With more and more companies investing in Vietnam, the country’s electricity consumption is very high. Recently, there is a shortage of electricity in Vietnam, so let’s see if there is a market for waste heat recovery boilers in Vietnam’s electricity consumption market.
News about electricity shortage in Vietnam
According to a report by Vietnam Electricity Group (EVN), Vietnam is facing the possibility of a power shortage of 4,900 megawatts in the northern region, due to hot weather, low rainfall, low water levels in hydropower reservoirs, and a significant increase in demand.
Vietnam’s power shortage is a “wake-up call” for the government, which needs to speed up the decision-making process for power market reforms.
Vietnam relies on coal and hydropower, and renewable energy is unlikely to solve the problem in the short term, despite a recent solar boom. Coal-fired plants accounted for about 60% of power output last week, while hydropower was affected by low rainfall.
What is waste heat boiler?
A waste heat boiler, also known as a heat recovery boiler, is a specialized type of boiler that is designed to recover and utilize waste heat generated from industrial processes or exhaust gases. It captures the heat that would otherwise be wasted and converts it into usable energy, such as steam or hot water. Waste heat boilers play a crucial role in improving energy efficiency and reducing environmental impact.
The primary source of waste heat can vary depending on the industry and application. It may originate from processes such as chemical reactions, combustion of fuels, or thermal operations like drying or smelting. The waste heat is typically carried by exhaust gases, flue gases, or high-temperature process streams.
The waste heat boiler utilizes the captured heat to generate steam or hot water, which can be used for various purposes within the same industrial process or for other applications. By recovering and reusing this otherwise wasted heat, waste heat boilers contribute to substantial energy savings, cost reduction, and lower greenhouse gas emissions.
