Molten salt heaters use molten potassium nitrate and sodium nitrite as heating media. Molten salt heater will heat the powder salt over the melting point until the viscosity of the molten salt allows circulating pump works, after the whole system is under circulating condition, then feed then into the thermal fluid heater for further circulating rising temperature to make it to be recycling used. Normal media working temperature is 400-550℃, top working temperature could reach 600℃.

Waste Heat Boilers - Sulphuric Ac

The waste acid decomposed in a regeneration furnace contains solid residues broadly known as ash. This ash remains molten at the high operating temperatures of the furnace. When the gas enters the boiler, the molten ash will deposit on the relatively cooler outside surface of the tubes.

Flue Gas Boiler - Waste Heat Boiler - Zhong Ding Boiler C

Otherwise, the flue gas boiler could be used in oil/gas fired combined cycle units, and take advantage of the high temperature flue gas heat discharged by gas turbine. Generally, the flue gas boiler is installed in gas duct, generate steam by absorbing the flue gas waste heat, and decrease the exhaust smoke temperature.

waste heat boiler sulphuric acid plant | Industrial Coa

This series boiler is horizontal fire tube 3 pass oil gas fired steam boiler. Steam capacity is 1-25 ton per hour, thermal efficiency is 92%.

How Is The Low Temperature Corrosion of Boiler Caus

For example, the pressure of water vapor in the flue gas of an oil fired boiler is about 0.008~0.014Mpa, and the corresponding thermodynamic dew point is 41~52℃. When the concentration of sulfuric acid vapor in the smoke is 10%, the dew point is increased to 190℃.

Waste Heat Recovery Boiler for Sulfuric Acid | Reliabl

Owing to different procedures of different acid making approaches, the waste heat boilers developed by this company and applied in recycling of sulfuric acid waste heat and power generation project include sulfuric acid-making waste heat boiler and pyrite acid-making waste heat boiler. The structures of boiler include fire-tube type and water-tube type.

SULFUR TRIOXIDE FORMATION IN THE PRESENCE OF RESIDUAL OI

SULFUR TRIOXIDE FORMATION IN THE PRESENCE OF convective section of a residual oil-fired boiler. The model includes a global description of the rates of forward and reverse reactions at the deposit surface sulfuric acid (Halstead, 1978; Penfold and Smith, 1982).

12 Ways To Avoid Boiler Tube Corrosion - BOILERSMI

strong muriatic or sulfuric acid -- is rated as 1; a strong alkaline solution -- concentrated caustic a new boiler, or in one which has been drained and refilled with cold water, as the water warms Circumstances may have been such that the boiler was immediately fired when the old set of

Fluidized Bed Combustion Boiler in Sulfuric Aci

Fluidized bed combustion boiler produces steam in sulfuric acid production process. Sulfuric acid is one of the most important compounds made by the chemical industry. It is widely used in metal processing for example in the manufacture of copper and the manufacture of zinc and in cleaning the surface of steel sheet.

Sulfuric Acid Plant with Cogeneration of Power | SpringerLi

Whether the steam is generated by waste heat recovery system alone or whether any additional system is also involved (e.g., coal fired boiler running in parallel). (b) Whether the exhaust steam from the turbine can be used for process heating elsewhere in the premises, or exported to nearby units.

Sulfuric acid dew point corrosion in waste heat boile

This paper presents the sulfuric acid dew point corrosion found on waste heat boiler tube for a copper smelting furnace. Macroscopic and microscopic observation results for the failed boiler tubes are shown.
