/commercial boiler technology
High operational reliability
Ease of regulatory inspections
Low maintenance and service costs
The strictest quality controls applied throughout the entire production process
Low power consumption with high-efficiency electric motors

Design:

To ensure the safe manufacture and operation of our condensate tanks, we apply PD 5500, ASME VIII (Div. 1 & 2; ASME U, U2, R and NB), EN 13445, EN 14015 (BS 2654), API 650, API 6A, ASME B31.3, DNV Offshore Rules, NORSOK, GOST + SNIP, NACE MR0175/ISO 15156, PED 2014/68/EU. All electrical components are UL-listed and wired in accordance with the National Electrical Code (NEC).

Ease of Operation & Maintenance:

User-friendly controls and easy component access simplify operation and maintenance, minimizing downtime and cost. One-button start, self-monitoring with safe shutdown on faults, and a control panel that provides usage-based maintenance alerts make operation of the condensate tank safe and intuitive.

Safety:

Safety and standards compliance are our top priority. Our pressurized condensate tanks feature overpressure protection, level/flow monitoring, and emergency safe shutdown capabilities.

Materials:

Shells and dished heads are manufactured, depending on operating conditions, from S235JR or P355GH boiler plate, or from AISI 304/316 stainless steel for hygienic applications. Nozzle pipes are made to EN 10216-2 from P235GH/P265GH seamless boiler tubes or from AISI 304/316 stainless tubing.

Material Selection—Key Considerations:

Corrosivity of the working fluid
Installation requirements (ATEX, explosion-proof)
Maximum allowable process pressure and temperature

Efficiency:

50 mm high-density insulation delivers low heat loss. Thermal insulation is jacketed with galvanized and painted cold-rolled steel sheet featuring a low λ (thermal conductivity). All insulation materials meet low conductivity and high density criteria.

Environmentally Friendly Design:

With energy-efficient pumps and equipment, the goal is lower power consumption and reduced operating cost.

Customization:

Every plant is different. Based on process analysis, we tailor our field-proven equipment to your needs and provide the engineering and site support required for design, manufacture, and successful commissioning of condensate tanks. You acquire not only a condensate tank, but also TSB Energy’s expertise.

Available add-ons for each condensate tank:

Heat recovery systems
Piping systems
Very high efficiency
Simple, easy maintenance
Robust design for long service life

What Is a Condensate Tank? When Is It Used?

In plants where steam is used as the heating medium, steam that has transferred most of its energy to the process is removed via steam traps and returns as condensate to the boiler feedwater tank (condensate tank). The boiler feedwater tank is the pre-feed water reservoir for the boiler. Units are produced in horizontal and vertical types. A properly designed condensate tank greatly reduces the loss of condensate energy to the atmosphere.

Selecting the Ideal Condensate Tank:

Because flash steam can be released to atmosphere from the high temperature in the condensate tank, a flash steam tank is recommended.
The ideal boiler feedwater temperature is 70–80 °C. As needed, to prevent thermal shock in the boiler, heat the feedwater to this range using a heating coil or live steam.

TSB Energy recommends using an economizer: Installing an economizer at the boiler stack outlet both prevents thermal shock in the feedwater and recovers flue gas heat.

Note: Every 20 °C of excess stack temperature corresponds to roughly 1% of fuel cost. The average payback period of TSB Energy economizers is 4–5 months.

Design calculations for condensate tanks must match the intended operating pressure; based on these, plate grade and plate thickness are determined. On request, a thermal deaerator can be supplied to protect the piping and boiler from corrosive gases.
