Numerical Simulation of Smoke Flow During Highway Tunnel Fi

In order to effectively investigate the fire safety system for highway tunnels,this paper proposes a mathematical model and a physical model to describe the smoke flow in the tunnel,with the Tianfu Highroad Tunnel in Chengdu as the research object.On the basis of

how to set up fire tube boil

Highlights A dynamic model has been developed for the analysis of boiler performance. The mathematical model is based on the first principles. The model gives the dynamic performance during nominal operation and the start-up. The model proposed is useful to assist plant engineers and for training operators. fire-tube boilerfīr tüb bȯil

Failure Mode Effect Analysis (FMEA) on Heat Recover

2015-11-30 · fire tube boilers or water tube boilers. The differences between the two are several, such as the position of the water and hot gases. In a fire tube boiler, hot gases are inside the tube and water is at outside the tube, while water tube boiler has water inside the tube and gases on the outside.

Heat transfer in fire-tube boilers - Željko Varga

A research of heat transfer in two-pass fire-tube boilers with a reversing furnace was conducted. A mathematical model for the heat transfer in the fire-tube boilers was developed and a corresponding computer software model then written. The model enables a more accurate analytical assessment of the impact of coiled-wire turbulence promoters on the heat transfer and pressure drop in boiler tubes.

Dynamic analysis of the boiler drum of a coal-fire

2019-8-25 · The developed model has then been validated with actual plant data obtained from a 210 MW coal-fired thermal power plant. The performance of the open loop responses of the model are analyzed and are included in the results and discussion of the paper. The model provides support for level, pressure, and temperature measurements and predictions.

Numerical investigation of heat transfer in 4-pass fir

through greater use of mathematical modeling and computer simulation 6,7. The purpose of this work is the elaboration of a calculation program in order to estimate the heat transfer between the combustion gases and the boiler internal surfaces in 4-pass fire-tube boiler under different operating conditions.

A Simplified Model for the Control of 600 MW Supercritica

Aiming at a 600MW supercritical unit,a simplified model of linear lumped parameter is built,which is fit for small disturbance simulation in rated condition.The transfer

Modelling and Simulating for Marine Exhaust Ga

Abstract. Based on the established dynamic mathematical model, the MATLAB/Simulink is used to analyze the dynamic characteristics of the boiler, and the model of the four zones, namely, the first convection zone, the second convection zone, the metal zone and the steam zone, are used to establish the mathematical model.

Gas Fired Hot Water Boiler Prices - hotelanand.co.

In this paper, a mathematical model of an oxy-fuel combustion boiler system with flue gas recirculation is investigated. The reduction of CO 2 emission from coal-fired power plants is an important research issue in alleviating the global warming. The entire dynamics are decomposed in two main parts; fire-side dynamics and water-side dynamics.
