steam boiler hot sale in sri lanka

Key condensing gas boiler condensing boiler key point is that condensing technology, is a new energy-saving, environmentally friendly technology; in fact, the principle is not complicated, simple generalization is the flue gas heat recovery through flue gas condensation. In conventional boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, or even higher, so that water produced during combustion of the fuel (e.g. natural gas: CH4 + 2O2 → CO2 + 2H2O) is in a state of steam superheater in the flue gas, with the smoke. the loss of gas from the chimney. Traditional boiler thermal efficiency is generally only 85% to 91%. The Henan fast condensing gas boiler side, that the exhaust gas temperature is reduced to 35-60 deg.] C, sufficiently recovered latent heat of condensation and sensible heat in the flue gas water vapor, maximum thermal efficiency of up to 108.9%.

Steam boiler model parameters of the gas boiler is the most common problem is a problem of scale, which we need to carry out cleaning and maintenance work. Gas boiler water treatment work is to prevent gas boiler fouling. However, due to improper or method of treatment for other conditions, often in some boilers have varying degrees junction scale. In order to ensure safe and economic operation of the gas boiler, for the scale to be cleared in a timely manner. Mechanical cleaning gas boiler 1. Method: When the gas boiler furnace has a loose scale and slag, after shutdown so that the cooling gas boiler, let go of boiler water, rinse with water after, to use flat shovel, wire brushes, and a motor milling descaling header. This method is relatively simple, the scale used for simple small gas boiler. However, labor-intensive, ineffective cleaning, easy to damage the boiler. 2. A gas boiler descaling pickling method: acid cleaning method using hydrochloric acid or nitric acid, most of the cleaning. Pickling solution by adding nitric acid or hydrochloric acid was added inhibitor of the corrosion inhibitor composition. This can eliminate the acid liquid boiler scale (scale except when nitrate, hydrofluoric acid to be added), and very few corrosion gas boiler. Descaling pickling has dissolved, exfoliation and slack action. 3. The cleaning gas boiler alkali cooking method: alkali cooking method cleaning descaling, pickling cleaning effect than the difference method, but since a base boiled loose scale, and therefore difficult to remove for the scale with hydrochloric acid, before acid It may be treated with a base to conduct a cooking method. Alkali cooking method is simple, relatively small side effects. The disadvantage is a long time cooking oven, more reagent consumption, and poor results.

Diqing in Yunnan Nonferrous Metals Co., Ltd. mainly engaged in Pulang copper mining, site selection, sales and other items. As we all know, in the copper smelting process, it consumes a lot of electricity and thermal power resources, which account for most of the hot water consumption. Combined with the actual demand Diqing company, to provide fast Boiler 1 stage electric heating hot water boiler of 2.1MW.

Use of superheater and reheater in claim 1, the working characteristics of (1) a high vapor pressure, pressure may reach a supercritical or more; (2) superheater and reheater within the boiler working fluid temperature of the highest member; (3) Steam (especially reheat steam) poor capacity of the cooling duct. 2, work requirements (1) to run a stable steam temperature should be maintained: fluctuations do not exceed -10 ~ 5 ℃; (2) superheater and reheater have reliable temperature control means so that changes in the operating conditions within a certain range when the steam temperature to maintain the rated; (3) minimizing the thermal variations between the parallel tubes.
