Cooper and brass is used for smaller size horizontal boiler because it is easily fabricated. An industrial horizontal boiler, originally used for supplying steam to a stationary steam engine. It is used in power plant, process industry and wherever a source of steam is required. The main components of horizontal boiler are feed water inlet, steam outlet, safety valve, firebox and chimney. These components need to control at every stage of the process. The size and form is depending upon application where it is needed. A horizontal boiler consists of firebox or furnace in order to burn the fuel and generate the heat.

Boiler scale formation. After a long run the boiler, the inevitable emergence of scale, the problem of corrosion, boiler scale formation is mainly due to the water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation, occurs in the furnace a series of physical, chemical the reaction final heating surface to form a hard, dense scale. 1, resulting in reduced heat transfer and the effect due to corrosion under the scale factor 2, resulting in reduced boiler waterwall furnace heat absorption, the boiler furnace exit temperature increases, so that the loss increases boiler 3, the fouling effect of reducing the water wall heat transfer, it is possible resulting in water wall water wall tube wall temperature increases lead to burst pipes, affect the safe operation of the boiler.

Issues related to pressure test of the boiler 1, the boiler pressure test what? Boiler pressure test pressure test is divided into working overpressure test of two. Hydrostatic test purpose is to test the strength and tightness of the pressure member. After the pressure member is generally repair, such as repair or replacement of part of the valve, the boiler tubes, headers, etc., and the boiler, a small repair work should be carried out after the pressure test. After installation of the new boiler repair boilers and boiler to replace a large area of ​​the heating surface, the operating pressure should be 1.25 times the over-pressure test. 2, how to prevent the boiler pressure test overpressure? Operating a water pressure test is an important relationship between the safety of the boiler must be careful to note: should carefully check the pressure gauge into the situation before (1) pressure test. (2) to the exhaust air accident drainage gate power is turned on, flexible switch, exhaust, water discharge flow line. (3) Test should have Chief Engineer professionals in the field, or a command specified by the person controlling the boosting speed can not be midway substitutions. (4) from the boiler pressure, off a small inlet damper, controls the boost speed does not exceed 0.3MPa / min. (5) to boost the operating pressure of the boiler 70%, also due to slow speed boost, and make prevents overpressure safety measures. 3. What pressure test eligibility boiler? (1) when the door is completely closed from Sheung timing smin the pressure drop: not more than 0.2 a high-pressure boiler for qualified 0.3MPa, pressure in the boiler does not exceed 0.1 ~ 0.2MPa acceptable. Pressure boiler pressure drop is less than 98kPa qualified per minute. (2) pressure members, and the weld metal wall and no mist droplets. (3) no residual deformation of the pressure member signs.
