Generally, flue gases from the boiler exhaust are at high temperature and if this heat is not utilized will lead to a large number of losses resulting in reduced boiler efficiencies. So generally this waste heat is recovered by heating either air required for combustion or preheat water before sending it into a boiler.
2013/7/31 · The heat energy from the red hot coke is recovered in the waste heat boiler for use as steam, resulting in energy conservation as well as a reduction in coke particle emissions. Tab 2 shows the comparison of typical properties of coke produced by the two processes.
Straight tube, shell-and-tube waste heat boilers frequently develop tube and tube sheet failures due to the imposition of unequal stresses. A primary cause of this is the uneven distribution of hot gases across the face of the tube sheet. The tubes involved tend to come loose, creating leakage problems.
2021/10/25 · The boiler operates at existing distribution voltages, 4.16 to 25 KV with up to 99.9-percent efficiency, and can produce up to 170,000 pounds of steam per hour. With pressure ratings from 105 psig to 500 psig, the boilers are designed to ASME Section 1, and are certified, registered pressure vessels at the location of the boiler.
Economizers, or in British English economisers, are mechanical devices intended to reduce energy consumption, or to perform another useful function like preheating a fluid.The term economizer is used for other purposes as well. Boiler, powerplant, and heating, ventilating, and air-conditioning (HVAC) uses are discussed in this article.
Overview. India's immediate neighbour, Bangladesh has benefited from the innovative solutions created by Thermax since June 1978. Since then, Thermax has provided several industrial solutions like oil and gas-fired boilers, waste heat recovery boilers, vapour absorption chillers, as well as water and wastewater solutions.
Extraction of heat from hot coke is based on heat exchange through the direct contact of circulating inert gases with hot coke and transferring this heat to the waste heat boiler. Dry cooling method allows to recover about 80% of the heat taken by coke from the oven, or …
Heat Exchangers are available in many types of construction, each with its advantages and limitations. The main heat exchanger types are: Shell & Tube – The most common heat exchanger design type consists of a parallel arrangement of tubes in a shell [Figure 1].
