Energy-saving boilers are also called waste heat boilers. As the name implies, they refer to boilers that use the waste heat in various industrial processes, waste gas or waste liquid and the heat generated by the combustion of combustible substances to heat water to a certain working fluid. Compound Gas Nitriding Treatment Process For Swing Arm BogiesOil-fired boilers, gas-fired boilers, and coal-fired boilers with waste heat recovery and utilization of smoke boxes and flues are also called waste heat boilers. Waste heat boilers can produce hot water or steam for use in other sections through waste heat recovery.Vertical double-barreled shotgun receiver vacuum heat treatment principle Fuel, gas, and coal are burned to generate high-temperature flue gas to release heat. The high-temperature flue gas first enters the furnace, then enters the waste heat recovery device of the front smoke box, then enters the pyrotechnic pipe, and finally enters the waste heat recovery device in the flue of the rear smoke box. The flue gas becomes low-temperature flue gas and is discharged into the atmosphere through the chimney. Because the waste heat boiler greatly improves the utilization rate of the heat released by fuel combustion, this kind of boiler is very energy-saving. Due to the complex manufacturing process of waste heat boilers, the production cost is relatively high, so the boilers are expensive.Aluminum alloy chassis vacuum brazing process composition Oil-fired gas-fired energy-saving boilers are mainly composed of burners, controllers, power distribution boxes, furnaces, pyrotechnic pipes, front and rear smoke boxes (internal replacement hot water jackets), flues and chimneys; coal-fired energy-saving boilers are mainly composed of furnaces, water and fire pipes, overheating It consists of evaporator, evaporator, economizer, front and rear smoke boxes, flue and chimney.Vacuum Brazing Technology of Aluminum Alloy Plate Radiator

The ultra-high temperature pyrolysis gasification melting reactor is a fixed bed vertical reactor under normal pressure. Working according to the principle of moving bed, the inside of the gasification melting furnace is divided into drying, oxidative decomposition and reduction melting stages in layers from top to bottom.5A06 Sheet metal parts vacuum annealing The solid waste is charged from the upper part of the furnace and descends while exchanging heat with the gas rising from the lower part of the furnace. The synthetic gas discharge device discharged from the upper part of the gasification melting furnace. The solid waste in the thermal decomposition section descends together with coke and limestone into the reduction and melting section, and the controllable melting reduction reaction is carried out with the help of oxygen-rich supplied from the air inlet. Under ultra-high temperature conditions, all inorganic components are completely melted and discharged in liquid form at the bottom of the reactor.Vacuum Detection Technology of Vacuum Annealing Furnace Conventional solid waste incinerators mainly include mechanical grate incinerators, rotary kiln incinerators and fluidized bed or circulating fluidized bed incinerators. The fly ash of these furnaces contains a large amount of heavy metals (Pb, Cd, Hg, etc.) and dioxins.Vacuum brazing of the rear passage assembly of the flame tube

Ceramic heat exchangers Ceramic heat exchangers have the following characteristics: a. High temperature resistance, corrosion resistance, good heat exchange effect and high energy saving rate. But the part where the metal heat exchanger is placed on the ceramic heat exchanger is quickly burned out.Vacuum heat treatment of aerospace materials b. The use method of the ceramic heat exchanger is direct, simple, fast, less one-time investment, low investment cost, stable heat exchange temperature, high efficiency, long life, no blockage, no air leakage, easy to replace, and there is no gas when switching waste away.Vacuum annealing process of automobile half shaft c. In terms of service life, the ceramic heat exchanger is several times or dozens of times that of the metal heat exchanger under the same conditions.Advantages of vacuum sintering of cemented carbide If the heat exchanger is not used, the temperature of the combustion-supporting air is normal temperature (-10℃-40℃), but the temperature of the combustion-supporting air heated by the ceramic heat exchanger can reach 300℃-800℃, which can not only achieve the purpose of energy saving, but also improve the environmental benefits.Linear Optical Axis Vacuum Quenching The waste heat recovery and utilization of the heating furnace can achieve an energy saving rate of 1% to 2%.

Energy saving measures of heating furnace Heating furnaces, various industrial furnaces, and boilers are all high-energy-consuming kilns that consume a lot of resources. When the heating furnace heats the ingot, the temperature is high, and the flue gas takes away a large amount of high-temperature heat, resulting in wasted waste and low heat utilization rate. Measures to save energy and reduce consumption include:Heat Treatment of DZ4 Alloy in High Pressure Gas Quenching Vacuum Furnace 1. Paint RLHY-2 black body radiation energy-saving paint on the inner wall of the heating furnace, increase the radiation rate of the refractory material of the heating furnace wall, and speed up the radiation heat transfer in the furnace. This product can achieve an energy saving rate of 10%~20%.Vacuum Brazing Technology of Static Guide Vane Ring 2. The high emissivity barrel-shaped device is installed on the inner wall of the heating furnace, which also plays the role of improving the emissivity of the refractory material of the furnace wall, accelerating the radiation heat transfer in the furnace, and the energy saving rate of the product is 3%~6%. The disadvantage of this method is that The investment is too large and the cost recovery period is relatively long.C/C composite brake material

Oil-fired gas boilers refer to boilers that can use both oil and gas. A boiler that can only use oil is called an oil-fired boiler, and a boiler that can only use gas is called a gas-fired boiler.Vacuum Brazing Technology of Static Guide Vane Ring If the boiler is equipped with an oil-fired gas dual-fuel burner, then the boiler is an oil-fired gas boiler. Oil-fired gas boiler is a relatively general concept. Oil-fired gas boilers are mainly divided into boiling water boilers, hot water boilers, steam boilers and heat transfer oil boilers. When purchasing, choose different oil-fired gas boilers according to their own purposes.Heat Treatment of DZ4 Alloy in High Pressure Gas Quenching Vacuum Furnace Oil-fired gas boilers are different from coal-fired boilers in that they require a burner to inject fuel into the boiler hearth, and use a fire chamber to burn without using a grate facility. Since no fuel ash is produced after the combustion of the oil-fired gas boiler, the oil-fired gas boiler does not need a slag discharge facility. If the oil and gas injected into the furnace are mixed with air within a certain range or extinguished, it is easy to explode. Therefore, oil-fired gas boilers need to use automated combustion and control systems. The oil-fired gas boiler has a compact structure. The small boiler body and its ventilation, water supply, control and auxiliary equipment are all set on a distribution box. The large and medium-sized boilers can also be assembled and shipped.Surgical instruments stainless steel vacuum heat treatment
