Waste heat boiler power generation

It’s described in too vague terms and covers a too wide range; the original poster had better first search our forum by themselves. It might be much more effective than making such general requests.

What are the components of the waste heat, and what are its temperature and pressure? How much waste heat can be generated per hour? Only with these conditions can the design of a waste heat boiler be considered. Generally, it is the user’s organization that sets the requirements, with the manufacturing company responsible for carrying out the design ； In some cases, the design is completed by a design institute, and then a company is hired to carry out the manufacturing ； In some cases, the design institute completes the preliminary design, and then the manufacturing company handles the preparation of the final drawings; it depends on how the design institute with which you are working wishes to proceed.

Actually, I don’t know exactly how much thermal energy can be utilized. It’s just that my boss saw in another project that the entire workshop was filled with heat, and he thought it was a waste, so he came up with this idea and asked me to take care of it. I have no idea where to start; I’m trained in electrical engineering, but I have no clue about converting heat into generator output power or anything like that. Can anyone help me?

It is best to involve a professional design firm in your project based on your operational conditions.

It’s usually the waste heat from the flue gas, right? It’s necessary to provide information such as the temperature and composition of the original flue gas, as well as the volume of flue gas. Parameters related to the process requirements, such as the desired exit temperature and pressure drop of the flue gas, must also be provided. Based on this information, the amount of heat released by the flue gas can be calculated. Then, using the desired thermal efficiency of the boiler and the parameters of the steam, the amount of heat absorbed and the output capacity of the boiler can be determined, which in turn helps in selecting the appropriate equipment such as turbines and generators. :lol

What industry is it? It is necessary to know the amount of flue gas and the composition of the waste heat-containing flue gas in order to design a waste heat boiler

What project is it? What is a waste heat carrier? Parameter! ?

The properties of the waste heat should be provided; if it is flue gas waste heat, then the volume and temperature of the flue gas, along with details such as the site and factory conditions, should be supplied. A boiler manufacturer of Class A can be engaged to design and manufacture this waste heat boiler.

1. First, figure out how much waste heat there is. 2. Determine the parameters of the residual heat. 3. Determine the power generation method based on parameters and residual heat. There are those that generate power through waste heat flash evaporation. (It is best to make use of the thermal energy from the waste heat directly, rather than converting it into electricity, or to use the waste heat for cooling.) 4. Determine the power generation amount. 5. According to the second law of thermodynamics, the parameters related to waste heat are very low, resulting in a very low power generation efficiency; moreover, the investment required per unit of electricity generated is high. The biggest constraint on the utilization of waste heat in this case is the excessively low cost-benefit ratio. Therefore, a technical-economic analysis is necessary; otherwise, the costs will outweigh the benefits. This post was last edited by Qin Yu on 2009-2-22 23:18]

You should hire professional designers and firms to design this for you, as a boiler is not a minor device – it’s a unit for generating steam. If the design is unreasonable, the risk of accidents during operation will increase significantly. So if you plan to install one, it’s best to have professionals handle the design for you!

Your boss does indeed have an awareness of energy conservation; it is recommended to hire professionals to conduct a comprehensive analysis of the workshop, identify the sections where waste heat can be effectively utilized, and determine the relevant parameters before proceeding with further design work!

This question is too general; if it’s really necessary, you can contact me by phone at 1345759426

First, you need to calculate the gas capacity in your area, and select factors such as flow rate, heat load, and site conditions
