Fuel flexibility is one of them. Industrial cfb boilers can burn a wide variety of fuels without a major penalty in performance such as coal residue, wood chips, sludge, agricultural waste, etc.

SZS series water tube boiler can burn gas and oil fuels, coal gas also including. Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system.

In Nov, 2016, ZBG singed a sales contract with clients in Malaysia, a set of 28 ton water tube boiler, which should meet DOSH standard as required.
DOSH Certification in manufacturing area is widely applied. Boiler exported to Malaysia, must follow local governments regulation.

In Nov, 2016, ZBG singed a sales contract with an aac plant in Bahrain. Our clients ordered two sets of horizontal autoclaves with 32 length and 1.4 Mpa pressure. And the two aac autoclaves will be produced under ASME standards.

ZBG singed a sales contract of 28 ton gas fired steam boiler with Malaysia clients in Nov, 2016, which will be produced under DOSH standard as required.

Combustion air pre-heat is another potential energy saving technique worthy of consideration. And it is an necessary boiler auxiliary equipment to save boiler energy and improve thermal efficiency.

Along with the increase of the world demand for alternative biomass energy, it has been revealed that the domestic market for sunflower husk pellets features a positive dynamic in development in boiler market. ZBG produced packaged sunflower hulls fired boiler with DZL and SZL series.

High pressure boilers use the forced circulation of water which ensures the positive circulation of water and increased evaporative capacity. Those cfb boiler require less heat of vaporization.

Coal fired power stations, are fitted with economizers. Economizers are commonly used as part of a heat recovery steam generator in a combined cycle power plant. In an power plant boiler, water passes through an economizer, then a boiler and then a superheater.

Boiler thermal efficiency% = 100 - (flue gas losses% + radiation losses% + blow down losses% - other losses%)
