Экономайзер
Shell & Tube Heat Exchangers
Recovered heat is typically used to preheat feedwater or процесс water, reducing fuel consumption.
About the Экономайзер
Recovered heat is typically used to preheat feedwater or процесс water, reducing fuel consumption.
Tanpera экономайзерs are manufactured to проект requirements with coiled tube bundles and flanged connections.
Эффективность and Fuel Savings
As a practical rule of thumb, every 20 °C drop in flue-gas температура corresponds to roughly a 1% increase in бойлер эффективность.
Therefore экономайзер size and target outlet температура are determined by evaluating both energy gain and condensation / acid-gas corrosion risk together.
Condensation and Material Selection
When gas outlet температура falls below a certain level, acid gases that cause corrosion begin to condense. In standard (non-condensing) применения, flue-gas температура must not be reduced below this critical threshold.
In that case the экономайзер must be manufactured from stainless material; otherwise the corrosive effect of condensed water seriously shortens equipment life.

Часто задаваемые вопросы
It is a теплообменник that recovers part of the heat from hot flue gases leaving a бойлер or furnace before they go to the stack. Recovered heat typically preheats feed or процесс water, reducing fuel consumption; as the gas inlet–outlet температура difference grows, the эффективность gain increases.
It typically increases бойлер or plant эффективность by 3% to 15%. Practical rule: every 20 °C drop in flue-gas температура means roughly a 1% бойлер эффективность gain.
When gas outlet температура falls below a certain threshold, acid gases condense and cause corrosion. In standard применения this threshold must not be crossed. In natural-gas condensing системы, 50–60 °C is possible; in that case the экономайзер must be manufactured from stainless material.
In Tanpera Экономайзер применения, typical payback is between 3 and 24 months. Actual time depends on fuel price, operating hours, and the температура drop achieved.
Such эффективность применения may benefit from EVÇED VAP (Эффективность Improvement Проект) поддержкаs. Eligibility and поддержка amount are evaluated on a проект basis.
They are used for flue-gas heat recovery in heat, steam, and electricity generation plants; промышленные бойлер rooms; furnaces; and chemical and food plants.
Flue-gas расход and composition, inlet/outlet температураs, allowable перепад давления, target water flow/температура, fuel type, and condensation risk are required. Tanpera’s engineering team performs material and capacity selection together.
Gas-side загрязнение and outlet температура should be monitored regularly; in condensing системы, condensate drainage and stainless surface integrity must be checked. Periodic очистка and производительность measurement preserve эффективность.
