Waste heat recovery waste heat boiler

oneProject Background

according totuneCheck, the total waste heat resources of various industries account for approximately% of their total fuel consumption17% -67%, can The waste heat resources recovered and utilized are approximately equal to the total waste heat resources60%.

Your company has a large amount of flue gas emissions and high temperatures, There is utilized space, Successful utilization can benefit the companysection provinceA large amount of expenses.

expensivepublicThe company has a practical need to use steam, and by utilizing the waste heat from flue gas to generate steam, it can achieve reasonable heat consumption Energy conservation, consumption reduction, and pollution reductionThe purpose of pollutant emissions.

2、 Preliminary scheme preparationaccording to

Your ExcellencyDepartmentexisting1 unitOne waste circuit board disposal combustion furnaceThe specific parameters and requirements are:combustion furnaceWhat is the hourly displacement of the crew 1200m3，Considering the energy-saving effect and investment cost, it is recommended to recover the waste heat of flue gas as a whole.

1The total smoke volume of the equipment is: 1150m3/h(Working condition)

flue gasImporttemperature 1150 ℃, smokeboileroutlet temperature 450℃

flue gasboileroutlet temperature 450℃，Condenser outlet temperature155℃

Purpose: To produce saturated steam

Saturated steamingSteam temperature160~ 180℃

3、 Basic aspects of project proposal preparationprinciple

(1) The design scheme strives for practicality, reliability, safety, and operability, and the equipment selection is economical and durable、 reliable and stable.

(2）Fully utilize existing equipment space, optimize design schemes, and reduce infrastructure investment;

(3）Strictly implement the corresponding current national standards and relevant enterprise technical regulations.

4.2 Waste heat recovery flue gas flowCheng

rootAccording to the on-site conditions of your company's flue gas waste heat reuse, we will 1150 ℃ waste heat flue gas, introducing waste heat potThe furnace fully absorbs heat and the flue gas cools down to 45After reaching around 0 ℃, connect the smoke that has released heat to the outlet condenserFully absorb heat from flue gas0.3 secondscool down to 155After about ℃originalMain flueEnter the bag filter againContinue with the next emission process.

4.3 Steam grid connection point

rootaccording toThe customer needs to merge the steam main network nearby for use in the later stages of the process. Entering the office every hour Net steam refers to the total loss of steam, Corresponding amount of water needs to be replenished every hour.

6、 Waste heat boilerStructure and performance characteristics

thatsurplusThe hot boiler is a horizontal water tube boiler. Due to the low temperature of the waste heat flue gas, the boiler does not emit radiation receiveHot surface, The heating surfaces are all convective tube bundles. The waste heat flue gas flows directly from the inlet into the convective heating surface, even ifTowards the flushing convection tube bundle, Heat exchange with water in the drum to generate steam.

waterfollowThe loop method is natural circulation, with the upper drum and lower convection tube bundle connected by an ascending pipe Form a loop.

flue gasAdequate circulation area, Therefore, it does not affect the chimney suction and smoke ventilation.

thissurplusThe hot boiler is a fully assembled boiler, and high-quality insulation materials are used to reduce heat loss Warm effectfruitGood waste heat is fully utilized, with significant economic benefits. The waste heat boiler is fully assembled on site, oneSecondary transportation, on-site positioning, connection to the flue, installation of water replenishment and main steam pipelines are ready for use.

Features:

1. The furnace has a simple and reasonable structure, with almost no maintenance workload, and can achieve single-layer fabricplace 便To observe, control, and operate.

2. OperationFor convenience, Low labor intensity.

3. Without mechanical operating components, the failure rate is extremely low.

4. The installation workload is small, and the installation and operation costs are relatively low.
