8l gas water heater

Three sources of noise noise pollution has become one of the three 8l water heaters pollution of modern society. We often see complaints and disputes due to the noise generated by the boiler in the news. Noise existing boilers relatively large, often the subject of complaints of users. According to the survey, most of the existing boiler noise in our country are not well controlled. Boiler noise produced mainly by the following reasons: 1, the boiler blower. Boiler blower noise is mainly frictional noise and airframe noise operation between the rotor and stator vibration caused by the vibration of air noise from the fan caused. Gas inlet device, since the high-speed air flow impact on the fan noise. 2, boiler pump. Boiler pump is usually noisy noisy water pump itself and the noise generated by the structure. 3, boiler exhaust. When the exhaust gas boiler, jet noise is generated when the high temperature and pressure vapor is injected into the atmosphere. Steel gas generated noise transmitted along the chimney, the chimney outlet formed noise.

In the accident investigation process, the reasons for 8l water heater explosion, nothing less than three points: gas (fuel), air and heat. Once the three reaches a certain level, causing the boiler exploded not far.

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, 8l water heater flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.

The CFB is a circulating fluidized bed 8l water heater in which a portion of the bed media (sand) is recirculated in the main furnace chamber. Primary fluidizing air is supplied below the bed with sufficient velocity to force the bed media and fuel particles upward through the furnace. Due to an expansion in cross-sectional area at the top of the furnace, the velocity of the existing flue gas is decreased causing sand and particles to drop out of the flow and fall back down the furnace. Some media and particles will continue onward toward the heat exchanger tubes and are collected using a series of U-beams designed to separate particulate and sand from the flow.
