Product introduction
Water quality standard
Technical parameters

1, Product range

Steam furnace, rated evaporation: 2-20t/h, rated working pressure: 1.25-2.5Mpa
Water heater, rated power: 2.8-14MW
Others: Special design and manufacturing can be carried out according to various parameter requirements put forward by users. Provide product types that meet customer needs and customize products.

Ⅱ, structural characteristics

1. Horizontal double-barrel water tube boiler, the boiler is composed of the upper part of the body and the lower part of the grate.
2. The boiler body is arranged longitudinally above and below the double boiler drum, the boiler drum and the water wall tubes on both sides form the radiant heating surface of the furnace, and the tube bundle between the upper and lower boiler drum forms the convection heating surface.
3. The chain grate divides the air into the bin, the air volume of each air bin is adjusted independently, and the grate is stepless speed regulation.
4. After the completion of the grate building furnace below SZL4/SZL2.8, the grate building of SZL6/SZL4.2 and above needs to be built on site (refractory materials and equipment are sent to the site, and the boiler quotation does not include the furnace building cost.)
5.SZL20/SZL14 boiler heating surface is independently made, welding work is completed in the factory, welding quality is reliable, high assembly degree, short installation period.

Ⅲ, performance advantage

(1) High-efficiency and energy-saving.
1. The boiler heating surface is adequately arranged, and the boiler starts heating up quickly; Flue gas multi-return heat transfer, high thermal efficiency.
2. The boiler tail is arranged with efficient economizer and air preheater to absorb heat, reduce smoke exhaust temperature, improve thermal efficiency and reduce fuel consumption.
3. The boiler adopts high-quality insulation materials and special construction technology, and the heat loss is small.
4. The furnace is specially designed to improve the efficiency of heat radiation, the grate is specially designed to divide the air into the bin, and the air volume of each air bin is independently adjusted to make the fuel burn evenly and fully, and the fuel has wide applicability.

(2) Safe and reliable
1. Furnace radiation heat exchange surface close drainage water cooling pipe structure, good sealing.
2. Boiler operation adopts remote and near-ground multi-parameter monitoring interlock, complete automatic control and testing instruments.
3. Combining industrial automation control technology, Internet technology, computer software and artificial intelligence technology to establish an industrial boiler Internet of Things platform, which can realize remote human-computer interaction and data sharing.

(3) Environmental protection Appropriate flue gas treatment equipment is configured according to local environmental protection requirements, and flue gas emissions meet environmental protection requirements.

The water quality standard of steam boiler when using chemical water treatment outside the furnace

Water quality requirements:GB/T1576 Water quality of industrial boilers

Note: Dissolved oxygen content: When the rated evaporation capacity of the boiler is ≥6t/h, it should be deoxygenated; when the rated evaporation capacity is < 6t/h, if local corrosion is found in the boiler, deoxygenation measures should be taken. The oxygen content of the boiler feed water for the steam turbine should be ≤0.05mg/L

Water quality standard for hot water boilers

Coal-fired steam boiler(2-20t/h  double drum)

1、The feed pump is selected according to the steam pressure selected by the user.
2、The induced draft fan shall do the final parameter verification according to the flue gas treatment equipment selected by the user (the flue gas resistance increases after the addition of environmental protection equipment).

Coal-fired hot water boiler(2.8-14MW  double drum)

1、The feed pump is selected according to the user's hot water temperature.
2、Fan according to the user selected flue gas treatment equipment to do the final parameter verification (increase the flue gas resistance after adding environmental protection equipment)
