Advantages of coal-fired environmental protection boiler

2020-09-03 10:05    page view:

Guide: Environmental protection boiler is a relatively general concept. As the name suggests, environmental protection boiler refers to a boiler whose exhaust gas emission can meet environmental protection requirements. It does not refer to a certain type of boiler. After desulfurization and dust removal treatment, coal-fired boilers can also meet environmental protection requirements. Therefore, coal-fired boilers that have passed environmental protection standards are also environmentally friendly boilers.

  Environmental protection boiler is a relatively general concept. As the name suggests, environmental protection boiler refers to a boiler whose exhaust gas emission can meet environmental protection requirements. It does not refer to a certain type of boiler. After desulfurization and dust removal treatment, coal-fired boilers can also meet environmental protection requirements. Therefore, coal-fired boilers that have passed environmental protection standards are also environmentally friendly boilers.

  According to the fuel, environmental protection boilers can be divided into electric heating boilers, oil-fired environmental protection boilers, gas environmental protection boilers and coal-fired environmental protection boilers; according to their use, they can be divided into environmental protection boiling water boilers, environmental protection hot water boilers, environmental protection steam boilers and environmental protection organic heat carrier boilers, etc.;

  The advantages of coal-fired environmental protection boilers have the following four points:

1. Energy saving and high efficiency

  Atmospheric environmental protection boilers can convert black smoke into coal gas for combustion, saving coal consumption. The atmospheric environmental protection boiler is equipped with double-layer grate and two combustion chambers. If the coal in the upper combustion chamber does not burn well, it can continue to burn if it falls into the lower combustion chamber. At the same time, a primary air and a secondary air are also installed, and the fuel can get enough oxygen to burn fully. According to the user's on-site comparison, it saves about 30% compared to similar large bituminous coal boilers and about 50% compared to briquette boilers.

2. Environmental protection standards

  Atmospheric environmental protection boilers can burn all kinds of bituminous coal, and can quickly convert black smoke into gas for combustion. The chimney will not emit black smoke and purify fine dust and sulfur dioxide. After monitoring, all indicators have reached the national environmental protection standards.

3. Reliable quality

  The steel plate of the atmospheric environmental protection boiler is made of national standard steel plate. The materials are Q235A, Q235B, and international seamless steel pipes. The materials are 20﹟, GB3087, GB8163. The production materials and manufacturing processes are strictly in accordance with national standards. After testing, all indicators have reached national standards.

4. Operational safety

  The structure of the atmospheric environmental protection boiler is very compact, the floor area is small, the temperature is fast, it is pressureless operation, safe and reliable. The environmentally friendly pressure-bearing steam boiler is equipped with a number of safety protection devices. When the pressure is exceeded, the safety valve automatically opens to release steam to ensure safe operation.
