Thermal oil heater is a direct current boiler based on the design idea of forced circulation. The thermal oil boiler adopts the three-return coil design, and the system has set up the expanded water tank, which realizes the low-pressure high-temperature heating. It adopts coil structure, sufficient heating surface, expansion fully absorbed. Imported low NOX combustion machine, full combustion, belongs to environmental protection products.
The thermal oil boiler can be fully controlled by advanced touch screen computer controller and digital computer controller. With automatic temperature regulation, automatic ignition, and differential pressure, overtemperature, flameout protection. Boiler manufacturing specifications, in strict accordance with the relevant national standards. The whole fast installation factory, beautiful appearance, bright color.
Coal-fired thermal oil heater uses coal as fuel and thermal oil as heat carrier. Generally, there are three types of coal burning structure: vertical hand burning, horizontal cylinder burning, and horizontal machine burning. These three types are mainly divided according to the labor intensity of coal feeding.
Oil-fired thermal oil boiler uses fuel oil or gas as fuel, uses burner to burn fuel, takes heat conduction oil as heat carrier. Generally divided into vertical, horizontal two forms of structure, mainly according to the equipment space height of the two forms.
Differences between coal-fired thermal oil heater and oil-fired thermal oil heater
- Combustion device is different :
Oil-fired thermal oil boilers are using burners, generally zach, Wiesel, Riya Road and so on, using fuel oil light oil and residue oil. The coal-fired thermal oil boiler uses a grate. The grate is roughly divided into chain grate and reciprocating grate. The chain grate is generally used in the conventional furnace. Coal furnaces generally use bituminous coal, a few units also use white coal, but still mixed bituminous coal combustion. - Different energy consumption :
Generally, the calorific value of diesel oil is 10000kcal/m3, and that of bituminous coal is 5000kcal/kg. Calculated by 2.5 million kilocalories furnace, diesel oil needs 315m3/h, while bituminous coal USES 630KG/h. - Different configuration :
In order to achieve better thermal efficiency and environmental protection efficiency, coal furnace has more configurations, such as blower, dust collector (cyclone dust removal, water film dust removal), slag extractor and coal loader. The oil stove is equipped with a fuel tank and burner. - Different configuration methods :
General oil furnace for the round simple, vertical, horizontal, small can also be made into an integral, easy to transport. And the coal furnace is generally like more than 2 million made of square box furnace, this is for better heating, to achieve a higher heat exchange rate.
In addition, heat is transported by liquid phase, and the heat carrier after heat transfer is returned to the furnace body for continuous heating without waste heat discharge. It has complete operation control and safety monitoring device; Save electricity, water and operating costs. Because of its safety and energy saving, thermal oil heater has been widely used in various industrial fields.
